SLUDGE DEWATERING BY USE OF FILTER BAGS
MODEL: FILSA
Function:
• Sludge removal and dewatering coming from small and medium sized treatment
plants.
• Once the bags have separated the major part of the sludge from water, they
settle in the drying area for the final
dewatering phase.
Characteristics:
• Bags made with a porous matter to
allow the water and drying air
passage, and prevent in the same
time from the clogging of the
retained solids.
• Made of AISI 304 stainless steel.
• Filter bags made via drying and
fixing process.
• Motorized valve with security lock
and subsidiary valve.
• Level probe connected to an
instrumentation board.
• The filtration process is automatic
and its filling is made by gravity.
• Low maintenance and power costs.
• High efficiency, allows to obtain dry matter between 10 and 20% after a few
hours, and dry matter between 40 and 80% after outdoor storage.
