What is the Sludge Thickening Process in Water Treatment

Mar 06, 2018· Sludge thickening is important because it is the process used in wastewater treatment centers to increase the solids concentration and decrease the free water. This step minimizes the load on the downstream processes, such as sludge dewatering and digestion.

Introduction to sludge thickening Sludge Processing

A number of processes act to remove water from sludge to reduce its volume. As a result, the suspended solids concentration of the sludge is increased and the sludge becomes consolidated. These processes are referred to as either thickening or dewatering.

Sludge Thickening,Sludge Thickening Process,Thickening Process

Sludge Thickening Sludge thickening is a a low investment process used commonly in wastewater treatment plants to remove as much water as possible from the liquid sludge. The method involves increasing the concentration of the solids in the sludge so that they can be easily dewatered. Generally, a thickening device is used or alternately, a

Sludge Thickening an overview ScienceDirect Topics

In a well-operated thickener, the supernatant is normally of an acceptable chemical and physical quality for recycling to the treatment process, but the potential risk of microorganism and microanimal return in clarifier sludge is far greater than in the case of recycling used filter washwater.

Sludge thickening dewatering process of various sludge

Aug 13, 2019· Sludge thickening dewatering process of various sludge types. published date: 08-13-2019. STP typically requires sludge dewatering prior to final disposal of sludge/biosolids, or as a prelude to further processing or stabilization. Since the dewatering process has significant differences in reducing the moisture content of the sludge, the final sludge treatment method usually has a

Sludge Thickening and Dewatering Sludge Treatment System

Sludge thickening and dewatering is two important stages in treating sludge. Thickening is the first step of sludge treatment in which the solids concentration is increased and the total sludge volume is correspondingly decreased, Thickening commonly produces sludge solids concentrations between 15% and 20%, LZZG Deep Cone Thickener results in maximum water recovery, maximum underflow

Fact Sheet: Centrifuge Thickening and Dewatering

Jun 17, 2020· Centrifugal thickening and dewatering of sewage sludge is a high speed process that uses the force from rapid rotation of a cylindrical bowl to separate wastewater solids from liquid to produce a non-liquid material referred to as “cake.”

WasteWater System: Centrifugal Sludge Thickening Process

Therefore, Sludge Thickening Process is always looked upon as a cost effective related method that is used to remove more liquid content in order to increase the solid fraction. Sludge thickening using centrifugal force is one of the common processes that can be applied to reduce the water content and thus thickens the sludge.
