Automatic back flush industrial sand filter

 Multimedia filter is usually called depth filters, water flows through a certain thickness, media layer with a certain particles size, then reached the filtering effect .The media may be quartz sand ,gravel or granular materials. filtration level depends on the particles diameter and flow speed through filter bed. INOCO provides a series of various forms of such product sand accessories,can also provide control system for using single or multiple parallel situation, INOCO is willing to offer you the products design ,perfect system and help you select filter media such as sand ,quartz sand ,activated carbon and multilayer media.

 1.    higher filtration flow speed. the fastest can reach 35m/h, larger drain capacity and longer work period, suit for large water capacity industrial water and low suspended solid content. 

2.Generally the turbidity is below 1 mg/L for after-treated water. At the same time, partly eliminate the organic matter, bacteria and chroma. Meet bruises requirements in water of suspended solid content.

3.  Use sand for filter media, simple device structure, easily operate and maintenance. 

4. After the filter layer failure, you can use the method of backwash water(water wash filter layer from the bottom to up, please see below pc),then restore the filtration ability.

5.Sand material widely distributed, easily produce and low cost.

6. We are manufacturer equipped with a strong team and profession engineers who have rich experience. also supply best filtration solution for you.

7. We always change and wish the best service for you, we have 25000 customers all over the world. such as Thailand, Korea, Vietnam, USA and so on. 

 Water flows into the filter inlet then through filter layer,suspended impurity in water will be adsorpted by filtering layer,filtered water from filtering cap flows to outlet,cleaning can be done by backwashing ,the flow is the reverse flow from water filtering cap upward,causing filter layer turbulent ,meanwhile the adsorbed impurity are released and discharged from drain valve,backwashing process is completed automatically by pressure differential or timing.
