The Sand filter cylinder is compacted and arranged with filter materials with different particle sizes from bottom to top. When the water flows through the filter layer from top to bottom, the suspended substances contained in the water flow into the tiny pores formed by the upper filter material, which are subject to adsorption and mechanical flow resistance, and the suspended substances are intercepted by the surface of the filter material. At the same time, these suspended solids are "overlapped" and "bridged", forming a film on the surface of the filter layer and continuing the filtration. It can effectively achieve the filtering effect.

This Monday received calling from our Macedonian customers , his power plant customer wanna reconfirm sand filter required spec .

Material : Carbon steel

Effluent turbidity: ≤ 5mg/l

Connection size : DN125

Working temperature: ≤90℃

Working pressure: PN16

Filter material layer height: 1000-1200mm

Back washing time: 4-6 minutes

Further, Our engineer provided detailed tech drawings and working video .

Customer feedback is very helpful to get this project , will give news on the weekend .
