Filters

Installation:
Raw water pump +quarts sand filter + active carbon filter + resin softener system + micron filter+RO system

1.0 Water feeding pump
Requested access to the system& acute;s raw water has a stable flow and pressure, its purpose is to prevent water fluctuations have an impact on the system operation to ensure the stability of the system into the water.

1.1 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 & quot;physical - chemical& quot; process, the water through granular materials when isolated filter water impurities and colloidal suspensions.

1.2 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.
