How To Tell If The Sludge in The Filter Residue Has Been Pressed Dry

After the production process, one of the achievements is to see whether the sludge meets the requirements you have set for yourself. For the sludge in sewage treatment, how to judge whether the sludge in the filter press is pressed dry, we can judge from three aspects:

 

The feed pressure rises to the set pressure; the discharge of liquid from the hole of the filter plate is obviously reduced; the material in the storage tank is obviously reduced. These are the basic three judgement criteria.

 

However, the storage tank material is obviously reduced, and can not determine whether the filter residue is completely dry, can only be understood as the completion of the feeding process.

 

The completion of the feeding process can be judged from two points: the feed pressure has reached the set feed pressure; filter plate discharge is significantly reduced.

 

If you want to further reduce the moisture content of the cake. You can take another way: improve the filter press feed pressure, however, must ensure that the hydraulic cylinder pressure is sufficient; compressed air, blowing to take away the moisture.

 

This time you can look at the water outlet, in the pressure to reach the set value, if the water is a drop by drop, and the drop is very slow, basically almost. According to the nature of the material depending on the situation.
