PURIFIED WATER

OSM/4000 DESALINATION BY REVERSE OSMOSIS

➢ Reverse osmosis membrane filtration whit operational pressure
max 50 bars. Desalinization process

Study of essential parameters of the osmosis process
The osmotic pressure of the water
The permeability of the membrane
The rejection and conversion rate of the reverse osmosis module

Optimization of a process of osmosis
Determination of the operational conditions ideal for attaching the
amount and quality of the permeate

The coil immersed in the tank allows a
constant temperature tanks to cool
water circulation.
5
The pump group can feed 4 the reverse 2 3
osmosis module 3 which is under
pressure. The rate of the solution
entering the membrane is limited by the
by pass circuit returning to the tank 1.

The filtration pressure and the permeate 1
rate are adjusted by the valves of the 4
supply circuit, the retentate circuit and 8
the bypass.
7
The permeate 5 and retentate 6 circuits,
in flexible tubes allow the storage of the
two solutions produced in two separate
tanks or the recycling to the tank Supply 1.
Other versions
Two valves on the outlet module enable sampling to follow the process
evolution via conductivity measurements. OSM/2000
Reverse osmosis Pressure 16 bar
In addition, the permeate line is equipped with online measurement.
