The best filter press cloth depends on your process or application. That’s why our years of filtration experience – with Micronics’ well-known industry experts – allow us to make the right cloth recommendations for you. Cloth selection is as much an art as it is a science!
Micronics supplies filter cloths to you based on detailed process criteria that you and your team provide to us. Often, our recommendations will be based on filtration testing. Should your process change, we do recommend that your filter cloth type is evaluated specifically for your new process & operating conditions. Time and time again, customers will find that a process change necessitates a change in cloth to ensure that the filter press operation is fully optimized.
For instance, did you know that a change in polymer or other chemical or physical treatments may alter the performance of your filter press?
Filter cloths come in many different materials including polypropylene, polyester, cotton, and various synthetic materials. The cloths are made from monofilament fibers, multifilament fibers, or spun fibers. Learn more about filter cloth terminology in our recent blog post.
Did you know that the smooth surface characteristic of monofilament fibers can help to improve cake release properties? The uniform circumference of monofilaments also enables fabrics to be produced with consistent pore sizes.
Multifilament and spun fibers are produced are produced by twisting several smaller diameter monofilament fibers together into a single strand. They are used to produce filter cloth fabrics that require a very tight weave and fabrics where high flow rates are not critical.
Pore size is an important consideration when selecting the proper filter cloth for a particular application. Pore size is determined by the number of fibers, fiber size, and the type of weave. These influence flow rates, particle retention, and the tensile strength of the fabric.
Filter cloth is the key foundational ingredient for any filter press operation. Filter cloth is the initial barrier that separates the solids from the liquid. The filter press cloth must remain porous in order to provide high filtration rates!
