Clean Air and Clean Water for Industries All Over the World

Overview

The responsible approach to the use of air and water, our vital resources, is one of the global challenges of our time. Since 1991, DAS Environmental Experts has met this challenge with targeted investments into future-oriented technologies for waste gas abatement and water treatment.

In this spirit, we place the highest expectations on our development and production, and on all of our partners at our branch locations. We share our company’s success with our employees and the world-at-large.

  • STYRAX
    The STYRAX tool family uses burn/wet technology and was specifically developed to manage demanding waste processes like CVD, Etch, EPI and LED processes. STYRAX is also available as a plasma scrubber for the electrical treatment of all types of waste gas....

  • Operation Principle of the STYRAX as a Burn-Wet Abatement

    Hazardous substances of process waste gases are treated directly from where they originate (Point-of-Use). In this optimised burn/wet technology the gases are burnt from top to bottom. Depending on the chemical composition of the waste gases, various reactions take place (oxidation, reduction, pyrolysis). A fluid wall/film prevents corrosion and deposition of particles in the reactor.

    In the washing column next to the reactor, soluble components are absorbed and particles suspended. The scrubbing liquid cools down and neutralises combustion products such as hydrogen halides. With the application of STYRAX within a holistic abatement concepts, manufacturers in the high-tech industry will meet the strict standards of the German air pollution law (TA Luft).

    The Alternative to Fuel Gas — STYRAX Plasma-Wet Abatement

    The STYRAX plasma scrubbers set new standards in waste gas treatment by using electrical energy directly and highly efficiently. Thanks to the integration of a powerful DC plasma torch and a 15 kW power supply, optimum energy yield is achieved.

    The proven reactor design and washing stage have been retained, making the STYRAX plasma scrubbers just as reliable and easy to maintain as their natural gas-powered predecessors. The footprint remains compact. At the same time, energy consumption has been reduced by an impressive 50%!

  • MBBR
    The MBBR process is a technology for biological wastewater treatment. In this process, microorganisms are cultivated as a biofilm on carrier material. They are responsible for the degradation of organic wastewater ingredients & nitrogen compounds....

  • Due to the microorganisms living in biofilms, the MBBR treatment process is also very robust and much more stable than other biological treatment technologies. MBBRs function well even under difficult conditions and recover very quickly after downtimes. This makes them a very resilient solution for industrial wastewater treatment. Whether new construction, expansion, optimization or service & maintenance of an existing wastewater treatment plant. We — the DAS Environmental Experts — take over all tasks as a full service provider.

    With SALVINIA you benefit from

    • low reactor volumes due to highly efficient carrier material
    • a strongly shortened engineering process and thus optimized costs & low time expenditure
    • reduced residual material
    • fast & uncomplicated performance optimization, for example in case of production increases (without any construction measures)
    • robust and stable treatment process, even under difficult conditions
    • fast recovery after downtimes
    • space-saving container design
    • simple cost reductions possible by using existing buildings
