Filter operations
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
–
Backwash
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.

Processed water circulation
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:
