Filtration technology - Import export

KIRSCH Kunststofftechnik specialises in (re)shaping transparent plastics with high optical quality. In our 4 different forming-furnaces we can process panels and components up to 3000 x 2000 mm of size. Special filtration technology, cleanness and experience contribute to form the transparent panels without dust inclusions. Our furnaces are equipped with modern controls to target individually required heating and cooling curves for each plastic. Thus, we can achieve not only an exact temperature during forming, but also control the cooling process accordingly to accomplish a nearly distortionless plastic. We can process plastics two-dimensional, as well as three-dimensional.

Coating colour recycling at paper and cardboard industries During the production of coated paper, it has to be cleaned with water and so, waste water results with pigments of the coating color. Because of their properties, exisiting precipitation plants are working hard on these types of waste waters. Alternatively to precipitation plants, membrane filtration technologies can be used to recover these high-value coating pigments. For that, the water with coating color pigments is circulated through the membrane plant until the required concentration is reached. The permeate is free of particles the CSB value is reduced significantly. It can know be handled by the precipitation plant, which is relief by the removing of the pigments. The concentrate with coating color pigments will be recirculated into the production process. Advantages: Reduction of coating color and pigments consumption Reduction of solid amounts in the waste water, which means reduction of operation costs
