Recycling of salt out of process waters

Many process waters contain salts which are impossible to be treated or separated in common purification plants (e.g. dump seepage water).

By a combination of both, proven crystallization plants with a connected calcination unit, a type of plant had been developed in which waste waters are desalted by thermal processes.

In plants we installed in the past pure and in particular saleable salts could be produced from dirtiest process waters.
