SUS304 SS Water Purification Machine Strong Adsorption Capacity Of Activated Carbon

Technology instruction:
 
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.
