Filter module systems can be used for waste water treatment, recovery of fibers, filtration of metallic salt solutions and so on. Suport tray materials are wood, metal and rubber. These elements are showing a lot of disadventages as for example corrosion resistance and bad sealing. However Polypropylene turned out to be the best material due to price-power-performance.Thermoplastic polyurethane(TPU) was employed as filter membrane. Their parts were also thoroughly investigated in terms of tensile properties, flexural perperties, durability against dynamic mechanical movement, thermal stability and so on. |
