Membrane filtration
The filter element is made of metal wire, filter cloth, filter paper, yarn, microcellular plastic, microcellular ceramic and other materials. It is fixed on the tube plate and put into the pressure bucket. The filtering area is 3-30m2 and the working pressure is 0.2MPa. Fine filtration or ultra fine filtration with filtration accuracy > 0.1 μ m, for small batch production.
Tubular filter
The micron level filtration equipment, which is composed of rigid porous filtration medium, can filter the slime material of 0.5 μ M-100 μ m at one time, and can obtain the filtration effect of filtrate clarification.
- It has high filtering precision and wide range, which can meet the requirements of different filtering precision.
- Resistant to acid, alkali, salt and various organic solvents, non-toxic, tasteless, no foreign matter falling off
- Vertical structure, small floor area
- Simple operation, large processing capacity and low investment cost
- Using compressed air or “air water” to recoil and discharge slag for regeneration, or chemical regeneration, with long service life of filter element.
Continuous pressure filter
The operation process of feeding, filtering, washing, blowing and unloading shall be continuous at the same time. High filtering speed, low moisture content, clean environment, and more suitable for automatic control features.
Drum pressure filter
Continuous operation, low moisture content of filter cake, good washing effect and low washing water consumption. At present, the maximum filtering area is 8m2 and the operating pressure is about 0.3MPa. The disadvantages are complex structure, difficult maintenance and suitable for large-scale production.
