AMSTON® Filter Press for sludge dewatering and slurry dewatering Sludge and slurry can be dewatered or dehyrated in an Amston Fiter Press; a pressure filter press designed to dewater sludge and slurry that has been produced from solid liquid separation processes. A solid dry cake is formed after the end of the filtration cycle. The Amston Filter Press can achieve a 90% reduction in sludge volume. In most instances, the sludge or slurry requires chemical conditioning in a batch-mixing tank upstream of the unit (typically cationic and aniomic polymers).The AMSTON Filter Press consists of a series of parallel plates, each fitted with a filter cloth. The filter plates are manufactured from single mould ultra high molecular, heat stabilized polypropylene. In most applications, the cloths are also manufactured from polypropylene. The main frame of the Amston Filter Press is fabricated from high tensile mild steel with a heavy-duty paint specification, to ensure proper resistance to corrosion as well as long life. Once the plate pack is closed via a hydraulic system, feed slurry is pumped into the filter press. The slurry enters between the filter plates and water is forced through the cloths and collected in a filtrate trough, leaving behind the solids to form a compacted cake. Cake discharge will be either manual, semi automatic or automatic. To view an illustrated diagram of how an Amston Filter Press works Click Here. The Amston Filter Press range is available in manual, semi automatic and fully automatic versions. Options include assisted plate shifting, automatic plate shifting, cake washing, plate vibration mechanisms, core blowing and membrane squeeze and mixed membrane filtration.
