SECTION I. INTRODUCTION
Your new Reverse Osmosis (R.O.) Drinking Water
System uses a combination of filtration technologies
to reduce unwanted contaminants in a water supply.
The following steps combine to give you the best
inclear sparkling drinking water:
MECHANICAL FILTRATION/ACTIVATED
CARBON–The sediment prefilter will remove
the larger particles such as silt, rust and scale. Its
5 micron (equal to 0.0002 inch) nominal rating
helps to give maximum life to the R.O.
Membrane. The activated carbon in the Prefilter
will remove any chlorine that may be present in
the feed water. This pretreatment is also necessary
for membrane protection.
REVERSE OSMOSIS MEMBRANE–The R.O.
Membrane is the heart of the filtration system. It
is designed to reduce the dissolved mineral
content of the water. Minerals picked up in the
environment by the water are measured as Total
Dissolved Solids (TDS). In the Reverse Osmosis
process, dissolved minerals are separated from the
incoming water (Feed Water) to produce the
product water (the Permeate). The excess
minerals are rinsed to drain (the Reject Water).
The membrane is a specially constructed, fully
aromatic polyamide film and is classified as a Thin
Film Composite (T.F.C.).
The spiral wound construction of the R.O.
Membrane provides maximum surface area for
water production and is less susceptible to fouling
by particulate matter, turbidity and colloidal
materials.
ACTIVATED CARBON–The Activated
Carbon Post Filter contains carbon particles with
a vast network of pores. The tremendous surface
area of these pores (typically 800–1200 square
meters per gram of carbon) gives the carbon very
good adsorptive sites for substances that
contribute to tastes and odors.
IN–LINE ACTIVATED CARBON POST
FILTER–The In–Line Activated Carbon Post
Filter is located after the Holding Tank and
reduces the tastes and odors that may pass through
the system. It adds a final polish to the water.
AUTOMATIC SHUTOFF VALVE–The
ASO Valve senses when the product water tank is
full and closes the feed water supply to prevent
excess reject water from going to drain when the
unit is not producing water.

nuts for mounting the manifold, or concrete
anchors for hanging on basement wall.
Additional tubing or tube connectors. Plastic
wire ties for organizing tubing.
* The TDS Monitor may be necessary to conform to state or
local codes, check with the local plumbing authority.
B. Tools Recommended for Installation
The following tools will cover most of the
installation sites encountered:
1. 3/8" variable speed electric drill.
2. Extension work light with outlet.
3. Safety glasses.
4. 1¼" porcelain hole cutter kit.
5. 1¼" Greenlee hole punch and 1/8" and ½"

14. Teflon tape.
15. Wide masking tape or duct tape.
16. Plastic tubing cutter.
17. Extra plastic tubing.
18. Low range air pressure gauge.
19. Bicycle hand air pump.
20. Small bottle of liquid chlorine bleach.
21. Graduated measuring cylinder.
22. Paper towels, wisk broom and assorted clean
up materials.
C. Site Selection for Major System Components
The R.O. System was designed to fit under a sink,
however, because of space limitations or other
reasons, the system’s flexible design allows for
other locations. When determining the location
remember that access to a cold water tap line, the
household drain, and ease of filter replacement are
important considerations.
All components and tubing should be located in
an area which is not exposed to freezing
temperatures. If winter temperatures are severe,
the area should be above the minimum
temperature listed in Table B, page 3 for proper
performance. Do not expose unit or tubing to
direct sunlight.
1. Dispensing Faucet–The faucet should be
placed near the sink where drinking water is
normally obtained. Convenience of use (filling
of water pitchers and glasses), and an open
area beneath the faucet under the sink for
attaching product and drain tubing are
considerations. A 2" diameter flat surface is
required above and below the installation site.
The thickness of the mounting surface should
not exceed 1¼". Watch for strengthening
webbing on the underside of cast iron sinks.
2. Drinking Water Holding Tank–The Holding
Tank may be placed where it is convenient
within 10 feet of the faucet; under the sink or
in an adjacent cabinet are the best choices. If a
longer run of tubing is required, the tubing
should be the 3/8" diameter OD size to prevent

5
a high pressure drop. Remember, these tanks
can weigh up to 30 pounds when full of water;
a firm, level area is required.
3. R.O. Manifold Assembly–The manifold can
be installed on either the right or left side of
the under–sink area or a cabinet. The right
side is recommended because all the tubing
will be to the back of the cabinet and out of
the way. Installation in the basement is also an
option, one location is near the laundry/utility
sink where cold potable water and drain access
is handy. The mounting location should allow
adequate clearance and accessibility for
cartridge changes.
4. Feed Water Connection–The Feed Water
Saddle Valve should be located as close to the
manifold assembly as possible. USE A
POTABLE COLD WATER SUPPLY ONLY.
Softened water is preferred as it will extend
the life of the R.O. Membrane.
5. Drain Connection–The waste water must go
to drain through an anti–siphon air gap. The
air gap is provided for in the base of the faucet.
If discharging into a utility sink or standpipe,
an air gap of greater than 1" above the flood
rim must be provided.
Do NOT connect the system drain line to the
dishwasher drain or near the garbage disposal.
Backpressure from these units may cause the
air gap to overflow.
SECTION IV. INSTALLATION STEPS
All plumbing should be done in accordance with
state and local plumbing codes.
NOTE: Some codes may require installation by a
licensed plumber; check with the local plumbing
authority prior to installation.
In restricted under–sink areas, it may be easier to
install the faucet first. Allow adequate tubing lengths
for any final component position.
A. Faucet Installation–The faucet contains an anti–
siphon air gap. While the system is producing
water, the drain water flows from the R.O.,
through the air gap and then to the household
drain. The purpose of the air gap is to prevent
water in the drain from backing up into the R.O.
Drinking Water System.
NOTE: For proper installation the Air Gap
Faucet has a critical level line “CL”marked on its
body and should be mounted so that the “CL”line
is at least one (1) inch (26mm) above the flood
level rim of the sink.
The easiest installation is to use an existing spray
attachment hole. If the spray faucet hole is not
available, then the sink top must be drilled.
Choose a convenient location as described in
Sec. III, C.1, page 4.
1. Mark the location of the center of the faucet
base.
2a. Drilling a stainless steel sink:
•Center punch the hole to provide a starting
point for the drill.
•Start with a smaller drill as a pilot, and then
drill a ½" diameter hole to accept the bolt of
a 1¼" Greenlee Hole Punch (1¼" chassis
punch).
•Clean away any chips.
•Install the punch and tighten the nut to cut
the hole.
•Deburr any sharp edges.
2b. Drilling a porcelain sink:
It is best to use a special 1¼" diameter cutter
designed for porcelain. A carbide tipped
masonry bit is a second choice.
•Place a piece of tape over the area to be
drilled to help prevent chipping.
•Drill a pilot hole for the porcelain cutter. Use
the pilot drill supplied with the kit or a
carbide tipped drill.
•When drilling the 1¼" hole, drill slowly and
carefully; the porcelain chips easily.
•After drilling, clean the area well. Iron
filings, if left in place, can cause rust stains.
2c. Drilling a counter top:
NOTE: The counter top must be less than
1¼" thick. (See Sec. IV, A.2b, page 5.) Treat
ceramic tile as porcelain until the tile is
penetrated, then use the carbide tipped metal
cutter.
Formica counter tops may be drilled with a
good 1¼" wood bit, drilling a 3/32" pilot hole
will help keep the bit going straight.

lance does not protrude from the gasket. It
may have to be pushed in.
•Assemble the Feed Water Saddle Valve on
the tubing.
–for 3/8" OD tubing use the back plate side
with the small groove to prevent distortion
of the tubing.
–for larger tubing (up to 5/8" OD) use the large
groove of the back plate.

allow the water to run for a few minutes to
flush any debris caused by the installation.
•Close the faucet and check the Feed Water
Saddle Valve for leaks.
C. Drain Clamp Installation
Choose the drain outlet location per Sec. III, C.5,
page 5.
The following are instructions for discharging into
the sink drain pipe. (Refer to Fig. 1, page 1.)
1. Position the Drain Clamp on the sink drain
pipe above the drain trap. Allow room for
drilling. Tighten securely.
2. Use a battery powered or properly grounded
drill. Using the Clamp port as a drill guide,
drill a 7/32" hole through the wall of the drain
pipe. Do NOT penetrate the opposite side of
the pipe.
3. Locate the 3/8" Black Drain Tubing which is
shipped loose in the box.
NOTE: When cutting the polytubing make
clean, square cuts, failing to do so could result
in poor connections and possible leaks.
CAUTION: The lowest point of the line
should be the point of connection to the Drain
Clamp. There should be no sag in the line as

•To pierce the tubing, turn the Valve Handle
fully clockwise (inward). A small amount of
water may escape from the outlet until it is
fully pierced.
•When you feel the Valve Handle firmly
seated in the clockwise direction, the copper
tube is pierced and the valve is closed.
2b. To install on (hard) Steel or Brass Tubing
supply line.
•The supply line should now be drained. Use a
battery powered or properly grounded drill to
avoid shock hazard.
•Drill a 3/16" hole in the supply line; (do not
drill through the opposite wall).
•Turn the handle to expose the lance no more
than 3/16" beyond the rubber gasket.
•Place the body of the valve over the hole so
that the lance fits into the hole.
•Assemble and tighten the brass screw.
•Turn the Valve Handle clockwise (inward)
until firmly seated. The valve is closed.
3. With the Feed Water Saddle Valve closed,
open the sink faucet and the water supply and

8
this may cause excessive noise as the reject
water is flowing to drain.
Firmly press one end of the tubing over the 3/8"
drain outlet hose barb on the Dispensing
Faucet. Allow the tubing to relax, then press
firmly again to insure proper seating. No
connectors are required when attaching hose
to Hose Barbs. Route the tubing to the Drain
Clamp and trim to length.
•Refer to Fig. 4, page 7. To connect the Drain
Tubing, install the Compression Nut and the
Brass Insert.
•Insert the tubing into the Drain Clamp and
tighten the Compression Nut.
D. R.O. Manifold Assembly Installation
Locate the site per Sec. III, C.3, page 5. Various
installation sites will require different types of
mounting fasteners; be sure the fastener selected
will provide a firm, solid mounting. A support
panel may be necessary on thin cabinet walls or to
span between wall studs on particleboard or
drywall.
Do not drill through exterior cabinet walls or
leave sharp wood screw points exposed in readily
accessible cabinet interiors.
The close proximity of a dishwasher or a trash
compactor may require special fabrication of a
mounting plate.
1. The mounting bracket will accept either #10
or #12 (5mm) mounting screws spaced on 9½"
(24 cm) centers. Allow at least 4" (10 cm) of
clearance beneath the filter housings to
accommodate filter changes. Mark the two
locations (the bracket can be used as a
template). Install the screws and tighten them
until the heads are about 5/8" from the wall.
2. Locate the ¼" Red Feed Water Tubing.
Remove the red plug from the fitting labelled
“In”on the manifold and insert the tubing.
Reference the special supplement sheet in the
carton for proper connection of all tubing and
removal of plugs. Run the tubing along its
course to the Feed Water Saddle Valve, trim to
length. (Refer to Fig. 1, page 1.)
Refer to Fig. 3, page 6. To the end of the red
polytube install the Compression Nut, the
Plastic Ferrule, and the Brass Insert. Connect
to the Feed Water Saddle Valve.
3. Locate the ¼" Black Drain Tubing. Remove
the black plug from the fitting labelled “Drain”
on the manifold and insert the tubing. Run the
tubing along its course to the ¼" Hose Barb on
the Dispensing Faucet, trim to length and
connect by firmly pressing over the barb.
Allow the tubing to relax, then press firmly
again to insure proper seating.
4. Locate the ¼" yellow tubing with the tee
attached to one end. Remove the yellow plug
from the fitting labelled "Out" on the manifold
and insert the tubing.
5. Locate the 3/8" Blue Product Water Tubing.
Firmly press one end into the tee and the other
end into the faucet connector. (Refer to Fig. 1,
page 1.) The fittings will grab the tubing and
seal it in place. Make sure the tubing is pressed
all the way in to create a pressure tight
connection.
NOTE: If you want to pull the tubing out for
some reason, push the ring around the tubing
in and pull the tubing out.
6. Hang the Manifold Assembly on the mounting
screws and tighten. DO NOT
OVERTIGHTEN.
7. Remove the wrapping from the
In–Line Activated Carbon Post Filter. Slice
the 3/8" Blue Polytube where it would be
convenient to install and change the In–Line
Filter. Make a clean straight cut to insure
proper connections. The “Out”port on the
In–Line Filter should be toward the faucet.
Firmly press in the tubing. The fittings will
grab the tubing and seal it in place. Make sure
the tubing is pressed all the way in to create a
pressure tight connection.
E. Position the Drinking Water Holding Tank and
Make the Final Hose Connections.
1. Check the tank precharge pressure. Make sure
it is between 5 to 7 psig. If not, use a bicycle
hand pump or other pump to bring the
pressure up to the 5 to 7 psig range.
2. Pull the cap/plug off the top of the tank where
the Tank Shut–Off should go. (Refer to Fig. 1,
page 1.)
3. Wrap the white teflon tape, included in the
box, three times around the ¼" male outlet
thread. Wrap in the direction of the threads
(clockwise when looking down on the Holding
Tank). The tape will act as a thread sealant.
Screw on the Holding Tank Shut–Off Valve.

9
4. Locate the 3/8" Yellow Tubing. Firmly press one
end into the Holding Tank Shut–Off Valve
and the other end into the tee. (Refer to Fig.
1, page 1.) The fittings will grab the tubing
and seal it in place. Make sure the tubing is
pressed all the way in to create a pressure tight
connection.
Note: If the optional RO Comparator is used,
its location and the location of its test cells
should be determined at this time.
The "In" Cell should be located in the Red
Feed Water Tubing line before the R.O.
System.
The "Out" Cell should be located in the 1/4"
Yellow Tubing Line, between the "Out" Port
and the Tee.
F. Start Up
At time of start up and each time the filters are
changed the system should be sanitized (also see
Operation and Maintenance Sec. V, B.1–4,
page 10).
1. Sanitizing the system. Use a drip pan to aid
clean–up.
NOTE: The system should be sanitized
BEFORE installing the Sediment/Carbon
Prefilter, the Activated Carbon Post Filter or
the R.O. Membrane.
•Use a good quality unscented 5¼% liquid
chlorine household bleach.
•Open the Dispensing Faucet by lifting the
black handle and open the Holding Tank
Shut–Off Valve (the handle should be
parallel with the valve body).
•Remove the plug on the underside of the
manifold labelled “SEDIMENT/CARBON”.
Pour one capful of bleach (this is
approximately 2 tsp. or 10 ml) into one of
the white Housings. Insert a Housing O–ring
into the Housing groove, (press firmly in
place). Engage and firmly tighten the
Housing hand tight only.
•Remove the plugs labelled “MEMBRANE”
and “ACTIVATED CARBON”from the
underside of the manifold. To each of the
remaining white Housings, add one capful of
bleach. Insert a Housing O–ring, engage and
firmly tighten the Housings hand tight only.
•Slowly open the Feed Water Saddle Valve
(turning counter clockwise).
•As soon as the water begins to come out of
the Dispensing Faucet, close the Faucet.
•Let stand for 15 minutes.
NOTE: During this time, check the system
carefully for leaks.
•At the end of 15 minutes, CLOSE the Feed
Water Saddle Valve and open the Dispensing
Faucet.
•Allow the Holding Tank to completely drain,
then remove the Sediment/Carbon Filter
Housing (the farthest of the three from the
In–Out ports), empty, and install the
Sediment/Carbon Prefilter. Firmly tighten
the Housing hand tight only.
•Remove the Activated Carbon Filter
Housing (the closest of the three to the
In–Out ports), empty, and install the
Activated Carbon Post Filter. Firmly tighten
the Housing hand tight only.
2. Installing the R.O. Membrane:
•Remove the R.O. Membrane Housing, (the
middle one), and empty.
•Insert the Membrane up into the manifold.
(The O–rings should be up toward the
manifold.) Check the Housing O–ring for
proper position in its groove, engage and
firmly tighten the Housing hand tight only.
3. Rinsing the system:
•Slowly open the Feed Water Saddle Valve
fully counter clockwise.
•The Holding Tank Valve should be open.
•Check the Air Gap Window on the
Dispensing Faucet to be sure that the drain
water is flowing. (Refer to Figure 2, page 6.)
The R.O. System is now making water.
•Do not open the Faucet for at least 6 hours.
•Do not use the first three full tanks of water.
CAUTION: The R.O. Membrane is shipped
with a preservative in it (0.5% sodium
metabisulfite). This will be rinsed out with
the first water produced. Allow the Holding
Tank to fill (overnight) and discard the first
three full tanks of production. It takes
approximately 6 hours to make a full tank.
When the Faucet is first opened, expect air
and carbon fines (very fine black powder)
from the In–Line and Activated Carbon Post
Filters to be rinsed out. This is normal for the
first tank of water or after the Activated
Carbon Post Filters are changed.

SECTION V. OPERATION & MAINTENANCE
A. Normal Operation
1. It is normal for the Total Dissolved Solids
(TDS) of the water to be higher than normal
during the first 5 gallons of operation, this is
due to the sanitizing solution and the new Post
Filters. After this water is rinsed to drain, the
removal rate should stabilize at a value of
greater than 75%. The optional R.O.
Comparator measures the TDS reduction and
gives an indication of proper performance.
Water pressure affects the production rate and
quality.
2. R.O. systems produce drinking water at
relatively slow rates, it can take up to 6 hours
or more to fill the Holding Tank. Normal
operation is to let the Holding Tank fill with
water and then draw water as needed. When
the pressure in the Holding Tank falls to a
given pressure (as the water is being used) the
Automatic Shut–Off Valve (ASO Valve) will
start water production and the system will
refill the Holding Tank. When the Holding
Tank is full and no water is being used, the
ASO Valve will automatically shut off the feed
water to conserve water. The more water that
is used (up to the capacity of the system) the
better the R.O. system will function. Other
uses for the water are flowers, pets and rinsing
glassware.
With each use it is recommended that you
turn the tap for at least 10 seconds prior to
using water. This is especially important if the
water tap has not been used daily.After periods
of non–use, such as a week of vacation, it is
better to empty the Holding Tank and allow
the system to produce fresh water for use. If
the system is not used for 3–4 weeks or longer,
it is a good idea to resanitize the system and to
change the prefilter and post filters.
B. Changing Filters
THIS R.O. SYSTEM CONTAINS FILTERS
WHICH MUST BE REPLACED AT REGULAR
INTERVALS TO MAINTAIN PROPER
PERFORMANCE. USE ONLY FACTORY
APPROVED FILTERS.
The recommended interval for changing the
filters (not the R.O. Membrane) is every six (6)
months. Typical T.F.C. Membrane life expectancy
is three years. Local conditions may dictate more
frequent changes.
NOTE: If the R.O. Membrane is to be replaced,
see Sec. IV, F.1–3, page 9, for the proper
procedure.
Use a drip pan to catch any water that may spill
when the Filter Housings are removed. Refer to
Fig. 1 page 1 for component location.
1. Close the Feed Water Saddle Valve by turning
fully clockwise and open the Dispensing
Faucet by lifting the handle. Allow the
Holding Tank to empty.
2. Loosen and remove the Sediment/Carbon
Filter and the Activated Carbon Filter
Housings. Discard the filters.
3. Wash the inside of the Housings using a mild
detergent and a soft cloth. Do not use abrasive
cleaners or pads. Thoroughly rinse all soap
from the Housings before reassembly.
4. To sanitize the system and replace the filters:
NOTE: The system should be sanitized before
installing the Sediment/Carbon Prefilter and
Activated Carbon Post Filter.
•Use a good quality unscented 5¼% liquid
chlorine household bleach.
•Add one capful of bleach (this is 2 tsp. or
10 ml) to the Sediment/Carbon Filter
Housing and temporarily install the Housing
without the Sediment/Carbon Prefilter.
Check the Housing O–ring for proper
position in its groove, engage and firmly
tighten the Housing hand tight only.
•Add one capful of bleach to the Activated
Carbon Filter Housing. Carefully fill the
Housing with tap water and temporarily
install the Housing without the Activated
Carbon Post Filter.
•The Dispensing Faucet should be open,
slowly open the Feed Water Saddle Valve.
•As soon as water begins to drip out of the
Dispensing Faucet, close the Faucet.
•Let the system stand for 15 minutes.
•At the end of 15 minutes, in the following
order, close the Feed Water Saddle Valve,
close the Holding Tank Valve and open the
Dispensing Faucet to release the pressure.
•Remove the Sediment/Carbon Filter
Housing and empty. Remove the wrapping
and install the Sediment/Carbon Prefilter.
Firmly tighten the Housing hand tight only.

11
•Remove the Activated Carbon Filter
Housing and empty. Remove the wrapping
and install the Activated Carbon Post Filter.
Firmly tighten the Housing hand tight only.
•Disconnect the yellow product water tubing
that runs from the Holding Tank to the Tee
(see Fig. 1, page 1). Put 50 drops of bleach
(this is ½tsp. or 3 ml) into the tubing and
reconnect it to the Tee.
NOTE: Now is the convenient time to
change the In–Line Activated Carbon Post
Filter, see Sec. V, C.1–6, page 11.
•Slowly open the Feed Water Saddle Valve.
When water begins dripping out of the
Dispensing Faucet, in the following order,
close the Faucet and then open the Holding
Tank Valve.
•Do not open the Faucet for at least 6 hours.
•Discard the first three full tanks of water
produced, they will contain chlorine.
C. Changing the In–Line Activated Carbon Post
Filter
1. Close the Feed Water Saddle Valve by turning
fully clockwise.
2. Close the Holding Tank Valve and then open
the Dispensing Faucet to release the pressure.
3. Remove the In–Line Activated Carbon Post
Filter. Disconnect the used Post Filter by
pressing in the connector’s collar and at the
same time pulling the tube out of the fitting.
Unscrew the fittings on the In–Line, re–Teflon
tape them and install them on the new Post
Filter. Do not over tighten the fittings.
4. Firmly reconnect the polytubes to the new
Post Filter. (Refer to Fig. 5 above.)
5. Slowly open the Feed Water Saddle Valve.
6. When water begins dripping out of the Faucet,
in the following order, close the Faucet and
open the Holding Tank Valve. When the
Faucet is first opened, expect air and carbon
fines (very fine black powder), from the new
Post Filter to be rinsed out. This is normal for
the first tank of water.

SECTION VI. TECHNICAL DATA
A. Water Quality
Water quality is normally measured with a special
meter that measures the water’s ability to conduct
electricity. The more dissolved solids in the water,
the higher the conductivity. The results are
usually reported in Parts per Million (ppm) or
Milligrams per Liter (mg/l) of Total Dissolved
Solids (TDS). (Although technically they are not
exactly equal, in most discussions ppm = mg/l.)
R.O. Membranes are rated by the amount of
dissolved solids that are rejected. This rating is a
ratio of the TDS in the feed water to the TDS in
the product water and is reported as Percent
Rejection. If the feed water contained 100 ppm of
TDS and the product water contained 10 ppm of
TDS, 90 ppm have been rejected and the reject
ratio is 90%.
Percent Rejection =
Feed TDS–Product TDS x 100%
Feed TDS
EXAMPLE: Feed water is 500 ppm TDS and the
product water is 75 ppm TDS.
Percent Rejection = 500 –75 x 100%
500
Percent Rejection = 0.85 x 100% or 85%

12
C. Net Pressure Differential
Most R.O. Membranes are rated at a standardized
condition of 77°F (25°C) and 65 psig (450kPa)
discharging to atmospheric pressure.
Product water quality and quantity greatly depend
upon the Net Pressure Differential (∆p) across
the R.O. Membrane. This pressure differential is a
summation of the feed water pressure at the
Membrane, which tries to push the water through,
the pressure in the Holding Tank, which tries to
push the water backwards and the osmotic
pressure, which also tries to push the water
backwards.
The Osmotic Pressure is in proportion to the
dissolved minerals in the water and can be
approximated by 1 psig for each 100 ppm of TDS.
EXAMPLE: A feed water with 1500 ppm of TDS
would exert a backward pressure of about 15 psig
on the membrane.
Net Pressure Differential =
Feed Water Pressure –Holding Tank Pressure –
Osmotic Pressure
The higher the net pressure differential, the
higher the quantity and quality of water produced.
Some loss of production is normal when using a
pressurized Holding Tank.
B. Water Quantity
Water quantity is termed Flux or Product Water
Rate and is measured as the amount of water
produced in one day. It is reported as Gallons per
Day (gpd) or Liters per Day (lpd).
The flow of water to drain is the Reject Water
Rate and is measured as Gallons per Day (gpd) or
as Milliliters per Minute (ml/min).
Milliliters per minute x 0.38 = gallons per day
EXAMPLE: The drain flow will fill a graduated
cylinder to the 150 ml mark in one minute.
150 ml/min. x 0.38 = 57 gpd
If the container available measures ounces, use
the following conversion:
Ounces per minute x 11.2 = gallons per day
EXAMPLE: The product flow will fill 2½ounces
in two minutes.
2.5 oz. ÷2 min. = 1.25 oz./min.
1.25 oz./min. x 11.2 = 14 gpd
The Reject Ratio is the amount of water produced
compared to the amount of water flowing to drain.
Reject Ratio = Reject Rate_
Product Rate
EXAMPLE: The product rate is 14 gpd and the
reject rate is 56 gpd.
Reject Ratio = 56 ÷14
Reject Ratio = 4 or 4–to–1
The Percent Recovery is another way to measure
the amount of water produced as compared to the
amount actually used.
% Recovery = Product Rate x 100%
Feed Rate
NOTE: The total flow or feed water rate into the
system is the sum of the product flow and the
drain flow.
EXAMPLE: The product water rate is 14 gpd and
the drain water rate is 56 gpd.
Feed Rate = 14 gpd + 56 gpd = 70 gpd
% Recovery = 14 gpd x 100%
70 gpd
% Recovery = 0.20 x 100% or 20%
