Automatic EDI Water Treatment Plant / Plant / Line Prices
Environmental value editor
The most important feature of EDI technology is the chemical
regeneration of ion exchange resin by
electric field and ion membrane, which makes RO-EDI pure water
system have obvious advantages
compared with RO2 mixed bed in terms of equipment structure,
operation and operation cost; Wastewater
discharge problems caused by recycled resins.
(1) EDI and RO are used together to adjust the current to change
the quality of the water. The
standard module combination is used to change the water output.
More than ten years of commercial
application shows that the system operates stably at a pressure of
100 psi (7 kg/cm2), the effluent
resistivity can reach 16 M8·cm or more, and the Si content is below
20 ppb. The water quality is reliable
and can meet the current maximum. Strict industrial water quality
requirements, water output can be as
high as 2000 gallons / min (450 cubic meters / hour).
(2) EDI does not use recycled resin, eliminating the need for resin chemical recycling facilities
(such as
acid and alkali storage tanks, pumps and pipelines) to simplify the
structure of pure water system
equipment, save investment, simplify operation and reduce operating
costs.
(3) The technical and economic comparison also shows that EDI is more adaptable to the change of TDS
in the influent than the mixed bed system without affecting the
quality of the effluent, and has little effect
on the cost of water production.
(4) EDI environmental benefits are significant, in two aspects: 1 overcome the wastewater pollution caused
by resin chemical regeneration; 2EDI discharged concentrated water
can be directly used before
returning to RO, so that EDI unit can achieve no wastewater
discharge. [1]
