When Should You Change Filter Press Cloth?

Introduction To The Life Of Filter Press Cloth

Filter press cloth plays a key role in optimizing the filter press operation. The success of your filter press system in delivering absolute results depends on one element i.e., the condition of your filter cloth.

A filter cloth that is worn out, damaged, or too old will prevent your system from achieving the filter clarity and slurry that the procedure demands. Keeping your press filter regularly updated with the replacement of press cloth will ensure that the processes run as efficiently as possible.

The life of filter cloth is shortened by mechanical abrasion, chemical degradation, or even both. The shortening of cloth life is also affected when the material being filtered is clogged or blinds the filter cloth. Such things can impact porosity and will no longer allow the filtrate to flow properly.

Filter Press Cloth: How Often Should You Replace Them?

If you regularly filter harsh chemicals in filter press types, the cloth will reduce its effectiveness over time. It is eventually necessary to replace your press cloths in such cases. However, filter cloths can't tell you exactly when to replace them.

So how exactly will you estimate when changing your filter press cloth? Since there is no expiry date on your cloth, sure noticeable signs will help you determine when your press needs a cloth replacement.

We will help you cover some signs that your filter cloth may need to be changed to understand processes better.

1. Your filtration process times get delayed.

   Nobody must be aware of your filtration process better than you. You should have a better idea of roughly how long your press filter takes to complete one filtration cycle. If you notice a delayed procedure, it depicts that your cloth’s performance is on the downslope.

   Keeping track of how long your process takes is crucial, so you know when performance is suffering.

2. You observe tears or holes in your filter cloth

   As your filter cloth ages, it will become worn and torn due to the friction created by your machine and the products you work with. Although tears and holes are natural, they may happen even faster if you work in an industry like mining or stone cutting because they deal with abrasive ingredients.

   Moreover, if you are not working with offensive materials, damage is still inevitable, so it is preferable to inspect your cloth during the cleaning process regularly.

3. Your filtrate clarity has a higher opaque level

   For industries such as chemicals, food & beverages, water, and much more, filtrate clarity is essential for delivering the result end product demand. Maintaining filtrate clarity is necessary for most filtration applications, and it should be an essential factor to keep an eye out for.

   Changing out your cloth promptly is the best course of action if your yields are beginning to show signs of degrading purity.

4. The moisture content of your filter cake solids is higher

   It is always the goal of filtration processes to ensure that the cake solids are as good as possible. Producing proper solid cakes is a sign of a complete separation between liquid and solid.

   Wet solids residue remains, or the sloppy texture of cakes immediately indicates that your cloth is losing effectiveness. In such cases, the filter cloth is not properly extracting liquids resulting in filter cloth blinding.

   It is possible to control blinding by regularly cleaning your cloth, but you may need to replace them if you continue to have wet cake solids or low-quality cake solids.
