All this makes DAS Environmental Expert one of the leading companies in its sector and a reliable ESG partner for industrial companies.

Innovative waste gas treatment systems at the point of use

Point-of-use waste gas abatement systems of DAS Environmental Experts treat process gases as they accrue e.g. in the semiconductor, photovoltaic, LED and TFT industry. DAS scrubbers treat condensable, flammable, corrosive, reactive, toxic and/or pyrophoric gases and fine dust. Our process portfolio includes burn/wet systems, wet scrubber, pyrolysis and electrostatic filters.

Efficient and scalable plants for water treatment

DAS Environmental Experts water treatment plants use mechanical, biological and/or chemical-physical processes to bring the specific pollutants in industrial wastewater within the permissible limits. DAS EE solutions are always a perfect fit – regardless of whether a single wastewater treatment stage is to be installed or an entire factory is to be equipped with systems for the treatment of process , industrial or wastewater.

DAS wastewater solutions in high-tech manufacturing include:

• Removal of organic contaminants, measured as chemical oxygen demand (COD) and biochemical oxygen demand (BOD), from wastewaters
• Removal of heavy metals or other toxic compounds
• Treatment of chemical mechanical polishing/planarization (CMP) wastewater
• Treatment of silicon waste
• Treatment and polishing of wastewater containing fluoride and arsenic
• Treatment of isopropanol (IPA) or other volatile organic compounds (VOCs)
• Reuse of treated wastewater (water recycling)
• Recovery and recycling of valuable metals from wastewater
