Reverse osmosis seawater desalination equipment to conduct a preliminary deal with seawater first , and then lower the water turbidity, prevent bacteria , algae and other microorganisms. With special high-pressure pump pressurized seawater into the reverse osmosis membrane , due to the high salt content of seawater , seawater reverse osmosis membranes and therefore must have a high salt rejection rate , corrosion resistance, high pressure , anti-pollution , etc. After the reverse osmosis membrane treatment seawater , its salinity is greatly reduced , TDS content from 36,000 mg / l to 200 mg / l. Water quality is better than tap water after desalination , so industrial, commercial , residential and cruiser , ship is all of available for use .

EDI is a revolutionary technology for the water treatment .This technology uses the demineralization process of electrical regeneration ion exchange instead of traditional demineralization process of mixed ion exchange DI .The resin and selective ion membrane can reach high desalination effect by exchanging the ion ,and if the process is combined with reverse osmosis ,the water quality can be up to 15-18 Mn.CM

EDI uses the standard modules in design and can be assembled into arbitrary system according to the requirement ,water output can be up to 0.5-60M3/H

Feature of EDI

No salt needed

EDI does not consume salts in operation and need much lower operating expenses. So EDI does not need recycle the concentrate ,which makes the system much simpler. EDI without salt, reduce the operating cost.

Counter flow

Concentrate and electrolyte stream flowing into EDI in opposite directions can avoid fouling largely. Then it broadens the feed water limit adequately.

Low energy consumption
The unique chambers design make the EDI consume lower energy. EDI fully filled with resin make the EDI module resistivity significantly reduced, which makes the energy consumption save largely.

High quality material and components
EDI put high quality ion-exchange membrane into use ,which has high exchange capacity and high selectivity. Appropriate degree of resin compaction makes the resin ion migration efficiency.
