Optimization of wastewater treatment processes

Wastewater treatment plants (WWTP) are common practice in Germany. When the plant is designed, discharge values form the basis for the requirements as the plant is subject to the emission limit requirements for the discharge of treated wastewater into the receiving water. Hence, most plants run in their original design without any attempt to optimize them. Nevertheless, the analysis often shows a potential increase in wastewater treatment efficiency as well as possibilities to reduce operating costs.
