Ultra-pure water treatment system,EDI

EDI Water Equipment Device 
RO and combine technique 
Standard Design 
Automatic Operation

EDI is a technology for the water treatment.

EDI advantage:

1.                     Continuous production

2.                     Convenient operation and management

3.                     No need for acid and alkali regenerating

4.                     Without the emission of acid and alkali solution

5.                     Stable quality of output water

6.                     Low woking cost

7.                     Standard design

8.                     Compact structure

Process : Raw water→The raw water tank→Booster Pump→Quartz sand filters→Activated carbon filters→Scale inhibitor charging equipment→ultrafilter→High pressure pump→Scale inhibitor charging equipment→CO2 deaerator→midst water tank→midst water pump→EDI device→Ultrapure water

This technology uses the  demineralizaion process of electrical regeneration ion exchange instead of traditional demineraliazation 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 10-15MΩ.

EDI uses the standard  modules in design and can be assembled into arbitary system according to the requirement,water output can be up to 1-450m³/h.

The supplied raw water enters into EDI system,man portion flows into resin/membrane,and the other portion flows along the outboard of the menbrane plate,in order to the ion outside the membrane.

Resin captures undissolved ion.

The captured ion is forced by the elctrode,anion moves to anode,and cation moves to cathode.

Cation permeates cation membrane,and discharges from resin/membrane.

Anion permeates anion membrane,and discharges from resin/membrane.

Concentrated ion  discharges from the wastewater flow channel.

Non-ion water discharges from resin/membrane.
