15000L/H Sand Carbon Security Micro PP Filter Pretreatment System Remove Impurities Color Chlorine

(1)Quartz sand principle

There is precise quartz sand in the quartz sand filter .During the raw water through the filtering layer ,

the impurity , suspended matter ,particles, colloids and other impurities etc .will be remove from the raw water .Then the water will be more clear and with lower turbidity.

(2)Activated carbon principle

Activated carbon is used shell (coconut) and other carbonaceous material made by chemical or

physical method activation. It has a very large number of pores and specific surface area, which has a

strong physical adsorption capacity, the effective adsorption of organic pollutants in water. Primarily to

remove organic matter in raw water, chlorine, odor, color, etc., so that the original residual chlorine in

water ≤ 0.1mg / l, effective protection of RO membrane from chlorine damage to parts of activated

carbon .

(3)Security filter

The security filter prevents the entry of particles, colloidal impurities, small suspended particles into 5

the intermediate tank .Security filter cartridge is made of polypropylene melt spray, with small resistance,

filtration speed characteristic. The filter cartridge should be replace regularly to ensure the inlet water

flow ,or the particles or impurities will flow into the RO part .The filter cartridge should be replaced

about every month .

How long the consumables should be replaced?

Strictly speaking, it depends on source water quality.

There is an approximate timetable for consumables replacement:
