Water cycles for wet treatment recycling processes Water treatment in the recycling industry

In the recycling of various materials, such as electronic waste, agricultural films, packaging, screens, etc. those materials are cleaned. This ensures a constant process stability and prevents a quality reduction of the valuable substances through contaminants. Dirt particles enter the washing water during the cleaning process. The water has to be purified in order to reuse it. Depending on the material to be processed, different kinds of dirt particles enter the water.

When DSD-packaging is processed, mainly food residues occur, whereas during electrical waste processing mainly (house) dust occurs. Whereas agricultural film is soiled with plant remains and soil. In the recycling process of screens, coatings of heavy metal play an important role.

As varied as the types of soils are, as varied the water treatment technologies have to be.

Pilot plants of Leiblein

Our products are available to rent for pilot tests. Due to our extensive rental park, we can put together complete test systems individually for your task.
