Alfa Laval - Sludge dewatering and thickening
The liquid content of sludge from municipal water / wastewater and industrial wastewater treatment has a high impact on treatment and disposal costs. Alfa Laval supplies a variety of thickening and dewatering technology options, as well as advanced control systems, that are designed for optimizing plant performance and reducing total cost of
Thickening. Gravity sludge thickeners are an easy and cost-effective approach to minimizing the volume of waste solids. Our experts size thickeners to achieve the highest concentration of sludge with the smallest footprint.
Sludge Thickening - Huber Technology China
Innovative high qualitative machines, plants and stainless steel equipment for municipal and industrial water, wastewater and sludge treatment. Competent in stainless steel - leading in wastewater technology - more than 45,000 installations worldwide. Read more
Thickening and dewatering - Reduce the amount of waste for disposal by up to 90%. On-site thickening and dewatering of sludge is a fundamental part of all current wastewater treatment options to significantly reduce the sludge volume. This has a huge impact on costs for transportation, effluent disposal, storage and drying.
What is the Sludge Thickening Process in Water Treatment
Sludge contains biosolids that have been removed from liquid sewage. Sludge thickening is the process used in wastewater treatment centers to increase the solids concentration and decrease free water. This step minimizes the load on sludge dewatering and digestion.

Sludge Thickening - an overview | ScienceDirect Topics
Centrifuges, which are devices that amplify the forces at work in gravity separation, are of several different types. Centrifuges are used for separation of grit and other relatively heavy solids at the head end of wastewater treatment facilities, as well as for sludge thickening and/or dewatering at the “other end” of such facilities.
Municipal Wastewater and Sludge Treatment 49 Secondary municipal wastewater treatment is almost always accomplished by using a biological treatment process. Microorganisms in suspension (in the "activated sludge" process), attached to media (in a "trickling filter" or one of its variations), or in ponds or other processes are used to remove
Sludge Thickening Technologies Reduce Wastewater COD
Sludge Thickening. The thickening of activated sludge is a common practice many wastewater treatment plants. These plants use a biological treatment process to reduce the wastewater COD and BOD before discharging downstream into the environment.
For the dewatering and thickening of sewage sludge, industrial centrifuges are now considered the state of the art. They are cost-effective, energy-saving and efficient. Flottweg has over 50 years of experience in dewatering and thickening of sewage sludge. We are aware of the special requirements of sewage treatment plants and the water industry.
Global Municipal and Industrial Sludge Treatment Market
Sludge obtained as by-product from industrial chemicals and waste treatment is known as industrial sludge. Activated sludge is used for the treatment of municipal sewage therefore also known as biosolid as it mainly consists of biological solids. Sludge management is the important part of the wastewater treatment process.
Wastewater treatment has been called "a sludge generation industry." Sludge is a byproduct of any treatment process, so managing the quantity and disposal is vital.
- Which polymer thickening agent is a cationic polyacrylamide?
- Zhang et al. , synthesized the polymer thickening agent DXGY-1, which is a cationic polyacrylamide. Its viscosity retention ratio in 12% HCl + 3% HF reached 82%. Liu et al. , synthesized a copolymer from AM, DMDAAC, and AMPS monomers and a cationic monomer X.
- Which polymer is used as thickener in the presence of Ca2+ or Na+?
- Hydrophobic-associated polymer is widely used as thickener in the presence of Ca 2+ or Na +. Three polymers including partially hydrolyzed polyacrylamide (HPAM) and hydrophobically associating polymers (CHAP and CBHAP) were used to clarify the thickening mechanism.
- Which polymer is used to produce partially hydrolyzed polyacrylamide (HPAM)?
- PAM is used to produce partially hydrolyzed polyacrylamide (HPAM), which is linear, anionic, water-soluble, stable, polymeric, and high molecular weight chain of acrylamide (C 3 H 5 NO) monomers (Bao et al., 2010; Braun et al., 2025; Liu et al., 2016; Xiong et al., 2018).
- Can polyacrylamide be used as a thickener in water-based fracturing fluids?
- Polyacrylamide (HPAM) is commonly used as a thickener in water-based fracturing fluids due to its good solubility and thickening ability. However, drawbacks such as the formation of high temperature and high salinity in oil and gas production currently limit its use as a thickening agent for fracturing fluids.
