Waste activated and digested sludges are some other great applications for the double disc pump. This includes both transfer and dewatering feed applications. While the pump is a reciprocating pump, the short stroke length provides a very small displacement per revolution and therefore a relatively smooth flow that does not affect dewatering
Activated sludge process is a process for treating sewage and waste water commonly referred as effluent using bacteria (to degrade the biodegradable organics) and air (Oxygen for respiration).. Activated sludge refers to a mixture of microorganisms and suspended solids. The bacterial culture is cultivated in the treatment process to break down organic matter into carbon dioxide, water, and

The second approach to determine the best return activated sludge rate is by using the solids mass balance equation. Although it might sound complicated to some, in general, this is better than the earlier approach which is basically relying on crude observation. To determine the correct return flow rate, the equation below should apply.
operational adjustments can be directed to the specific treatment unit of the activated sludge system causing the problem. Making adjustments to one unit of the treatment system when the issue is located in another unit is a common mistake in troubleshooting the activated sludge process.
