Drinking Water Treatment--actived carbon filtration system
Activated carbon filtration can effectively reduce certain organic compounds and chlorine in drinking water. It can also reduce the quantity of lead, dissolved radon, and harmless taste- and odor-causing compounds. This guide discusses the principles, processes and requirements of activated carbon filtration systems for the domestic (household) user.
Quartz sand filter
Quartz sand filter can effectively remove suspended solids in the water by assorption,it can also effectively remove colloids, iron, organics, pesticides, manganese, bacteria, viruses and other pollutants ,the main advantage is with small filtration resistance. large specific surface area, strong resistance to acid and alkali , resistance to oxidation,.appicapable PH with 2 to 13 and strong pollution-resistance. As a unique advantages of the quartz sand filter, the filter is able to realize self-adaptively rworking by optmizing design on the filter media and filter, therefore the filter material has a strong adaptivity to raw water concentration, operating conditions and pretreatment process. i.e. that is,loose upper layer and density bottom layer status will be on the filter bed automatically during filtration, which ensures the good water output under a variety of operating conditions,the filter material will spread out during backwashing to achieve good cleaning effect.
The sand filter has some advantages,such as fast filtering speed, high filtration rating and large interception capacity on pollutant, etc. it is used in the industrial water, domestic water and municipal water systems which requires water output should be below 5mg/I in turbidity ,it is also applicapable to remove suspended solid sand solids in industrial or residential wastewater to complys with drinking water quality standards. it can be used in ion-exchange ,pretreatment for softening desalination system,coarse filtration for ordinary quality industrial supplying water, swimming pool circulating water treatment system and cooling tower circulating water purification system.
Activated carbon filter
Activated carbon filter is used for the remove color, taste, residual chlorine and organics mainly by adsorption. activated carbon is an artificial sorbent. Its cell-hole structure and huge superficial area, which has a strong adsorption capacity for the dissolved organics in the water, such as benzene and phenolic compounds.besides,
It shows strong removal efficiency for organic pollutants which is hard to be removed by biological and chemical methods, such as chroma, stench, surfactants, synthetic detergents and dyes, etc.Granular activated carbon material is able to remove 85% of Ag + , Cr2 + and Cr04-2 in the water .after the raw water flows through the activated carbon filter bed, the suspended solid in the water will be less than 0.1 mg/L, COD removal rate is generally 40% to 50% and free chlorine is less than 0.1mg/I. It can be used as pretreatment of ion exchange, electrodialysis and reverse osmosis in pure water technology so as to remove organics, colloids and residual chlorine; it can be also used as an advanced treatment method after the secondary treatment section to ensure the quality of reuse water.

Iron and manganese removal filter
Iron and manganese removal filter, filled with refined manganese sand and quartz sand, is used to remove iron and manganese in the water. It is applicable for the iron and manganese treatment of groundwater with iron content of less than 10mg/l and the maximum of no exceeding 15 mg/I and pH value below 5.5.A fter treatment by this filter, the iron content in the water could be below 0.3mg/I and the manganese content could be below 0.1mg/I, which meets the standards for drinking water, it is only used in the pretreatment section of raw water which contains iron and manganese content.
