Why Filter Plates Broken


1. The filter press is damaged, causing uneven force on the filter plate, and the filter press its pressure crushes the filter plate;

2. It is caused by the slurry .

The slurry contains hard particles which will cause the membrane filter plate easily damaged.

3. The feed hole is blocked. Several filter plates near the feed inlet are damaged, which can be preliminary judged to be blocked at the feed inlet. If the slurry concentration is too large, or the cleaning is not timely, the feed hole will be blocked.

4. The feed pressure is too high.

When back pressure occurs, or the pressure gauge display exceeds the pressure specified on the nameplate, Indicates that the feed pressure is high. The solution is adjusting the pressure controller system.

5. The material concentration is high and the fluidity is too poor, the solution is reducing the material concentration and improve slurry mobility.

6. The feed temperature is too high.

Understand the temperature of the slurry firstly, when the temperature of the filtered slurry exceeds the filter plate equipped. When using the temperature, you should explain the reason to the customer, and replace the appropriate filter plate or take the temperature of cooling slurry before filtering;

7. The filter cloth is damaged and the outlet hole is blocked.

There are a few individual water holes and the filtrate is turbid, it can be judged that the filter cloth is damaged and the water holes. If there is no liquid, it can be judged that the liquid hole is blocked. The filter cloth should be replaced and the liquid outlet hole should be cleaned.
