The desalination of seawater can be carried out by the following
Membrane separation and desalination/Membrane separation includes
(1) Reverse Osmosis process
Penetration is a natural phenomenon. The water in the lower
concentration of the solution passes through the semi permeable
membrane into the higher concentration solution until equilibrium
is reached; the reverse osmosis is the use of sufficient pressure
to allow the solution (usually water) in the solution to pass
through the reverse osmosis membrane A semi permeable membrane) and
the direction of the opposite direction of infiltration.
(2) Electro dialysis
Electro dialysis is the use of the characteristics of the current
to attract the dissolved ions. When the current is introduced into
the salt solution, the salt ions tend to adsorb on the opposite
polarity of the electrode. Electro dialysis is specifically used
for desalination of beach water. Heat treatment process is to
simulate the natural circulation, the water heated to produce
steam, and then through the condensation, as the product water
Main features of seawater quality
1. High salinity, generally about 35g / l
3. Lots of animals and plants in seawater
4. The composition of various ions in seawater is relatively stable
5. PH value changes very few. PH value of surface seawater is
between 8.1 and 8.3, deep seawater is about 7.8

There are several kinds of consumables you need to replace
regularly. (for 500LPH)
a. Quartz sand: replaced about every 15 months. 50kg/bag,100kg/set
b. Activated carbon: replaced about every 15 months. 25kg/bag,
c. Resin: replaced about every 15 months. 25L/bag, 50L/set
d. PP Filter cartridge: replaced about every 1 month. 2pcs/set
e. Ro membrane: replaced about every 2 year. 2pcs/set
We suggest you buy 1- 2 years of PP filter cartridges together with machine. Because these PP filter cartridges need to
replace every month.
A. Regulating wheels
B. PC Touch Screen
C. Two-stage RO system
D. PH adjustment
E. CIP cleaning system
F. Auto or manual control valve
G. U-PVC or stainless steel pipe
H. UV sterilizer/Ozone Generator
I. Dosing system(anti-scale)/Water Softener
J. PE or stainless steel raw/pure water tank
K. FRP or stainless steel pre-treatment tank
Process: raw water tank + raw water pump + quartz sand filter +
activated carbon filter + water softener/chemical dosing
system(optional) + security filter + high pressure pump + ro system
+ pure water tank + UV sterilizer(ozone generator) + precision
filter + water supply point
Some parts function:
1.Raw water pump: provide needed pressure for every pre-treatment filter;
2.Quartz sand filter: use fiber glass as housing, fill quartz sand, it can filter big
particles impurities, suspended substances, colloids etc. Important
to remove iron and sediments you mentioned;^^
3.Activated carbon filter: use fiber glass as housing, fill activated carbon, remove color,
odor, residual chlorine and organics substances;
4.Security filter: prevent large particles, bacteria, viruses into RO membrane,
accuracy is 5µm;
5.High pressure pump: provide needed working pressure for RO system, ensure production
capacity of pure water;
6.RO system: can remove particles, colloids, organic impurities, heavy metal
ions, bacteria, virus, heat source etc. harmful substances and 99%
7.Ozone generator(for bottled drinking): can continue to kill bacteria even water
fill into bottled,viruses,cell damage,atc...
Feed water(source water):
City water, river water, lake water, underground water(borehole,
well), brackish water, sea water......
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
3. Medicine industry: filter for drug liquid, gases
4. Chemical industry: filter for organic solvent
5. Petroleum industry: filter for oil-field flooding
