ISEA Civil Waste water plants: Activated sludge

Activated sludge is one of our best methods to clean wastewater. This system is ideal for small and medium-sized communities as it is effortless to use and maintain and consumes less electricity.

Hence, this process relies on aerobic bacteria, where the bacteria feed off the organic contents that are present in the incoming wastewater. The activated sludge process is divided in two.

The first part is when air is injected into the waste using multiple fine bubble air diffuses (ISEA patented) feed through a micro-perforated EPDM diaphragm compressor that ensures the growth of the bacteria.

The second stage is when the larger sludge is separated from the effluent flows is part of it is recycled in the aeration section. Through the outfall, the surface water is taken out through hydraulic flux. After the water has reached a special still zone within the unit, the solids in the water are settled.

Another added benefit of this system is that overall efficiency can be improved by pre-treatment and post-treatment installations (depending on the water’s properties and the final destination). Consistent effluent properties and a high standard ensuring that all the water cleaned is of the highest quality and is adaptable to different types of grounds.
