CLEANTECHINDUSTRIAL

Exhaust air must be cleansed from odours, solvents, dust, gas-es and other substances. There are a wide variety of filter sys-tems and methods available for removing or neutralising these substances. Besides compliance with the regulations, we always consider the economic efficiency of the procedures.

We assess the technical aspects and the operational safety of the methods and integrate them into your process with a focus on economic optimisation. E

Wastewater and exhaust air from industrial processes is always process-specific. We help you find the optimal technical and commercial solution for the treatment of these material flows.

CUSTOMIZED SOLUTIONS

The composition of industrial wastewater varies widely. For example, food processing, the paper industry, metal refining, cosmetics industry, etc., all pose different specific challenges. So in each case a customised process must be developed to handle the specific pollutants in-volved. It all begins with a careful analysis so that the right method can be chosen. Sometimes it is enough to install a preliminary treatment stage – then the mu-nicipal WWTP can handle all the remaining pollutants.

Besides technical support, we also calculate the most economi-cally attractive option for you.

TWhen there are special require-ments, we test the procedures in a laboratory. That allows us to get to know the advantages and disadvantages of the dif-ferent processes. In a second step, the best process is tested in a pilot plant. Based on these results we can design the waste water purification plant. Thanks to close cooperation with the Envilab laboratory, we guarantee the right measuring technique and the professional interpretation of the results. Our approach also allows us to adapt existing processes to the customer’s needs.
