EFFICIENT CIRCULATION AERATION SYSTEM FOR OPTIMIZING THE BIOLOGICAL WASTE WATER PURIFICATION IN LARGE BASIN VOLUMES
A flow guiding tube placed in the middle of the basin with a free space to the basin bottom and water surface
Creation of a bottom flow current to the basin center and backflow at the upper water layer
The installation consists of a circulating mixing device with flow guiding pipe, central air distribution and ventilation units mounted on the circular ring floor
Slow-running 3-bladed large mixer with high flow rate for deposit-free and floccules preserving circulation
Guiding pipe for generating a low-loss vertical flow and improving the bottom speed
