In filter operations, the water flows via
– Immersion pump
– multi-channel valve in position FIL-
TERN/FILTER...
– Gravel filter (flow direction of filtering)
– Shutoff valve recycled water
– to the recycled water tank
During backwash, the water flows via
– Immersion pump
– multi-channel valve in position RÜCK-
SPÜLEN/BACKWASH...
– Gravel filter (against flow direction of fil-
tering)
– Restrictor
– To the sludge collector
In order to prevent sand from being forced
out, the volume flow is restricted by a throt-
tle during the backflow phase.
Caution
Risk of damage. An increased backflow
speed rinses the filling inside the filter. The
backflow speed was set up by a specialist
during the machine startup and must not be
modified.
During final rinse the water flows via
– Immersion pump
– multi-channel valve in position
NACHSLPÜLEN/RINSE...
– Gravel filter (flow direction of filtering)
– To the sludge collector
Purpose of circulation:
– Additional movement of the recycled
water, especially when the washing
system has come to a standstill, to
avoid formation of brackish water and
reducing the odour problem.
– Additional supply of air to the water to
avoid odour problem
The water flows from the recycled water
tank to the sludge removal as follows:
– Recycled water tank
– Circulation valve
– Circulation pump
– Sludge removal
