Microplastics, which are any fragment of plastic that is less than 5 mm in size, can be found in nearly any kind of water source on the planet, including rivers, lakes, bays, and even sea ice. One of the biggest obstacles to removing microplastics from wastewater is the ability to measure how much is actually in the water. Unwanted chemicals or bacteria can be detected and measured using different analytical processes. Unfortunately, no such process exists for microplastics.
Physical media such as disk filters are an effective and affordable solution to microplastics. A disk filter can be installed at the end of a wastewater or industrial effluent treatment system to remove the physical plastic particles that may have slipped through a clarifier or other treatment processes.
But not all disk filters are equally as effective. Pile cloth media (PCM) has one of the highest estimated microplastics removal rates. PCM filters have numerous advantages over traditional screen filters that make them an ideal solution to a difficult problem.
