500lph EDI with 2 stage ro Ultra pure dialysis water system
Raw/feed/source water: city/tap/running water, ground water
Output water usage/application:for laboratory,battery water, hemodialysis water, Pharmaceutical industrial water,injection water basis,beverage company...
1.Technical Processes For ro+EDI System
(Water softener,dosing system,ozone generator or UV can be added if you need it. It depends on the quality of raw water )
raw water→raw water tank→raw water pump→sand filter+ carbon filter→security filter→high pressure pump→2 stage reverse osmosis system→ EDI→water supply points
2.What is EDI and how EDI works
EDI,also called electric desalination is a new ultra pure water technology which gradually developed
in the 20th century, which combines electric dialysis technology and ions exchange technology.
It is using the selectivity penerate function of anion and cation membrane and exchange
function of ions exchange resin, under direct current electric field to make ion directed migration.
Finally to make deep desalination of water. In the same time, hydrogen ion and hydroxide ion
which produced when water ionized will regeneration, and it can produce ultra pure water continuously

6.Advantages
1).System can produce water continuously, PLC/PC program controlled, Simple in installation and operation
2). RO system be chosen the import USA DOW membrane
3). Tank level control, automatic stop when the raw water tank without water or pure water tank is full
4). RO system flushes RO membranes when it starts to work so that membrane fouling is reduced.
5).CNP high pressure pumps or Denmark Grundofos high pressure pumps are adopted.
6). Product water quality is continuously monitored by conductivity meter.
7).Environmentally, will not cause any harmful pollution
7.Application
1). Electronic industry: Pre-filter for ultra pure water, chemical products and pure water
2). Food and beverage industry: filter for mineral water, wines and fruit juice, bottled drinking water
3). Medicine industry: filter for drug liquid
4). Chemical industry: filter for organic solvent
5). Petroleum industry: filter for oil-field flooding
