Easy maintenance and cleaning
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. The
effluent turbidity is less than 0.5NTU, CODMN less than 1.5mg / L,
iron content of less than 0.05mg / L, SDI less than or equal to 5.
Water filter is a kind of "physical - chemical" process, the water
through granular materials when isolated filter water impurities
and colloidal suspensions. Filter is an effective water
purification and treatment of the main process in the preparation
of pure water is an indispensable process.
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. The structure of activated carbon filters
and quartz sand filters, the difference is placed inside the strong
adsorption capacity of activated carbon for removal by the quartz
sand filter without the filter out organic material, adsorption of
residual chlorine in the water, using water more than less than or
equal to chlorine 0.1ML/M3, SDI less than or equal to 4, are strong
oxidants chlorine, there are various types of membrane damage, in
particular, reverse osmosis membranes are more sensitive to
chlorine. In addition, the activation process, the surface of
activated carbon to form non-crystalline parts of some
oxygen-containing functional groups, these functional groups can
have a chemical adsorption of activated carbon catalytic oxidation
of bad news, to restore the performance, can effectively remove a
number of metal ions in water.
Third stage pretreatment (Resin softener)
Cationic resin used for water softening, primarily to remove
hardness of water. The hardness of water is a major calcium (Ca2
+), magnesium (Mg2 +) ion composition, when containing the raw
water hardness ions through the resin layer, the water of the Ca2
+,Mg2+ was exchanged resin adsorption, and other objects at the
same time the quality of the release of sodium Na + ions flow from
the softener in the water is removed from the softened water
hardness ions. 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, but still per milliliter of water for
hundreds of thousands of particle size 1-5 microns colloidal
particles, the pressure on this filter to remove water after the
particle size of 100 microns or less in small particles, to
further reduce the turbidity, to meet the next process of the water
requirements of the protection of the next long-running
Using reverse osmosis technology for desalination, reverse osmosis
membrane was only 0.001 micron pore size, can be harmful to remove
dissolved solids and bacteria, viruses, etc., desalination rate of
more than 99.6 percent, in line with national standards to produce
pure water, the host section contains the security filter,
high-pressure pump and reverse osmosis membrane, security filters
for the fourth grade and above pre-treatment systems, high-pressure
pump is the host of one of the core equipment for the reverse
osmosis membrane elements to provide sufficient pressure to
overcome the penetration resistance to pressure and run to meet the
needs of a device to achieve the rated water.
