Variable volume filters and presses

A family of filters devised to handle suspensions of finer solids which are difficult to pump and/or filter. Typical feeds include suspensions of gelatinous and fibrous materials and those particulates containing occluded liquid within an inherent porous structure. 

Typical uses Batch processing of suspensions forming compressible filter cakes where dry cakes and/or efficient post-treatment are required. 

Typical particle size and feed concentration range 1-200 pm and 0.3-30+% w/w. 

Typical uses Semi-continuous processing of solids forming compressible filter cakes that require efficient post-treatment.
