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 20UM of substances hazardous to health.
Second stage pretreatment (Carbon filter)
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 (Sodium ion exchanger)
Soldium ion exchanger uesd for water softening, primarily to remove
hardness of water. So as to effectively prevent the reverse osmosis
membrane fouling. System can automatically recoil,
Fourth stage pretreatment (Precision 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.
