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.
