Vertical(Tower) press filter is an essential equipment for solid-liquid separation in the filtration process. Some users may encounter the problem of high moisture content in the filter cake. The following reasons may be the cause of this problem.
Caused by filter cloth factors
1. Clogged filter cloth
Filter cloth may have the blockage issue during use, due to the accumulation of material particles, causing the aperture to become blocked. This can seriously restrict the passage of water, resulting in a high moisture content in the filter cake.
2. Poor quality filter cloth
Filter cloth of inferior quality has a rough surface that can cause the cake to stick to the cloth's surface, leading to a higher liquid content in the cake. Additionally, poor quality filter cloth is susceptible to deformation, which can compromise the filtration process.
3. Unsuitable filter cloth
If the filter cloth is not chosen according to the filtration equipment, working environment and other factors, it will also lead to poor filtration effect and high moisture content of filter cake.
Caused by equipment factors
1. Insufficient pressure
The vertical filter press's filtration power derives from the pressure exerted by the equipment. If the pressure is in, the filtration power will be reduced and the efficiency of cake dewatering will decrease.
2. Improper maintenance of equipment
Maintaining vertical filter presses is essential for ensuring optimal performance and maintaining the moisture content of the filter cake during use.
Caused by filter material factors
1. High material viscosity
If the material is sticky, it is easy to adhere to the surface of the filter cloth and not easy to remove. This increases the difficulty of filtration and can cause blockages in the filter cloth and discharge channel.
2. Uneven material particles size
This will easily lead to clogging of filter cloth and uneven filter cake.
In summary, when dealing with vertical filter press cake pressure, it is essential to consider and address the problem from three perspectives: filter cloth, equipment and materials. For further information, please refer to the official website of BOLIAN or contact us for consultation.
