Wastewater ponds - Wastewater treatment and recycling
In rural areas, several thousand non-aerated and aerated pond wastewater treatment plants are operated in Germany, and in some regions the share of wastewater treatment plants is still 30% or more. These ponds are mostly designed for sizes of less than 5.000 P.E. and a simple carbon decomposition and do not meet today's inflow loads and outflow requirements.
However, by cost-effective retrofitting of aerators and other components and adaptation of the process technology, the existing volumes can usually be expanded to further nutrient elimination and higher capacity without modifications. Based on numerous practical cases, ATB is able to offer a suitable expansion concept for practically every pond treatment plant with the corresponding technical equipment, on request also with a rental option for testing.
