Plate and frame filter press
Plate and frame filter press is the first machinery used in chemical dehydration. Although plate-and-frame filter presses are generally intermittent operation, large investment in infrastructure equipment and low filtration capacity, they are still widely used in some small wastewater treatment plants because of their advantages such as high filtration impetus, high solid content of cake, clear filtrate, high solid recovery rate and low consumption of conditioning drugs.


General description
After the sludge is concentrated and digested, the water content of sludge is still about 95%~97%, and the volume of sludge is still very large. Sludge dewatering can further remove void water and capillary water in sludge andits volume is reduced . After dewatering treatment, the water content of sludge can be reduced to 70%~80%, and its volume is 1/10~1/4 of the original volume, which is conducive to subsequent transportation and treatment.
Mechanical dewatering of sludge includes filtration dewatering, centrifugal dewatering and press dewatering, and filtration dewatering includes vacuum filtration and pressure filtration. Centrifugal dewatering is carried out by centrifuge, and press dewatering is carried out by screw press or rolling press. Pressure dewatering  and centrifugal dehydration are commonly used.
Sludge filtration and dewatering is driven by the pressure difference between the two sides of the filter medium, which forces sludge water to form filtrate through the filter medium, while solid particles are intercepted on the medium to form filter cake, so as to achieve the purpose of sludge dewatering. Plate and frame filter press is the first machinery used in chemical dehydration.
Although plate-and-frame filter presses are generally intermittent operation, large investment in infrastructure equipment and low filtration capacity, they are still widely used in some small wastewater treatment plants because of their advantages such as high filtration impetus, high solid content of cake, clear filtrate, high solid recovery rate and small consumption of conditioning drugs.


Product characteristics:
Plate and frame filter press is a kind of equipment for separating solid and liquid in industrial production. It is used in chemical industry, ceramics, petroleum, medicine, food, smelting and other industries. It is also suitable for industrial filtered sewage treatment, and the hydraulic type is integrated with mechanical, electrical and hydraulic. The hydraulic equipment is used for pressing and the manual machinery is used for locking and holding pressure. The operation and maintenance is easy , safe and reliable.

The working principle of plate and frame filter press: used for separating solid and liquid. The mud cake filtered by filter press has higher solid content and better separation effect. The basic principle of solid-liquid separation is that the mixed liquid flow passes through the filter medium (filter cloth), the solid stays on the filter cloth, and gradually accumulates on the filter cloth to form the filter cake. The filtrate part permeates the filter cloth and becomes a clear liquid without solid.


Product uses:
Coal washing, inorganic salt, mining, alcohol, petroleum, chemical industry, fuel, metallurgy, medicine, food, textile, printing and dyeing, paper making, municipal sewage treatment and other fields.


Product advantages:

The material of the filter plate is alkali-free glass fiber polypropylene, which make the filter plate  has elasticity of rubber filter plate and also has the toughness and rigidity of reinforced polypropylene filter plate. The thickness error is 0.02 which is processed by special processing center. The flatness is 0.015.
