Filter elements used in the chemicals industry must be able to meet a range of chemical resistance levels as well as extreme filtration parameters. A multifunctional membrane plate is therefore required. Extensive know-how acquired through detailed research and development and years of proven experience are evident in EnviroTech and Klinkau’s range of membrane plates. The filtration of chemicals at temperatures ranging from -10°C to 95°C requires carefully selected materials to ensure stability and resistance. Wash processes within the chemicals industry are often complex so the plate design is decisive in achieving the necessary levels of washing efficiency. EnviroTech and Klinkau’s welded membrane filter plates in their standard and empty chamber versions are ideal for such tasks and have been delivering excellent results for many years.
Specific examples of applications in the chemicals industry
After Tio2 washing, welded or replaceable membrane filter plates in their empty chamber versions are then used for the chemically non-aggressive final filtration, as well as for coating and gypsum filtration.
The washed titanium dioxide undergoes dewatering at this stage of the process. To save energy in the downstream drum drier, efficient dewatering is required. The membrane plates are therefore capable of squeeze pressures of 30 bar and achieve far drier filter cake results than the standard squeeze pressures of 12 to 15 bar.
