Backwash Automatic Sand Filter For Water Treatment Pre Filtration
Disc Filter Introduction
The Disc filter has a highly efficient backwash, automatic continuous production. Low water consumption and a compact design, the system alters its backwash cycle automatically between units to ensure constant output and minimal pressure loss.
Automatic disc filter system with disc filtering element with 2"/3"/4" backwash valve,manifolds,controller. Easy to install.Automation available in 220V.
Disc Filter Features:
Precise filtration: Filter discs with different precision can be selected according to water requirements. There are various specifications such as 20 micron, 55 micron, 100 micron, 130 micron, 200 micron, and 400 micron, and the filtration ratio is greater than 95%.

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.
