Electrodeionization (EDI) ro system process :

Electrodeionization (EDI):

Overview: EDI is an advanced water purification process that combines ion exchange resins with electricity to remove ionized and ionizable species from water.

Ion Exchange Resins: Water flows through a series of cation and anion exchange resins that capture dissolved ions.

Electric Current: An applied electric field continuously regenerates the resins by driving captured ions out of the resin and into a waste stream.

Membranes: Selective membranes allow only certain ions to pass, further purifying the water.

Continuous Operation: Unlike traditional ion exchange systems, EDI does not require chemical regeneration, making it a more sustainable option.

 RO EDI system applications:

Pharmaceutical Industry:

Use: Production of ultrapure water for drug formulation and equipment cleaning.

Reason: EDI ensures the highest purity levels without introducing chemical contaminants.

Electronics and Semiconductor Manufacturing:

 

Source water tank → Feed pump→ Sand filter → Carbon filter → Softener →1st RO skid →Middle water tank → EDI device →DI water

 Deionized（DI）water system water deionizer inquiry guides

To find the most appropriate for your use, please advise the following information ready
· Product water flow rate ( m3/hr, m3/day, Liter/hr,GPM,GPD etc.)
·Product water purpose(drinking, irrigation, industry process or others)
· Feed Water TDS (Total dissolved solids). Is it from Borehole/salt/brackish/lake water
· Power (110/220/380V/415V/460V, 50 or 60 Hz) 3 phase.
·  It is necessary to make water analysis reprot for borehole water,lake water, seawater.
·  If soure water is tap water no need end to us TDS or water analysis report.
