In many parts of the world, the metal-processing industry has eversince been of special importance. As a known fact, various types of waste water result from metal-related production processes. Every year, more than 5 million tons of cooling lubricants mixed with water have to be disposed of.
Here we are able to offer membrane processes which differ from traditional filtration treatments in a way that the phase to be separated does not accumulate on the surface (forming the well-known filter cake). The concentration of oils rather takes place in the liquid phase itself. Emulsified oils and residual solids are trapped in a closed loop until they reach a set concentration level. Thus, via our T-CUT and T-CUT PP modules, a traditionally discontinuous filtration process turns into a continuous one which runs automatically and without monitoring effort.
