The Key factor that allows this method is that the flocks of bacteria are globular with 2-3 mm diameter. These flocs can be easily trapped with a laminated poly bag. These bags are used to transport sugar, fertilizer and other food stuff, and at the end of the cycle, they are discarded. These used bags are available in secondary market at very cheap rateSludge Dewatring System

The equipment is very simple , as shown on facing page: A rustproof stainless steel table is manufactured with provision to hang 2-4 bags, and just like tea – strainer, the water drains out. However, Because the sludge is not squeezed, the bag remains wet. So, after the water stops dripping, the operator has to close the bag and place it on the airing racks to let it dry for several days.

Operation and maintenance considerations:

Typically, in small plants, the filter press may be sized for a single batch operation per day. In large plants, three batches per day, one per shift, is the norm.

Fresh sludge (not more than a day old), kept fully aerated and mixed (agitated), dewaters easily in the filter press. Hence, sludge must not be stored in the holding tank for longer durations.

The desired quantity of polymer needs to be added 15 – 30 minutes before the dewatering

operation. Filter press operation is carried out over 3 – 4 hours, or when filtration ceases.

After every dewatering operation, the filter cloths must be thoroughly cleaned, so that clogging in the pores of the woven polypropylene filter fabric is avoided. Periodic cleaning of filter cloth with Hypo solution will also prolong the life of cloth. When the filtration process becomes excessively slow, it is time to replace the filter cloth with a fresh set.

Normal maintenance as prescribed by the manufacturer may be practiced for the high

pressure helical screw pump. Care must be taken not to damage the rubber stator of the screw

pump by dry running of the pump. It is generally preferable to locate the pumps such that positive suction is enabled.


  • Easy and cost effective installation.
  • Easy to apply to an already existing wastewater treatment plant.
  • Easy disposal of sludge due to the bag-fill system.
  • Small investment and waste disposal costs
  • Energy free drainage
