Product Description

 Automatic Back Wash Industrial Sand Filter For Water Treatment


Working Principle

Quartz sand filter 

is one of the main equipments of the deep treatment of the water , and the selection of filter material generally is quartz sand or activated carbon.It is widely used for water pretreatment,such as, pure water, drink water in food, mineral water and water in electronics,printing and dyeing, papermaking, chemical industries, and it is also used to filtrate industrial wastewater after secondary treatment . And it is used for deep filtration of water reuse system and water treatment system of swimming pool. There is  very good removal effect on suspended solids in industrial wastewater.


Compared with other products, the products and water purifier of our company have the advantages of long using life, low energy consumption, good effect and the following characteristics:

The device has simple structure and it is convenient to operate and maintain; The operation can realize the automatic control, high filtration efficiency, small resistance, large processing flows,less fequency of recoil.There is two washing systems: gas washing and water washing and it has the function of putting an end to short flow.

With a carbon filter process, water passes through activated carbon which is porous, trapping certain particles that are attracted to the porous material. The size of particles attracted depends on the size of the pores or micron rating. However, not all particles are attracted to the active carbon filter.

And at some point it loses its ability to attract particulates and must be changed in order to be effective.


In the process of filtering water, activated carbon is often used to remove contaminants and impurities. Carbon is probably the most absorbent material known to man, and it is uniquely efficient because of thousands of tiny pores that can absorb. For example, a pound of activated carbon provides 125 acres of filtering surface area. The carbon is positively charged to attract negatively charged impurities such as chlorine, chemicals and volatile organic compounds.

Most carbon water filters are either made with granular activated carbon (GAC), or powdered block carbon material. Those with carbon block are the most effective, since there is a larger ratio of activated carbon surface area to water, and also because the powdered block form is denser and water travels through it more slowly. The larger surface area created by the block carbon, and the more time the water is in contact with the carbon, the more contaminants are removed.


The multi-media filtration water treatment equipment    mainly takes the quartz sand,blind coal and so on as the filtration medium to remove the suspended solids,mechanical impurities,organics and to lower the turbidity of the water. 


The active carbon filtration water treatment equipment mainly   takes the active carbon as the filtration medium to absorb & remove the pigment,organics,residual clorine and colloid etc in the water.


The manganese sand filter   mainly takes the natural or synthetic manganese sand as the filtration medium to remove the divalent iron ions,manganese ions in the water and to lower the turbidity of the raw water 



The multi-media filter

It is able to remove the big suspended solids, lower the water SDI,meet the requirement for the deep purification water;

advantages:cost saving;lower operating expense;easy to operate;the filtering media can be used repeatedly after backwashing;long service life 

The active carbon filter

High efficiency;lower operating expense;lower maintaining charges;lower one-time investment;lower head loss;lower requirement for inflow water quality;stable effluent quality;brilliant filtration,easy to reorganize & expand,smaller land covering,good appearance

The residual clorine in the water after being filtered by active carbon filter is no more than 0.1PPM

The performance to remove the odar,organics,colloid,iron and residual clorine is outstanding;

It's conductive to lower the turbidity,chroma,water quality purification and to reduce the pollution to follow-up systems

The manganese sand filter

Smaller filtration resistance,the specific surface area is bigger,higher deironing efficiency

Diversified running modes,both manual operation and PLC full automatic running is acceptable;in automatic mode,it can be controlled by plane multitanderm valve or several automatic valves
