1-Product Description

Reverse osmosis is the core technology of the seawater desalination plant. Seawater is pushed against a semi-permeable membrane that only allows water molecule to pass through at high pressure, while most of the salts present in the seawater is blocked, forming concentrated salt water which is returned to the sea. The seawater undergoes two stages of reverse osmosis to enhance salts removal.
The purified water can be used as process water without further treatment, drinking water after mineralization or make-up water for the boiler after further purification.

4-Replacement time of consumable parts

There are several kinds of consumables you need to replace regularly.
a. Quartz sand: replaced about every 15 months. 50kg/bag
b. PP Filter cartridge: replaced about every 1 month
c. Ro membrane: replaced about every 2 year
We suggest customers buy 1- 2 years of PP filter cartridges together with machine. Because these PP filter cartridges need to be replaced every month
