General Description
The use of reclaim water has become an important method for the car wash operator to
reduce his / her operating expenses (water and sewer costs) and start-up costs (impact
and connection fees). Many municipalities are now requiring the use of water reclamation
systems in car wash operations and operators are continually looking for ways to increase
prots. As a result, reclaim systems are becoming essential in the overall operation of the
wash.
Reclaim water is the re-use of water that has already been used in the wash and recovered
by the drain system in the wash bay. Most drain systems consist of a catch basin to settle
out the large solids, followed by a series of underground settling tanks to remove oil and
grease, oatable materials and settle-able solids. Overow water from the last reclaim tank
is then discharged to sewer or through an oil / water separator and then to a sewer.
Water from the reclaim tanks contains solids that have not settled within the tank. These
solids are typically small in size (less than 150 microns) and consist of clay and silt. These
solids can increase wear on pumps, piping and nozzles, and increase the potential of
plugging nozzles. The environment inside reclaim water tanks will promote unwanted
biological growth. Anaerobic bacteria grows in the absence of oxygen, this bacteria will
grow in the reclaim tank. Anaerobic bacteria produces hydrogen sulde and methane gas
that has an odor similar to rotten eggs. A properly designed reclaim system must both
remove solids and provide odor control.
A PurWater reclamation system takes water from the last compartment of the reclaim tank
and treats it further so that the quality is acceptable for re-use in the wash. The PurWater
reclaim system also returns a portion of the water back to the reclaim tank to provide
biological / odor control. Reclaimed water that is treated by a PurWater system can then
be used for the undercarriage, side panel blasters, mitters, high pressure rinse cycles,
and landscape irrigation. Using reclaimed water on these applications greatly reduces
the overall amount of city water required by the wash. It also reduces the amount of
water discharged to sewer. The Reclaim treats 100% of the water entering the tanking and
typically, 60-75% of the water used on the car can be reclaimed water.
PurWater Reclaim System
The PurWater Reclaim System consists of cyclonic separators to remove solids down to
the 5 micron range and one of two methods (air sparger, or ozone addition) to control odor
and biological growth. The system is contained on a compact frame with its own pump /
motor and controls. The system will recirculate water continuously back to the reclaim tank
system for odor and biological control. When a demand for reclaim water is received from
the wash, the system will provide treated reclaim water at a set pressure of 40psi.

General Description (Cont)
PW 050/100/200/300/350/400-M5 (5 Micron) Series Systems
The PW 050/100/200/300/350/400-5M series systems consist of high e󰀩ciency cyclonic
separators, a pump / motor, controls and one of two odor control systems, either an
air sparger, or ozone addition. The standard systems are designed to treat 30, 60, 90,
120, and 160 Gallons Per Minute (GPM) of reclaim water. The new generation of high
e󰀩ciency cyclones will remove down to 5 micron solids, so that the treated water can
be used by high pressure touchless or friction in-bay automatics as well as tunnel wash
applications. The system utilizes a Variable Frequency Drive (VFD) on the pump motor
which is controlled by the wash demand, to vary the amount of water that is treated and
delivered. Water is recirculated back to the reclaim tanks. This is a continuous process
both when water is demanded by the wash and when there is no demand. Up to three
di󰀨erent activation inputs from the wash are incorporated into the control box. The PW050/
100/200/300/350/400-5M system piping also incorporates a city water intake line for use
as: 1) a bypass solenoid to meet wash water demands in case the system is not operating
due to a system fault; and 2) an automatic pump prime operation for system start-up.
Air Sparger
Biological and odor control are accomplished by using one of two methods, depending
upon the model number supplied. The rst method uses an air sparger (models ending in
5MAS), which is mounted within the reclaim tank above the water level. The air sparger
will bring in air as water is passed through the sparger. The aerated water will add oxygen
to the tank water which will control the anaerobic bacteria growth. The location of the air
sparger is noted on page 12 showing the discharge to be 6”-12” o󰀨 the surface of the water
for maximum aeration.
Ozone
The other method utilizes ozone to kill the bacteria (models ending in 5M040, 5M12O or
5M24O). Ozone is a contact killing agent, similar to chlorine used in city water. Ozone (O3)
is generated by concentrating the oxygen (O2) in ambient air and passing the concentrated
oxygen through a high voltage electric current to produce ozone. The ozone laden gas
is then inducted into the recirculation water stream and into the reclaim tank to kill the
bacteria. The ozone line is terminated in a “T” as noted on page 13 and placed 3,000
gallons prior to the suction lines.
Caution: Inhaling concentrated ozone can create severe breathing
problems. Precautions must be made to prevent exposure to
concentrated ozone.

and sizes are all shown in the drawings. It is highly suggested that two suction lines be included when designing and
installing the plumbing - one primary and one spare. It is also strongly suggested that the suction lines be pressure
tested and monitored during backll of the trench. Note: The suction line size is 2” for a PW100 / 200 / 300 and is 3” for
a PW350 or PW400

Tanking - Preinstallation
Reclaim Tanks
PurWater does not supply the underground reclaim tanks. These are typically precast
concrete vaults that are sourced locally, however, it is required that the tanks comply
with the following design parameters to ensure a successful operation. NOTE: if the
local tanking is atypical to design - contact PurWater for assistance. The tanking,
underground plumbing, and stub-up locations in the equipment room are important
key factors to have an e󰀨ective, e󰀩cient running Reclaim system.
Location Consideration for Tanks
• Locate the reclaim tanks close to the equipment room to minimize the length of
suction pipe to run to the reclaim unit.
• Locate the reclaim tanks so that bends and elbows are minimized on the suction
piping. “Double 45’s” or “Sweeps” rather than 90’s are highly recommended.
• Keep the suction piping below the reclaim pump inlet.
• For ozone units, the reclaim tanks should be located outside the wash bay and
equipment room in an area that is well ventilated. If located inside - the tanks should
be sealed and vented to the outside.
Note: The tanks can be congured end-to-end as shown in the drawings on
pages 12 & 13 or side by side. Whatever is best for the site layout is ne.

arrow path, the suction lines are located in tank #3 chamber #2. One of the suction lines is connected to the
basket inlet and one is a spare.

Interconnecting Piping- Critical to System Functionality
• The piping between the tanks/compartments will set the liquid level in each tank.
The elevation and downward elbow help prevent oating material and settled
solids from moving to the next tank.
• For the PW050/100 / 200 / 300 series, the interconnecting piping needs
to be a minimum of 4”. For PW350 / 400 / 700 series, the minimum is 6” to help
with  ow through the tanks.
Sewer Overow
• The sewer overow connection is above the normal liquid level and will normally
overow while washing vehicles.
• The sewer connection should slope downward to the main sewer line.
• There must be a backow preventer installed between the reclaim tanks
and the main sewer line to prevent sewage from entering the reclaim tanks.
Low Level Float Switch
• PurWater will supply one “Normally Closed” two-wire (yellow oat) level switch,
(Float is not required in standard underground setups but highly recommended.)
• The oat should be wired into a water-tight junction box within the last reclaim tank
and wired through the 1” conduit to the PurWater unit in the equipment room.
• The oat should be installed a minimum of 12” above the bottom of the check
valve when the oat is in the down position.
Misc. Items - Reclaim Tank Plumbing
• Piping and conduit materials should be PVC. PurWater recommends using
schedule 80 pipe as it is more durable than schedule 40.
• All piping to/from the PurWater Unit should be accessible from a manway for
frequent maintenance and troubleshooting.
• A spare or “back-up” secondary suction line is shown on standard drawings. Do
not overlook installing a back up suction line.
• All oor drains emptying into the reclaim tanks should be piped to go below the
water level within the tanks. This prevents any gas from backing up through the
line into the bay or the equipment room. This is especially important for ozone
units.
• The following should not be piped into the reclaim system: Domestic sewer
lines (sinks/toilets), regeneration from softeners, blowdown from compressors or
boilers, drains from service/ detail bays / areas where tire shine is applied.
• If self serve bays are to be piped into the reclaim tanks, a separate reclaim tank
should be used. Contact PurWater for details.
Important Note: Vent pipes from reclaim tanking should not terminate in the
equipment room oor or in the wash bay. Vents (typically) are above the water
line in the reclaim tank(s) and odors or possibly Ozone will exit the vents.
Any venting in the equipment room or wash bay should terminate outside -
typically at roof level to outside air.

also available.
For All PW050/100/200/300/350/400-5M Series Reclaim Systems
Frame
The system is to be installed in a clean, dry, temperature controlled and covered area.
It is not designed to be in the wash bay or outdoors. The “Gen 3” stainless steel frame
requires a oor space of 48” wide by 19” deep with a height of 81”. The “Xtreme” cabinet
requires oor space of 48” wide by 17” dep with a height of 68”. PW400 systems require
a oor space of 60” wide by 24” deep with a height of 77”. The system also requires a
minimum clearance of 18” along the sides, front and top of all frames to allow for routine
maintenance and inspection. The oor frame should be placed with its back along a wall
and should be secured to the wall to prevent movement of the frame. The area should be
free of excessive moisture which can cause extreme corrosion or electrical failure.

Piping
Fittings on these systems have some
“unionized” threaded connections
which are loosened prior to shipment.
There are two unions used on the
motorized ball valve on the inlet
piping, on the cyclone underow
piping, on the recirculation line, and
on the Mazzei eductor (for ozone
units) on the recirculation line. There
are also two unions on the underow
ush (U/F ush) motorized ball valve.
Re-tighten (Hand Tighten Only) all
union connections and any other
threaded connections prior to
introducing water into the system.
PurWater recommends using
Schedule 80 PVC for all connections
to the reclaim unit.

1. Treated Water Line
This line is to be connected to a manifold that feeds reclaim water to the wash equipment.
Valves need to be installed. Some are controlled by the wash controller. Some are
controlled by tank level (Ex: toilet bowl oat) when water is demanded by the wash. Do not
reduce the line size until reaching the wash equipment to prevent ow restriction
and pressure reduction. (See page 22 on direct feed concept for high pressure pumps.)
2. City Water Line
City water is to be connected, which will then provide fresh water for a bypass function to
the wash and the pump prime sequence. The city water supply line needs to be 1” for the
PW50 / 100 series and 2” for larger units to ensure enough pressure and ow are available.
City water should not exceed a pressure of 65 psi. High incoming city water pressure
can prevent the Prime and / or Bypass Valves from closing completely.

3. Recirculation Line
This 1” line provides a return line of treated water back into the reclaim tanking. The
Recirculation line output discharge in the tanking should be 3,000 gallons prior to the
suction line as shown on page 13. A solenoid valve (normally open) on this line closes only
during the pump prime sequence.
Air Sparger Units (Models ending in -5MAS) See photo below
The recirculation line is connected to the air sparger within the reclaim tank as shown
on page 12. (See below for air sparger assembly installation.)
Air Sparger Assembly
The air sparger assembly is installed into the reclaim tank (see drawings
page 12). It should be located so that it is accessible from the manway as
frequent inspection and maintenance are required.
Ensure the wall mount bracket is placed to allow the assembly to be removed easily.
The assembly consists of the air sparger, mounting brackets and inlet piping with a
union. The bottom of the sparger nozzle should be set 6-12” above the water
level and pointed downward. If this is not possible, mount the sparger horizontally
so that it sprays against a side wall. The top opening on the sparger body should

Ozone Units (Models ending in -5M04O-5M12O-5M24O)
The recirculation line is coupled in line with a Mazzei eductor. The Mazzei eductor
creates a vacuum drawing ozone from the ozone gernerating system. The line in
the tank should extend and terminate in a tee to split the ow in the tank (see page
13). The tee should be placed 20-24” o󰀨 tank oor or half of the water depth. An air
sparger is not / can not be used with an ozone system. All piping containing ozone
must be PVC. Rubber hose is not compatible with Ozone!! Ozone will eat
through rubber hoses and poly ow tubing.
PurWater System with Ozone
4. Pump Suction Line
Connect the suction line from the last compartment
of the last reclaim tank into the basket strainer inlet
on the reclaim unit. Keep the size of the line 2” for the
PW100 / 200 / 300 units and 3” for larger units. Piping
between the tank and reclaim system should have a
minimal amount of 90’s, threaded connections and
should never go higher than the basket strainer
inlet. The suction line within the Reclaim tank should
have a apper type foot valve at the very end of it and a
union installed for maintenance. Unions must be above
the water level to allow removal of the suction line from
the manway to access foot valves without draining the
tank. Unions must be tight to prevent suction loss. Do
not over tighten! PurWater supplies two PVC apper
check valves to attach to the suction lines. The bottom
of the valve in the tank should be a minimum of 16”
above the bottom of the tank oor. Do not use spring
loaded check valves or valves with screens on the
suction line. Pressure testing of both suction lines is
recommended before connecting to the reclaim unit.
Two suction lines are recommended. One is for use and
one is a spare. It is a real good idea to plumb the two
suction lines into a manifold during installation with ball
valves to facilitate making the switch from the primary to
the secondary suction line.

5. Underow Line
Connect the 1.5” line from the bottom of the cyclones to the catch basin or trench. An
underow ush (or U/F ush) motorized ball valve assembly is installed on this line
between two unions. This valve has a 5/32” hole drilled in it acting as an orice that passes
water owing from the manifold at the bottom of the cyclonic seperators. Once each day
at 2am the system will open the valve and ramp up the pump to ush the underow for one
minute. The pump will ramp back down to recirculation speed at the end of the cycle. The
underow line should be level or sloping downward to prevent solids build-up in the
piping or cyclones.

AquaLink (AOS)
The Gen 3 Reclaim is set up for simple and quick installation or retrot of the AOS-I or the
AOS-II system add-on. Plumb the system as follows: 1) Tape / thread the male adaptor
(supplied) to the recirculation line output as indicated in the picture. 2) Plumb from the
male adaptor to the AOS inlet port (top tting) 3) Plumb the AOS outlet port (bottom) to the
recirculation line “stub up” on the equipment room oor. There is no wiring required, simply
unscrew the black cover from the AOS receptacle and screw in the yellow cable from the
AOS control box (see photos below). Please note: There is a nder pin in the receptacle
and cable so there is only one way it will screw together. Verify that the pump runs when it
should. See the appropriate Aqualink Manual for more details!

Enhanced Trench Flush
The PurWater Enhanced Trench Flush has two purposes. The rst one is to wash down the Conveyor trench after the
wash activation to the reclaim has turned o󰀨. This will run for the duration set on the HMI touch screen. The second is to
turn the water over in the reclaim tanks overnight. Water will sit in the Conveyor pit and the rst couple reclaim tanks over
night not moving. This water will start growing bacteria (Anaerobic) over night and during the rst hour of washing the
water may have an odor. The program turns on the Enhanced Trench Flush every 30 min and runs it for 5 min aerating
the water owing in the tanks and turning the tanks over. The Enhanced Trench Flush timer is adjustable. The deration
between activation and the run time is adjustable (see picture of screen below). If this option is ordered the PurWater
Reclaim is Pre-built with a DIN cord for the solenoid connection for an easy connection once the hardware is installed.
Operation
The reclaim system will open the 1 ½” valve on the enhanced trench ush. During this operation, the reclaim pump
will maintain a line pressure of about 40 PSI. The water going through the valve will be fed down to a ball valve. This
ball valve is there to adjust water ow to the trench. With this ball valve open full you will get 45 GPM at 40 psi. A 1 ½”
Mazzei is after the valve to aerate the water. The Mazzei will pull 26.7 SCFM of air into the water stream. After the ush
turns o󰀨 the solenoid will close and the reclaim pump will ramp back down to its recirculation speed. If at any time a wash
activation turns on, the trench ush solenoid will close, and the reclaim treated water will be directed to the car wash.
After the wash activation is nished, the trench ush will turn on again for the set time. Detailed installation is included
when this option is purchased.
