Features

Highly polluted waste water, contains metals.

SITUATION

A large waste disposal company in the region, which manages a waste acceptance site, has received stricter environmental protection regulations from the local authorities. Because of this, it is necessary to build an industrial wastewater treatment system.

PROBLEM

A highly polluted and variable wastewater stream needed to be treated. The wastewater comes from many sources such as oil waste from tank cleaning. A biological treatment is difficult to implement, because too many metals are present in the wastewater. Therefore, the removal of carbon and nitrogen concentrations must be done by another method. At the same time the oil should also be removed.

SOLUTION

We have designed a plant for our customer that is both compact and capable of handling all process steps.

A compact screening screw discharges the waste water into a buffer container. All ClearFox® Industrial wastewater treatment systems are installed using the same compact design.

The subsequent dissolved air flotation is able to remove all the oil and a very large part of the COD and BOD5 concentration without biological treatment.

The ozonation that now takes place, in which ozone is produced from oxygen with the aid of an ozone generator and this is introduced into the wastewater flow, ensures partial outgassing of the nitrogen from the wastewater. Here, too, all technical equipment is installed in a container to save space. Only the pre- and post-buffer had to be placed in an adjacent container for the purpose of partial flow treatment.

Afterwards the waste water is led over an activated carbon filter, where all residual ozone, as well as other fission products of the ozonation and other substances react highly efficiently. The ion exchanger, as the last unit of this treatment plant, ensures the remaining reaction of the nitrogen and is at the same time a highly effective police filter, which provides additional safety with regard to the pollutant values.

This compact plant consists of six containers.
