Water and Wastewater Treatment - Monroe Environmental

Thickeners Circular Thickeners are a crucial step between upstream process clarifiers/separators and downstream de–watering and sludge con-ditioning processes. A well designed thickener provides storage and equalization, and reduces the costs associated with de–watering. Thickeners are similar to other circular clarifiers in appearance

Wastewater Technology Fact Sheet: Sequencing Batch Reactors

As illustrated in Figure 1, the solids handling system may consist of a thickener and an aerobic digester. With SBRs there is no need for return activated sludge (RAS) pumps and primary sludge (PS) pumps like those associated with conventional activa ted sludge systems. With the SBR, there is typically only one sludge to handle. The need for

Sludge Thickening by Dissolved-Air Flotation

SLUDGE THICKENING BY DISSOLVED-AIR FLOTATION William J. Katz and Anthony Geinopolos Sludge thickening, as the name im plies, is a dewatering process.

Paint Sludge Skimmer | Aqurius Consult

The water to be treated is continuously taken from the tank located underneath the cabins or sludge pit. Water is delivered to the paint sludge skimmer system by a special pump. At the entry of the paint sludge skimmer system a static mixer is installed. The flocculent is dosed at the inlet of this mixer with the help of a dosing pump.

In these tanks, sludge flows into the tank, from either a periodic or continuous removal of sludge from the sedimentation basin, until the thickening tank is full. The sludge is allowed to quiescently settle and a telescoping decant pipe is used to remove supernatant.The decant pipe may be continually low-ered as the solids settle until the desired solids concentration is reached or the sludge will not thicken further.The thickened sludge …
