Feb 10, 2021 Activated sludge systems are equipped with plain settling tanks designed to provide approximately 2 to 4 hours of hydraulic detention time. Return Sludge & Activated Sludge. The return sludge system includes pumps, a timer or variable speed drive, and a flow measurement device. An activated sludge system consists of the same components but in

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

Dec 04, 2015 (j) Return Sludge Pumping Capacity. (1) The capacity of a return sludge pumping system must be calculated based on the area of the activated sludge clarifier or clarifiers, including the stilling well area. (2) The return sludge pumping capacity must be equal to or greater than

The Sykes sludge pump range is specifically designed for applications where the fluid to be moved has a higher viscosity than water and/or contains solids up to 65mm.Especially effective in returning activated sludge in wastewater treatment works, temporary sewage bypass pumping and emptying polluted excavations or tanks, these units are robust in design and capable of delivering months of

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.
