First Claim
Patent Images
1. A method for dewatering sludge, the method comprising:
- introducing a pre-measured quantity of one or more polymers into the sludge to agglomerate entrained solids;
routing the agglomerated sludge to an integral primary filtration station, the primary filtration station comprising one or more primary filtration chambers, each of the primary filtration chambers further defining a cylindrical cavity for receiving at least one industry standard filter bag; and
dewatering the agglomerated sludge within the filter bag.

Abstract
Methods, apparatus and systems for dewatering and drying the dewatered sludge. Sludge pumped into the sludge dewatering apparatus is mixed in-line with a pre-measured quantity of polymers to agglomerate solids entrained in the sludge. The agglomerated sludge is routed to a filtration station comprising filtration chambers. The filtration chambers are fitted with industry standard filter bag. The agglomerated sludge is subjected to dewatering in the filter bags and the dewatered sludge is subsequently compacted, dried and discarded.
