Pressure Sand Filter
 

a href="http://pressuresandfilter.com"pressure sand filter/a
consists of a pressure vessel-this could be either vertical or
horizontal-fitted with a set of frontal pipe work and valves, graded
silica quartz sand supported by layers of graded under bed consisting
of pebbles and gravels, a top distributor to distribute the incoming
water uniformly throughout the cross section of the filter, and an
under drain system to collect filtered water.

Raw water flows down wards through the filter bed and as the suspended
matter- which has usually been treated by addition of a coagulant like
alum- is retained on the sand surface and between the sand grains
immediately below the surface. There is steady rise in the loss of
head as the a href="http://pressuresandfilter.com"filter/aprocess
continues and the flow reduces once the pressure drop across the
filter is excessive.

The a href="http://pressuresandfilter.co.in"filter/a is now taken
out of service and cleaning of the filter is effected by flow
reversal. To assist in cleaning the bed, the backwash operation is
often preceded by air agitation through the under drain system. The
process of air scouring agitates the sand with a scrubbing action,
which loosens the intercepted particles. The filter is now ready to be
put back into service.
