250lph EDI with 2 Stage RO Ultra Pure Dialysis Water SystemWORKING
PRINCIPLE OF EDIULTRA-PURE WATER TREATMENT EQUIPMENT
EDI-electrodeionisation system is a scientific water treatment
technology, in which dielectric ions in water passing through the
partition move directionally under the action of DC electric
field,and water quality is purified by selective permeation of ions
by exchange membrane. Between a pair of electrodes of
electrodialyzer, a plurality of groups of negative membranes
positive membranes and separators(A and B) are alternately arranged
to form a concentrated chamber and a weak chamber(i.e,cations can
pass through the positive membrane and anions c an pass through the
negative membrane).Cations in the light chamber water migrate to
the negative electrode and pass through the positive membrane,and
are intercepted by the negative membrane in the concentrated
chamber;Anions in the water migrate to the cathode direction and
are intercepted by the anode membrane in the concentrated chamber,
so that the number of ions in the water passing through the light
chamber gradually decreases and becomes fresh water while the
concentration of dielectric ions in the concentrated chamber
continuously rises due to the continuous influx of anions and
cations in the concentrated chamber, and becomes concentrated
water, thus achieving the purpose of desalination,purification,
concentration or refiningAPPLICATION FIELD OF EDI ULTRA-PURE WATER
TREATMENT EQUIPMENT 1. Chemical water treatment of power plant2.
Ultra-pure water in electronics,semiconductor and precision
machinery industries3. Preparation of food,beverage and drinking
water4. Small pure water station group drinking pure water5. Water
use for fine chemicals and sophisticated disciplines6. Preparation
of high-purity water required by other industries7.Process water
for pharmaceutical industry8. Desalination of seawater and brackish
water Advantages of EDI Technology1.Best stability of water
quality2.Constantly produce ultrapure water as per user
requirements3.Modular production, can achieve automatic control4.No
need acid and alkali regeneration, no pollution emissions5.No need
stop because of regeneration6.No need regeneration equipment and
chemical storage7.Compact equipment, small size8.Low operation and
maintenance cost9.Simple operation and low labor strengthEDI
systemEDI, also known as electric desalination. It is a new
ultra pure water technology which gradually developed in the
20th century. EDI equipment combined electro dialysis
technology and ion exchange technology. It is using the selectivity
penetrate function of anion and cation membrane and exchange
function of ion 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 ionize will regenerate ion exchange resin. So
if use EDI equipment, no need acid and alkali chemical to do any
regeneration, and it can produce ultra pure water
continuously.Process Raw water tank(user supply) → raw

water tank(user supply) - outlet Main parts
function1. Raw water pump-- provide the pressure to quartz sand
filter/active carbon filter/softener.2. Multi-medium filter--get
rid of turbidity, suspended matter, organic matter, colloid, etc.3.
Active Carbon filter--Remove the color, smell, free chloride,
organic matter, harmful matter, etc.4. Softener--exchange "ions" of
calcium and magnesium with the most common and easiest method.5.
Security filter--prevent large particles, bacteria, viruses into RO
membrane, accuracy is 5um,6. High pressure pump--Provide the high
pressure to RO membrane.7. RO system-- main part of the plant. The
RO membrane's desalting rate can reach 99%, removing over 99%
ions.Q: Are you trading company or manufacturer ?A: Yes, we are
a manufacture with designing, manufacturing, marketing and
exporting.Q: What's the information you need to know before
order?A: what's your raw water ?B: what's the capacity per hour of
