You can treat your wastewater efficiently and environmentally responsibly in a state-of-the-art two-stage activated sludge process at one of Germany's largest industrial wastewater treatment plants (WTP). We accept wastewater at the property lines in Industriepark Höchst and capture all the information needed for billing.
To verify the biodegradability of your wastewater and aqueous waste, we analyze a representative sample before the first disposal run. Your role is simple: you just tell us about the process that generates the wastewater or aqueous waste. With these steps, your waste is sure to be disposed of safely without risk to human health or the environment.
We accept wastewater through the local sewer system as well as vacuum truck deliveries.
Any remaining sewage sludge is taken to our sewage sludge incineration plant for disposal.
