Protective
filter
High
pressure
Reverse
osmosis
system
6.1.1 Drawing of process
Protective filter:
The filter Gross with a module B520-12 (CB) is installed at the entrance of the
installation to protect the RO membrane from influence of active chlorine. It is made
of sintered powdered activated carbon in a polymeric matrix (technology Carbon
Block).
The filter gross 20” with module PP5 micron is installed after the CB filter to prevent
particles larger than 5 microns to enter the RO system. Filter element is made of
polypropylene. It is necessary to replace regularly the filter modules in order to keep
the water feed rate, and also to avoid ingress of chlorine, solid particles in the
membrane modules
Replacement instructions: Shut off the system from electricity, make sure there is no
pressure (relief the pressure if needed), put a container under the system, with special
key open the housing of Gross. Remove the old module, pour the water. If necessary,
wipe the housing and the top cover. Install the new module. Set back the housing
vertically, tighten the nut of the housing by hand and gently close it with a key.
After replacement, inspect the modules by opening slightly the CIP valve , switch on
the system and close after a few seconds.
6.1.2 High-pressure pump
RO system can be equipped with pumps of different manufacturers and brands.
6.1.2.1 Instruction of operation
Install a pressure regulator to ensure the recommended pressure at the inlet of the RO
system, switch the pump to automatic mode. Automatic operation of the pump is
provided by water level sensors in the water feed tank, clean water tank, and the input

pressure switch.
6.1.2.2 Before starting the pump, unscrew the venting plug located on thetop
of the pump to release the air.
6.1.2.3 If the pump is used after a long period of shut down , firstly check
the free rotation of the fan motor, to ensure the it is not jammed due tocorrosion.
6.1.3 Installation of reverse osmosis.
Before installing the membrane, the piping must be flushed to eliminate the dust
formed during the installation, or other debris in the system with the high-pressure
reverse osmosis pump. Warning: direction of fitting the membrane strictly defined
and indicated by the arrows.
6.1.4 The principle of water purification reverse osmosissystem.
The system is set to use reverse osmosis membrane. With proper maintenance of the
RO system, the lifetime of the membrane is 3-5 years and over. RO system is based
on the method of membrane separation that allows to remove salt ions, organic
compounds, bacteria and other impurities from the water with the aim of purification
or desalting. It is based on the principle of separation of permeate (clean water) and
concentrate (dirty water) through the membrane. Water tends to get to a solution –a
process called osmosis. Between water and solution is the osmotic pressure. If the
solution is provided with more pressure than the osmotic pressure then permeate
(water) to be filtered through the membrane will not desalt the solution properly.
Thus, it takes desalting by reverse osmosis. With sufficient pressure, the raw water
passes through the RO membrane, and permeate as purified water. The concentration
of solutes and suspended particulates gradually increases and discharge to the drain.
This is the principle of operation of water purification by reverse osmosis system.
6.2 Technological drawing of the reverse osmosis system
Raw water passes through the protective filters, which allow to remove chlorine and
most of the suspended particles, and enters to the high-pressure pump, which builds
pressure up to 100-250 PSI (pressure required depends of the type of membrane).
Then, water is fed to the RO membranes under pressure. The RO membranes are
installed in the housings and produce separating permeate (product, i.e. purified water)
and concentrate (drainage).

7.3 Start-up
7.3.1 Start the pump of raw water and hold up a low pressure of at least 2 kg/ cm2.
Turn the switch of the system to manual control (CIP). Open the valves V-01 and RV-
01, but do not close completely valves RV-02 and RV-03
7.3.2 Pass water through the RO system for 10 ~ 15 minutes for removing air.
7.4 Security measures
7.4.1 In order to handle the RO system, you must be trained with the principle of
operation, design and operating rules and safetyguidelines.
7.4.2 The RO system is subject to all safety requirements of electrical equipment with
voltage 220/380B 50 Hz.
7.4.3 The RO system should be connected to a grounded powersource.
7.4.4 Do not open the electric control box or conduct manipulation with theelectrical
components of the RO system, while it isenergized.
7.4.5 It is forbidden to make any installation and/or change of the system whileit
works.
7.5 Commissioning
7.5.1 Prepare to work (carry out in manual mode):
New RO membranes are soaked with conserving agent. Before using them for the
first time , it must be thoroughly rinsed. Fully open valves RV-01 and RV-2,close the
valve RV-3. Start the raw water pump and high pressure pump. Achieve stable
operation of the pump, covering the valve RV-01 (When the high pressure pump is
working, do not close the valve RV-01 more than 2-3 times).
WARNING: Proper adjustment of the valve RV-01is needed to eliminate the effect of
cavitation. If you have no experience, do not attempt to configure the system, call for
service. Improper adjustment can lead to pump failure.
Make the system work for 30 minutes, then adjust the valves RV-01, RV-02 to ensure
proper operation and leave the system to work for 1 hour, while the permeate is
derived to the drainage.
7.5.2 Run the RO system:
After washing the membranes, slowly adjust the valve of concentrate RV-02 and
valve of recirculation flow RV-03, increasing the operating pressure up to 100-250
PSI (it depends of the type of membrane element).

WATER TREATMENT
Achieve the ratio of permeate and concentrate up to 70/30% (60/40, 80/20, etc.
depends on salinity, requirements for the quality of purified water, and the type of the
membrane element). The output capacity of the permeate should be ~ 125-375 liters /
h, and concentrate should be 180 to 540 l / h, depending on the model.
Attention: Depending on the raw water quality and the type of membranal elements,
the ratio of concentrate and permeate can be changed. The optimum ratio of permeate
and concentrate can be provided after a full water analysis in order to evaluate the
quantity of cations and anions of the dissolved salts.
If the flow of concentrate or permeate is not correspond to the values, adjust the
flows of valves RV-02 and RV-03. Changing the flows and/or increasing the permeate
flow will result in scaling, which will reduce the interval between the cleaning
treatment and reduce the life of the RO membranes.
7.5.3 Check the working pressure and compare it with the results of the first testand
the technical characteristics.
7.5.4 Check the presence of water at the outlet.
7.5.5 Check the system for leaks, remove them if necessary. Before working de-
energized the system, release thepressure.
7.5.6 Check the concentrate flow.
Note:After the start of operation, write the display values of the RO system, they can
help to predict the regulation for system maintenance.
7.6 Operation
7.6.1 Pressure and the degree of regeneration.
The system works at a design pressure. The operator must adjust the release valve of
the concentrate so that the operating pressure should be 100-250 PSI (depending on
the type of membrane), a maximum of 250 PSI and flow permeate should be 50-90%
of the feed water flow. Guided by the following principles:
7.6.1.1.1 Pressure in the system should not be more than maximumallowable.
7.6.1.1.2 The capacity of the concentrate will be in the operationrange.
7.6.1.1.3 Productivity for purified water (permeate) is calculated accordingto
temperature of raw water.
7.6.1.1.4 If the flow of permeate and total water consumption is reduced, system must
be flushed.
7.6.2 Replacement of membranes.

If the degree of demineralization is reduced after changing or servicing the reverse
osmosis membranes, it is possible if the membranes are damaged or installed not
correctly.
7.6.3 This RO system has the function of low pressure protection. If the pressure of
the raw water or water after the pre-filtration are below the minimum operating
pressure, the RO system will stop.
7.6.4 Never close the regulator of concentrate and\or the pump valve completely.
This will lead to a sudden increase of pressure and damage to the RO system.
Also the system will be under high pressure, it is not safe for servicestaff.
7.6.5 The conductivity meter installed on the purified water, allow you to see the
effectiveness of the ROsystem.
7.6.6 At the first start-up it is necessary to drain purified water to flush the ROsystem.
7.7 Maintenance operations at shutdown
7.7.1 Short shutdown (1 ~ 3 days)
When the ambient temperature is 5 ~ 35 ° C, you can turn off the system as a normal
shutdown. After turning the system on, the RO system should operate for at least 1 ~
2 hours.
7.7.2 Long shutdown period (more than one week) will require the followingsteps:
7.7.2.1 Soak the membranes in a 1% solution of sodiumbisulfite.
7.7.2.2 Soak the membranes in 0.5% formaldehyde solution (it is notrecommended
to use this chemical for installations operating in the food and medicalindustries).
7.7.2.3 If the ambient temperature is below 0 ° C, it is necessary to add antifreeze.
Sodium bisulfate 2%
Propylene glycol 40%
Clean water 58%
This solution passes through the RO system. Drain the liquid chemical agents in
conjunction with the flush water for 3 minutes. Stop the pump and close the RV-01,
RV-02 and RV-03 valves. This solution must be replaced after 2 months maximum. If
the shutdown period is more than 2 months, you must fill in a fresh solution.
7.8 Mode of operation
The unit has two modes –automatic and manual (CIP). Fully automatic operation is
operated by the RO controller, the water level sensor, the pressure sensor and the
TDS meter. In most cases the system is able to provide a continuous supply of water
automatically.

8. CONTROLSYSTEM
a.Control system and indication
RO system equipped with a switch system operating modes “AUTO” – automatic
mode, “OFF” – switch off and “CIP” – manual mode. Fully automatic operation is
operated by the controller. In most cases the system is able to provide a continuous
supply of water automatically. If necessary, it is possible to switch to manual mode,
eg; for flushing the membrane. It is necessary to switch from “AUTO” to “MANUAL”
or “CIP”. The switch “EMERGENCY STOP” de-energizes the entire electrical
circuit and is activated by turning in the direction of the arrows which is drawn on it
(typically clockwise). To re-power the RO system is necessary to press the switch
“EMERGENCY STOP”. To reset the conductivity controller in the case of
emergency stop, you need to press the "RESET" button.
b. Conductivitycontroller
Your system is equipped with a conductivity controller with the function of TDS
meter with temperature compensation mode, in the presence of the corresponding
conductivity sensor, on the screen the controller will display the conductivity of the
raw water in the “on-line”. The controller monitors the status of various sensors and
controls the operation of the RO system, based on the adjusting algorithm, the
standard for the majority of osmosis.
Visual screen display of the work process intuitively and immediately gives an idea
of the condition and operation of various modules of the RO system.
