Filter module systems can be used for waste water treatment, manufacturing of mineral pigments, recovery of fibers, dewatering of ceramic bulk, filtration of metallic salt solutions, coal and ore from flotation processes, separation of oil and so on. The effectiveness of a filter apparatus depends on the construction and the material of the filter medium support tray. Some common materials are wood, aluminium, cast iron, ductile iron, stainless steel and material compounds out of steel and rubber. These elements are showing a lot of disadvantages such as low chemical and corrosion resistance, high weight, unfavourable drainage, considerable abrasion, limited working life, fluid absorbency and bad sealing. Polypropylene turned out to be the best material due to its most favourable price-power-performance and interesting combination of excellent properties. Herein, two models of filter module were employed for benchmarking. To suggest economic substitute material for them, different amounts of the chopped glassfiber and CaCO3 were incorporated in PP for filter recess and filter base. PP/EPDM blend was employed as filter membrane as well. Their parts were also thoroughly investigated in terms of tensile properties, flexural properties, durability against dynamic mechanical movement, thermal stability and so on.
