Wastewater Ponds

Small wastewater ponds, built as decentralized plants without aeration systems, are many times used in remote sites for the treatment of municipal wastewater. By overloaded wastewater ponds the degradation capacity can be improved by using artificial aeration systems. Moreover, the area of a planed wastewater pond can be considerably reduced compared with that of a naturally aerated pond. Up to now only stationary operated aeration systems have been used, which are connected to the electricity grid. Where this connection is lacking, the use of decentralized, renewable energy systems is a sensible alternative.
