Multi-Roll Filter Belt Presses

The Parnaby multi-roll filter belt press is used at the last stage of effluent treatment.  It is an efficient and reliable method of separating solids from liquid to produce dry filter cake and particle-free filtrate.

Benefits

•  High throughput
•  Continuous operation
•  Dewatered, easy-to-handle filter cake
•  Excellent quality of filtrate
•  Minimal operator supervision
•  Maximum reliability
•  Minimum maintenance
•  Low capital cost

Specifications

•  Fully galvanised frame
•  Long life, double-row spherical bearings
•  Heavy duty rollers with 1mm irathane coating
•  Variable pneumatic belt tensioning
•  Variable speed main drive
•  Stainless steel filtrate trays
•  Long life polyester filter belts
•  Stainless steel belt washing sprays

Operation

The sludge is treated with a polymer flocculant and then squeezed between two filter belts to remove the liquid.  The arrangement of the rollers ensures that pressure is increased as the sludge gets drier.  The liquid squeezed through the filter belts drains into trays under the main rollers (6). In a closed circuit system it is then pumped back to the thickener/clarifier cone.
