Thanks to an evaporator, you can work without discharge. After all, you purify the waste water so that it can be reused. 

With a vacuum evaporator, the waste water will first be evaporated and then condensed again. The pollution in the waste water does not evaporate. That's how almost pure water can be obtained, which can then be reused in production.
In addition to the purified water, there is also a concentrate flow.  It contains all the pollution.  This current can no longer be further processed, but must be transported to external processing.  In most cases this is 5 to 10% of the treated waste water.

If you choose an evaporator, a zero discharge is possible.

PCA can help you with this technology, both in design and construction of the installation. In addition, we also handle the monitoring and maintenance of the installation.
