Secondary Squeezing Membrane Filter Press with Lower Cake Moisture
membrane filter press consists of membrane plate and filter chamber made of ordered filter plates. The slurry materials are sent to filter chamber by the pressure of feeding pump and then go into filtrating media(filter cloth) to separate solid and liquid in slurry material.When solid in slurry material becomes cake shape, air is sent to membrane to fully squeeze the solid to reduce moisture content. If users have high requirement about filtration of sticky material and moisture content ratio, this machine has its own special characteristics to meet the need.
Features and application
The main difference between ordinary chamber filter press and membrane filter press is in addition to the feeding pressure filtration , the special structure of the membrane plate make it has a secondary filtering function, namely the pressing filter. During operation, when the end of feeding, can inject high-pressure fluid medium(air or water)int othe membrane plate, in which case it will summon the entire diaphragm, oppression cake, so as to achieve further dewatered cake.
Membrane filter press has been widely used in various areas that require solid-liquid separation. It is considered an alternative to upgrading equipment of ordinary chamber filter press.
Membrane filter press with fearures of high compress pressure, good corrosion resistance, easy maintenance, safe and reliable, is the first choice of metallurgy, coal, paper, coking, pharmaceutical, food, brewing, chemical and other industries.
Membrane filter press applied to sludge, sewage treatment, the cake moisture has done below 30%, compared to the traditional chamber filter press ,the solid content of the filter cake can highest increased more than 2 times.Thus cake transportation costs greatly reduced, the cake can transported into power plant for burning directly.
The real change of sludge to resources, sewage becomes springs.
Membrane filter press in processing capacity per unit area, reduce cake moisture, adaptability to the nature of the materials deal with aspects have shown good results.
membrane squeeze filter press consists of membrane plate and filter chamber made of ordered filter plates. The slurry materials are sent to filter chamber by the pressure of feeding pump and then go into filtrating media(filter cloth) to separate solid and liquid in slurry material.When solid in slurry material becomes cake shape, air is sent to membrane to fully squeeze the solid to reduce moisture content. If users have high requirement about filtration of sticky material and moisture content ratio, this machine has its own special characteristics to meet the need.
Membrane plates are constructed in the same basic method as the recessed chamber plates. The drainage surface of the plates, however, are flexible. After filtration, when the chambers are filled with solids and while the filter press is stilled, air pressure is exerted behind the flexible drainage of the plate. The membrane in turn inflates to exert pressure on the filter cake which have been formed. The cakes are then squeezed to reduce the amount of remaining moisture prior to cake discharge
Membrane filter press plates are made from TPE material moulded. Diaphragm and TPE are enchased togerher to become firm, do not fall off easily and have a long service life.
Main Features
1) High dewateing level,low cake moisture content
2) Well quality filter plates
3) Second queezing process
4) Long service life ,high-level automatic,easy use
