Description
 
In various cases the wastewater quality may be sufficient for direct discharge into the receiving water, but visible solids cloud the water.
A fine filtration with the backwash filters type M1XX and type FW or the screening drum type RS in the pumping station can remove all visible solids and up to 50% of all settleable solids.
 
 

Benefits

  • Improvement of the discharge values: reduction of the AFS content (thus of the CSB and BSB values) in the discharge to the receiving water
  • Supply of process water from the sewage plant effluent
  • Reduction of drinking water consumption
  • Reduction of solids before hygienization
 
 

Application situation

Mechanical treatment:
The RotoSieve drum is recommended as a further treatment stage in the inlet structure. The biggest advantage is the safe separation of the Q-tips (ears/wadding sticks). These can pass the rakes and are then found in all parts of the treatment plant. A screw conveyor with pressing and cutting device takes care of the disposal of the discarded material from the drum into a container.
 
Use of secondary clarification:
The water from the final clarification is often used as process water for spraying or splashing the rakes or screws. For this purpose it is sufficient to filter the water to approx. 100 - 300 µm to protect nozzles, fittings and valves. A further hygienic treatment of the process water does not make sense, because the spray water carries away fecal contamination which is deposited during cleaning.

 

Advantages of the GEFA filter:

  • Fully automatic function
  • compact and space-saving design
  • easy installation
  • Filtration range 10 - 3000 µm by simple exchange of the sieve elements
  • efficient filtration with fabric screens
  • patented suction-pressure cleaning system
  • Avoidance of residual dirt and back-side blocking of the screen fabric through patented vortex effect nozzles
  • low pressure difference across the sieve, thus no pressing of filter cake
  • very low rinsing quantity
  • large filter surfaces
  • low investment costs
  • fully automatic regeneration, even after flooding
  • low pump load
