First stage pretreatment (Sand filter)
：The use of multi-medium quartz sand filters, main purpose is to remove the water contains sediment, manganese, rust, colloid material, mechanical impurities, suspended solids and other particles in the above 20μm of substances hazardous to health.
|
|
|
|
|
||||
|
Second stage pretreatment (Carbon filter)
x2
：Activated carbon filters used to remove the pigment in the water, smell, a large number of chemical and biological organisms, reducing the residual value of water and pesticide pollution and other harmful pollutants.
|
|
|
|
|
||||
|
Third stage pretreatment (Resin softener)
：Cationic resin used for water softening, primarily to remove hardness of water. So as to effectively prevent the reverse osmosis membrane fouling. System can automatically recoil, and so is red.
|
|
|
|
|
||||
|
Fourth stage pretreatment (Micron filter)
：Particle size in water to remove fine particles, sand filters can remove very small colloidal particles in the water, so that the turbidity reached 1 degree.
|
|
|
|
|
||||
|
RO system
：The core equipment of water pump is imported and the membrane film is imported from Hydranautics in America. It is equipped with full set of clean unit. It has the features of simple structure, convenient operation and high technological level.

Some parts function for your reference as below^^:
|
|
|
|
|
||||
|
Manganese sand filter:
fill manganese sand inside, it can iron(Fe2+), manganese(Mn2+) ion in water etc.
|
|
|
|
|
||||
|
Quartz sand filter:
fill quarts sand inside, it can filter big particles impurities, suspended substances, colloids etc.
|
|
|
|
|
||||
|
Activated carbon filter:
fill activated carbon inside, to remove color, odor, residual chlorine and organics substances
|
|
|
|
|
||||
|
Water softener(Chemical dosing system):
adopt cation resin to soften wate/add antiscalant(buyer supply) , absorb Ca2+, Mg2+(main elements for composing scale), reduce hardness of raw water.
|
|
|
|
|
||||
|
PH adjusting system:
to adjust the PH data
|
|
|
|
|
||||
|
Security filter:
fill cation resion inside, prevent large particles, bacteria, viruses into RO membrane, accuracy is 5um.
|
|
|
|
|
||||
|
RO membrane:
can remove particles, colloids, organic impurities, heavy metal ions, bacteria, virus, heat source etc. harmful substances and 99% dissolved salts.
|
|
|
|
|
||||
|
EDI membrane:
ultrapure water, output conductivity less than 0.2uS/cm
|
|
|
|
|
||||
|
UV sterilizer(ozone generator):
for killing bacterial in water, be safe for drinking.
|
|
|
|
|
||||
|
CIP system:
its help to cleaning the RO membrane, so that it can be have long life span^^
