Product advantages:
1. High efficiency: 24 hours continuous operation, no need to stop backwashing.
2, low operating costs: no need for high lift and large flow backwash pump.
3. Low maintenance cost: It has no rotating parts except quartz sand filter material during operation, low failure rate and low maintenance cost.

Product principle

Used as the primary filtration of groundwater and deep well water to remove large particles.Sand removal rate is up to 99%.

Features

• Simple structure, low cost.
• Easy to install and operate. Maintenance-free
• Small and large volume processing capabilities, saving installation space

Design and selection of models
1. Water quality classification

A.: Water of good quality: city tap water, well water from stable aquifer.

B.: Water of general quality: cooled circulating water, surface water treated by sedimentation, and drained water treated by effective deposition and completely biological treatment.

C.: Water of relatively poor quality: groundwater from aquifer of poor quality, drained water treated by effective deposition but with poor biological treatment, and surface water with enormous microbes.

D. The worst quality: well water with rich iron and manganese elements, surface water affected by flooding and without sedimentation, and drained water without precipitation and biological treatment.

Different water qualities have different influences on the filter's operation period, so in general it is better to keep the system's backwash intervals no less than 1 hour.
