Reverse Osmosis Membrane 4021
Description
Puran RO membrane elements are produced with Japanese sheets. It is used for the desalination of high salinity water and other similar water. It has high salt rejection rate, stable performance and high flow rate working at low pressure. It is used to produce pure water or ultra-pure water in fields of electronics, power, petrochemical, food, beverage and pharmacy.
Features
Ø Japanese membrane sheet
Ø High silica and hardness rejection
Ø High permeate flow rate
Ø Low operating pressure
Ø Stable performance with long life.

* The limitations shown here are for general use. Operating at more conservative values for specific projects may ensure the best performance and longest life of the membrane.
Test Condition
The stated performance is for the initial data taken after 30 minutes of operation, based on the following test conditions:
Note
Permeate flow for individual elements may vary +25% or -25%. All membrane elements are supplied with a brine seal, interconnector, and o-rings. Elements are enclosed in a sealed polyethylene bag containing less than 1.0% sodium meta-bisulphate solution and 10% propylene glycol, and then packaged in a cardboard box.
