Information About Filter Cloths
When separating solids from liquids using a filter press, the very foundation lies within the filter cloth. This is the front line of the dewatering process. The cloth will separate the fine particles from the water or other type of liquid in your application, forming a filter cake. This is the deposit of solid materials left behind after the filtering process.
We offer stock cloths in various sizes for quick shipping. We can also customize cloths to match the specifications of your filter press, providing for a perfect fit.
Our fabric department maintains a high volume of rolled goods with a wide variety of filtration characteristics that cover virtually any filter press application.
Filter Cloth Specification
We place the emphasis on value, which is why we offer products that keep costs down. Our products are of the highest quality, and we offer filter cloths made of the following materials:
Our sales team will offer recommendations of which product to use for your specific needs, taking into account the required filtrate clarity, flow rate, and cake release of your project.
We also offer options for latex edging and hook and loop material, which can help decrease installation time and improve sealing on non-gasketed cloths.
Importance of Cleaning and Replacing Filter Cloths
When using a filter press for separating liquid from solids, you need filter cloths that are in top-notch condition. When the porosity of the material becomes compromised, it may not perform the separation process effectively.
During normal operation of the filter press, the filter cloths may begin to accumulate microscopic particles over time, and eventually become plugged, or “blinded.” This in turn causes a lower rate of filtration and a wet filter cake, which dramatically reduces the efficiency of the filter press.
If you are experiencing a wet filter cake or longer than normal filtration cycles, it may indicate your filter cloths have become blinded, and washing the cloths may be in order.
Filter Press Cloth Cleaning
Filter cloths can be cleaned without having to remove them from the filter plates or remove the plates from the press. Read our blog post, “Options for Cleaning Your Filter Cloths“ to learn more.
When to Replace Filter Press Cloths
When the fabric weave becomes stretched with use, it may become too porous and unable to perform efficiently. Conversely, filter cloths may become clogged when particles become lodged deep into the fabric. In this case, it’s ineffective to clean the cloths with a cold-water pressure sprayer or chemically. When your filter press no longer forms a solid cake, it is time to replace the filter cloths.
