1.0 Principles of Reverse Osmosis
The heart of the system is a semi-permeable membrane that will allow small molecules to
pass through, such as water (H2O) and reject larger molecules such as sodium Chloride
(NaCl). At atmospheric pressure, if a membrane separates two of different solution strengths,
ions from the stronger solution tend to flow into the weaker solution until equilibrium is
attained.
As the name suggests, “Reverse Osmosis,” reverses this natural tendency by exerting an
“Osmotic pressure” on the membrane.
Now the concentrated side of the membrane forces the smaller water molecules through the
membrane to the permeate collection manifold. The concentrated water becomes more
concentrated and the diluted water becomes more pure.
The most important aspect of reverse osmosis operation is to ensure the raw feed is correctly
treated to prevent fouling and possible irreversible damage to the reverse osmosis
membrane.
2.0 Pre Treatment
Rarely, in fact, almost never is water suitable for direct entry to the membrane housing.
Table 1 shows a number of contaminants present in raw water capable of causing a
permanent damage to the membranes. Please note these are the main contaminants.
However, other salts or metals may be encountered and would require a specific treatment.

4.0 Process Description and System Components
4.1 General Process
This is to be read in conjunction with the General Arrangement drawing (Figure 1).
The raw water is pre treated before entering the KRO3000. The first stage of pre treatment is a
water softener which eliminates hardness to prevent scaling problems.
The softened water flows to a carbon filter to remove the chlorine which is detrimental to RO
membranes. Following the carbon filter the water passes through a 5 and 1 micron filters
arrangement to remove suspended material.
Filtered water is pumped via a high pressure (boost) pump through the RO housing, containing
the membrane. Permeate (treated water) is sent to a break tank and the Reject (brine) is sent to
the drain.
A Recycle line is also provided, this line goes from the reject line to the pump suction line. The
purpose of the recycle is to create a hydraulic equilibrium, correct recovery rate and system
pressure.
The system is completed with an inlet solenoid valve. This valve automatically turns off the water
supply between the feed water and the membrane. A level control inside the tank sends a signal
to the valve to close when the tank is full. Once the level in the tank is low, the level control sends
another signal to the solenoid valve to permit the flow of raw water into the system. Every time
the valve opens/closes the system will start/stop automatically.
A Flush solenoid valve is also provided with the unit. This valve is under the control of a timer.
Periodically the valve opens to flush the membrane at low pressure. This extends the periods
between membrane cleans.
4.2 System Components
4.2.1 Water Softener
The water is Hard when Calcium and Magnesium are dissolved in it. These salts precipitate out of
the water causing scaling problems. To prevent this situation the water is pre treated using a
water softener.
Raw water flows through a media (small plastic beads or chemical zeolite) covered in sodium
ions. The calcium and magnesium ions are replaced with sodium ions. As sodium does not
precipitate out of the water, the scaling problem is eliminated.
However, the media is exhausted after certain amount of water has been treated. This is because
no more sodium ions are available to swap places with calcium and magnesium. Consequently,
the media needs to be regenerated.
The regeneration process is very simple. The media is soaked with a Sodium Chloride (brine
tank) solution. The sodium ions change places with the calcium and magnesium trapped in the
media. In this way the media is being regenerated and is ready to exchange the sodium ions
again. The remaining brine plus all of the calcium and magnesium is flushed through a drain.
The regeneration cycles on the KRO3000 systems are programmed based on the hardness of
the inlet water.

Caution: THE SALT USED FOR REGENERATION OF THE WATER SOFTENER MUST BE
“CROWN HG WATER SOFTENER SALT”. NO OTHER SALT CAN BE USE FOR
REGENERATION.
4.2.2 Carbon Filter & Cartridge Filters
The carbon filter is designed to remove the chlorine from the water. Cartridge filters are designed
to remove suspended material greater than 5-Micron @ 1-Micron prior to the pre treated water
flows into the membrane. This protects the membrane from significant colloidal contamination.
The cartridges should be renewed every 4 months, as minimum. If the raw water is significantly
polluted then the cartridges should be changed in a shorter period of time.
Caution: It is EXTREMELY important to renew the cartridges. Mainly the carbon filter. If
any trace of chlorine goes into the housing, the membrane will be permanently damaged.
4.2.3 High-Pressure Pump
High-pressure pump is one of the key components, to boost the pressure for correct membrane
operating conditions.
4.2.4 RO Membrane Housing
RO membrane housing is to guarantee the RO membrane can work under the conditions of
normal pressure and seal arrangement.
Caution: The operator should apply silicon grease on the “Y’ type plastic ring in order to
ensure proper sealing of the membrane brine seal.
4.2.5 RO Membrane
RO membrane is the key component of the RO main unit and has a determinative effect on the
quantity and quality of water produced. The RO membrane utilizes pressure-energy to separate
larger contaminant molecules from the body of water.
For a given Temperature, Pressure and feed Total Dissolved Solids (TDS), if the quantity of water
produced decreases by 10%, please consult your supplier of the unit.
4.2.6 Conductivity Monitor
The function of conductivity monitor is to measure conductivity condition of the permeate water.
Caution: Please do not clean with strong acid and strong alkali to prevent the electrodes
from being damaged.
4.2.7 Reject Control Valve
The main function of the reject valve is to adjust the reject flow from the membrane. Adjust the
reject valve to attain the correct recovery rate and systems pressure in conjunction with the
recycle valve.
Caution: Please do not turn off the reject valve. The high pressure in the membrane
housing may cause irreversible damage to membrane and/or housing.

4.2.8 Recycle Control Valve
The main function of the recycle valve is to adjust the flow from the membrane brine port to the
booster pump suction. Adjust the recycle valve to attain the correct recovery rate and systems
pressure in conjunction with the reject valve.
Caution: Please do not turn off the recycle valve. The high pressure in the membrane
housing may cause irreversible damage to membrane and/or housing.
4.2.9 Flush Solenoid Valve
The flush solenoid valve is under the control of a timer. Periodically the valve opens to flush the
membrane at low pressure. This tends to extended the periods between membrane cleans.
4.2.10 Rotameters
Rotameters are provided to indicate the permeate and reject flow rates
4.2.11 Pressure Gauges
Pressure gauges are provided to monitor operating conditions and facilitate the adjustment of the
recycle and reject valves
4.2.12 Low-Pressure Switch
Low-pressure switch is a safety device that in conjunction with the controller shuts down the unit
in the event of low feed pressure.
4.2.13 Float Switch
.A facility is provided to connect an external float switch in the permeate storage tank. When the
circuit is broken between the, “HIGH-LEVEL,” contacts (no volt) the unit automatically stops. The
unit will remain on standby until the level in the tank drops, remaking the circuit.
4.2.14 Pressure Reducing Valve (PRV)
If no break tank and set pump is available for the raw water supply, then a PRV is provided to
guarantee the correct operating feed pressure going into the system. The PRV also protects the
unit from over pressure situations that may cause damage to the equipments.
The feed pressure must be between 250 to 500kPa.
5.0 Installation Guide
Installation Environment and Technical Requirements
5.1 The operator should install the unit in a covered dry place, shielded from the elements to
protect the electrical components and equipments generally from damage and
premature deterioration.
5.2 Sufficient room should be allowed to conveniently operate and service the unit.

1.2 Installation
All plumbing and electrical connections must conform
to local codes.
Inspect unit carefully for carrier shortage or shipping
damage.
Location Selection
1. Thedistancebetween theunitandadrainshouldbe
as short as possible.
2. If it is likely that supplementary water treatment
equipment will be required, make certain adequate
additional space is available.
3. Since salt must be added periodically to the brine
tank, the location should be easily accessible.
4. Do not install any unit closer to a water heater than
a total run of 10 feet (3 m) of piping between the
outlet of the conditioner and the inlet to the heater.
Water heaters can sometimes overheat to the
extent they will transmit heat back down the cold
pipe into the unit control valve.
Hot water can severely damage the conditioner. A
10-foot (3-m) total pipe run, including bends,
elbows, etc., is a reasonable distance to help
prevent this possibility. A positive way to prevent
hot water flowing from heat source to the
conditioner, in the event of a negative pressure
situation, is to install a check valve in the soft
water piping from the conditioner. If a check valve
is installed, make certain the water heating unit
is equipped with a properly rated temperature
and pressure safety relief valve. Also, be
certain that local codes are not violated.
5. Do not locate unit where it or its connections
(including the drain and overflow lines) will ever be
subjected to room temperatures under 34oF (1oC)
or over 120oF (49oC).
6. Do not install unit near acid or acid fumes.
7. The use of resin cleaners in an unvented enclosure
is not recommended.
Water Line Connection
The installation of a bypass valve system is
recommendedtoprovideforoccasionswhenthewater
conditioner must be bypassed for hard water or for
servicing.
The most common bypass systems are the Autotrol
Series 1265 bypass valve (Figure 1.1) and plumbed-in
globe valves (Figure 1.2). Though both are similar in
function, the Autotrol Series 1265 bypass offers
simplicity and ease of operation.

Drain Line Connection
Note: Standard commercial practices are expressed
here.Local codesmayrequire changesto thefollowing
suggestions.
1. Ideally located, the unit will be above and not more
than 20 feet (6.1 m) from the drain. For such
installations, using an appropriate adapter fitting,
connect 1/2-inch (1.3-cm) plastic tubing to the drain
line connection of the control valve.
2. If the backwash flow rate exceeds 5 gpm
(22.7 Lpm)or if the unitis located more than 20 feet
(6.1 m) from drain, use 3/4-inch (1.9-cm) tubing for
runs up to 40 feet (12.2 m). Also, purchase
appropriatefittingtoconnectthe3/4-inchtubingto
the 3/4-inch NPT drain connection.
3. If the unit is located where the drain line must be
elevated, you may elevate the line up to 6 feet
(1.8 m) providing the run does not exceed
15 feet (4.6 m) and waterpressure at conditioner is
not less than 40 psi (2.76 bar). You may elevate an
additional 2 feet (61 cm) for each additional
10 psi (0.69 bar).
