Activated sludge models now in use worldwide for the design and operation of treatment
systems use hypothetical concentrations of active organisms. In order to validate and
calibrate model outputs, concentrations and ...
Atmospheric nitrogen pollution is on the increase and human activities are directly or indirectly responsible for the generation of the various nitrogen polluting compounds. This can lead to the two major problems of ...
Activated sludge flocs are responsible for flocculation, settling and dewaterability. It is important to maintain the growth off loc-forming bacteria for efficient sludge settleability and compaction for good quality ...
