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

Activated Sludge. The activated sludge is a process with high concentration of microorganisms, basically bacteria, protozoa and fungi, which are present as loose clumped mass of fine particles that are kept in suspension by stirring, with the aim of removing organic matter from wastewater. From: Resource-Efficient Technologies, 2016.

Xylem pumps for the sludge-handling market include: A full range of dry mounted and submersible non-clogging centrifugal pumps for use in sludge transport for up to 8% solids. Godwin Dri-Prime pumps transport raw sewage, sludge and fluids with solids up to 125 mm. Godwin Heidra pumps - reliable hydraulic submersible pumps.

Thickened Waste Activated Sludge Pumping Made Easier ith three major plant expansions since 1957, the City of Las Vegas Water Pollution Control Facility (WPCF) capacity has steadily increased. Because of this increase in population growth and treatment capacity, new equipment has been installed to further enhance the treat-ment of influent

The pumping of recirculated sludge in the comprehensive activated sludge technology exposes 1.5 ̶ 3% of the electric energy consumption of a wastewater treatment plant (WWT).

Vacuum pump for oxidation of activated sludge tank . Wastewater purification – Oxidation of activated sludge tank. More and more activated sludge tanks are being built to reduce the space requirements and cost of wastewater treatment plants. The introduction of oxygen is essential for wastewater purification.

Vacuum pump for oxidation of activated sludge tank-

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.

Clarifier Effluent: Activated Sludge Process Control

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.

Jan 01, 1985 Since the pump has no moving parts in contact with waste waters or sludge, practically, 521 Waste Water and Sludge Pumping it never fails. However, their efficiency is very low, ranging from 0.15 to moisture content, requiring continuous pumping (such as the return and excess sludge from activated sludge units).
