1. DEFINITION AND FUNCTION
1.1. WHAT IS REVERSE OSMOSIS?
The technic that is based on reverse osmosis is one that is based on an phenomenon that occurs in
nature.
Reverse osmosis (RO) is a membrane-technology filtration method that removes many types of
large molecules and ions from solutions by applying pressure to the solution when it is on one
side of a selective membrane. The result is that the solute is retained on the pressurized side of
the membrane and the pure solvent is allowed to pass to the other side. To be "selective," this
membrane should not allow large molecules or ions through the pores (holes), but should allow
smaller components of the solution (such as the solvent) to pass freely.
In the normal osmosis process, the solvent naturally moves from an area of low solute
concentration, through a membrane, to an area of high solute concentration. The movement of a
pure solvent to equalize solute concentrations on each side of a membrane generates osmotic
pressure. Applying an external pressure to reverse the natural flow of pure solvent, thus, is
reverse osmosis. The process is similar to other membrane technology applications. However,
there are key differences between reverse osmosis and filtration. The predominant removal
mechanism in membrane filtration is straining, or size exclusion, so the process can theoretically
achieve perfect exclusion of particles regardless of operational parameters such as influent
pressure and concentration. Reverse osmosis, however, involves a diffusive mechanism so that
separation efficiency is dependent on solute concentration, pressure, and water flux rate.

The incoming solenoid valve is opening / closing the raw water’s way, the rinsing valve
ensures the required water flowing speed during the membranes rinsing.
-Manometer
They are meant to indicate different pressures. They are filled with glycerine.
2.1.8. Control unit: takes care of the equipment’s automatic operation.
Selection of the control mode:
1. Manual or local operation mode: the equipment is not monitoring the tank’s level, it is
operating until the switch is in manual state
2. Remote or external signal: In case of remote control, we can allow or forbid the
equipment’s operation with an external switch. When allowing, the change in the tank’s
level will start or shut down the equipment. In case of forbidding, it will not take into
account the tank’s level, but it will execute the programmed rinsing cycle. Wiring diagram
can be seen under point eight.
3 Automatic: The change in the tank’s level will start or shut down the equipment. The
programmed rinsing cycle will be executed.

3. THE WAY IT WORKS
The basis of the operation is that water to be treated is led onto the semi permeable membrane
under high pressure. The molecules of the dissolvent (pure water) pass through the membrane
while the dissolved salts get trapped. The two solutions get led away permanently (pure solution-
permeatum, salt solution-concentrate) The purification of the water is done without chemical
processes, only on physical principals. However, to ensure long life of the membrane the water
needs pre-treatment. When starting the membrane it needs washing and periodical washing with
chemicals (at least every six months). Pre-treatment can be different:
- dosage of stuff obstructing crystallization: it obstructs the crystallization of CaCO3, CaSO4,
BaSO4, SrSO4, CaF2, SiO2, etc.
- softening with ion-exchange: it changes all the cations into Na+ ions, so there will be Na
salts that absorb in water,- meszes előlágyítás: csökkenti a membránt károsító hatásokat,
- pre-softening with lime: it decreases the effects harming the membrane,
- malfunction of the membrane caused by Fe, Al, bacteria, oxidizing material and organic
material can be decreased or eliminated by coagulation-floculation-filtration combinations
A thorough water analysis is required before the equipment is designed and built. After this we
can create the proper pretreatment and the most ideal membrane combination. This ensures long
service life and the highest possible output even with continous operation.
3.1. Working procedures:
during working of the application we differentiate the following stages
3.1.1. Water production:
In this stage inlet magnet valve is in open position. High pressure pump is in working
position. Controller checks conductivity of permeatum, pressure of inlet water and water
level of storage tank.
3.1.2. Stand-by stage
In this stage inlet magnet valve is in close position. High pressure pump is in stand-by
position. Controller checks permeatum tank pressure but does not check inlet pressure and
conductivity of permeatum. As pressure level reaches minimum controller starts water
production automatically.
3.1.3. Rinsing / washing stage

water treatment equipment manufacturer and wholesale distributor
BlueClear Industrial Reverse Osmosis Systems Page: 7
In this stage inlet magnet valve is in open position. High pressure pump is in working
position. Controller does not check pressure level in tank. Concentrate magnet valve is in
open position.
3.1.4. Out-of-order stage (closed main switch)
In this stage inlet magnet valve is in close position. High pressure pump does not work.
4. INSTALLATION AND STARTUP
4.1. INSTALLATION OF THE EQUIPMENT
There is not any special requirement for the site where applicaton is installed. Installation
has to be made on flat surface with concrete cover.
4.2. Climate circumstances
Application has to be installed in a place with temperature in range of +5°C and +40°C.
Treated inlet water temperature must not exceed +40°C-ot. Is is prohibited to install
application in dusted or high vapoured place. It has to be protected from freeze, heat, UV
stream. After installation application has to be connected to earlier built connection
points.
4.2 THE PROCESS OF THE EQUIPMENT’S INSTALLING
Before putting into the filter housing, the filter cartridge needs to be thoroughly washed.
The membranes have to be placed into the membrane housing with the marked direction, with the water’s
flowing direction. Please check the electronic connections and the pump’s spinning direction. The RO
controller needs to be adjusted according to the attached user’s guide.
Conduct a pressure test with the networking water pressure. Before it, by all means check the shut-off valve’s
position. In order to fully fill the equipment with water, first we have to air-bleed the system, after that on
the RO’s outlet every shut-off valve have to be in CLOSED state and on every inlet (raw water) shut-off
valve have to be in OPEN state.
After the succesful pressure test, switch back the shut-off valve’s state to the starting state. Set the valve that
is after the high pressure pump to half open state. Set the concentrate regulator’s valves to half open state.
Outflow has to be ensured for the permeate. Please set the raw water’s valve to OPEN state.
Check the raw water’s pressure. After the 0,5 micron filter cartridge the water pressure has to be minimum 3
bar. Set the pressure-mushroom to the value of 3 bar.
Start the RO equipment with turning the main switch and set the control mode switch to manual state. With
the help of the concentrate regulator valve set the permeate to 50%, and the concentrate to 50%. During this,
continuously check the pressure. Aim for a pressure level, which equals the value on the membrane’s data
sheet depending on the given water’s parameters. In case of the RO equipment’s permeate ratio is less than

Tel: [phone] • E-mail: [e-mail] • Web: www.euro-clear.eu
Euro-Clear Kft.
water treatment equipment manufacturer and wholesale distributor
BlueClear Industrial Reverse Osmosis Systems Page: 8
50%, please in 2-3 steps set the permeate’s ratio to above 50%. Between the steps keep a 10-15 minute break,
to let the equipment get back to it’s balanced state.
After we finished setting the permeate rate and pressure, check the outflow water’s conductivity. It is
important that the membranes could take hours till they reach the required conductivity level.
Ater installing the equipment in manual operating mode, switch the controlling mode selection switch to
automatic state. Check if the permeate tank’s level switch starts and shuts down the RO equipment
appropriately. Check if during starting and shutting down the membranes automatic washing works as
intended. In case of continuous membrane usage the maximum value to set the washing on the RO’s
controller is eight hours.
Turn off the main shut-off valve, turn off the main switch.
Train the operator staff.
With filling the installation log and signing the equipment’s take-over record, hand over the equipment to the
operator.
Please pay extra attention to appropriate training of the RO equipment’s operators and for the appropriate
filling of the operating log.
Please read the user’s guide carefully, and follow it’s instructions.
IMPORTANT!
During startup, in the beginning lower the capacity/yield to 50%, and slowly in 3-5% steps,
this will be increased to the max capacity/yield. Between some steps take a 12-15 minute
break, to let the equipment balance itself out. Only execute the next change after the break
is over.
4.3. THE EQUIPMENT’S STARTUP
After the startup, the open the main shut-off valve and check the incoming water pressure
on the RO equipment prefilter’s (0.5 micrometer) manometer. This has to be min. 3bar and
max 6 bar.
Turn on the main switch. Of course the equipment will only start if the feed tank’s level
controller will require water or if we set the control mode selector switch to local state.

Check if the equipment’s pump regulator’s valve and concentrate regulator’s valve
are in the adjusted position at startup. During startup the equipment’s valves are
adjusted by the manufacturer’s expers with the goal of optimal outcome. Changing
these settings of the valve can lead into loosing your warranty.
ATTENTION!
Exceeding the prescribed values like the quantity of permeate, pressure or outcome may
lead into membrane errors. And ultimately, it can lead into loosing waranty.
