The return sludge pump moves sludge from the settling tank back to the aeration tank. This circulation is essential for maintaining the concentration of microorganisms that treat the wastewater. The pump's efficiency directly impacts the …

Sulzer has a range of pumps that can be used successfully for the return of activated sludge. The submersible sewage pump type ABS XFP, submersible mixed flow pump type ABS AFLX and submersible propeller pump type ABS VUPX are all well suited to this application.

In return-activated sludge (RAS) and waste-activated sludge (WAS) applications, pumps and mixers are vital components of the wastewater treatment process. High flows at a low head are characteristic of this application requiring pumps to pass all solids encountered without clogging.

In order to determine and come up with the ideal sludge return flow rate or RAS, you will need an indicator that can tell you what is needed to be done. Basically the main consideration on what everyone is using is by referring to the Solids Level in the wastewater system.

It includes return activated sludge (RAS), which is continuously pumped back into the secondary biological treatment tank as part of the treatment process, and waste activated sludge (WAS), which is excess from settled sludge that is pumped to the sludge handling process.

2019年10月31日 · Return Activated Sludge (RAS) In short, RAS is used in biological treatment and prevents the loss of microbes within sludge which help decompose and purify effluent. Excess sludge that is generated in the biological process can be transferred to a sludge treatment facility for management.

Return Activated Sludge Pump. An activated sludge process refers to a multi-chamber reactor unit that makes use of highly concentrated microorganisms to degrade organics and remove nutrients from wastewater to produce a high-quality effluent.

The Liberty Process G090G1L Progressive Cavity Pump is designed for activated sludge pumping for liquids with high biosolids content or heavy waste solids in the (RAS) Return Activated Sludge process in wastewater treatment facilities.

The G090G1L is a standard ANSI flanged pump design manufactured with high strength cast Iron or 316 Stainless Steel pump casings and designed in 1, 2 and up to 4 stages for 85, 170, and 350 psi discharge pressures making it an ideal low-cost, maintenance free drop-in replacement pump.

QJB-W sludge return pump is a new product developed on the basis of submersible mixer production technology. This pump is a special equipment for mixed liquid return, denitrification and denitrification of secondary sewage treatment plants. It can also be used for pumping and purifying ground drainage.
