What is the Sludge Thickening Process in Water …
Sludge thickening is an important process in treating solid waste. It minimizes the water waste, enabling the re-treatment of biosolids so that they can safely circulate back to waterways. It is vital to use the correct product and municipal wastewater treatment solution, so having an expert on hand will give your company the safeguards of dealing with the process in a safe manner.

The most significant variables that affect dewatering performance of a belt filter press are the sludge sludge characteristics, polymer conditioning, sludge feed rare, belt tension, and belt speed. The characteristics of greatest importance in wastewater sludges are the solids concentration, the nature if the solids, and prior biological or chemical conditioning.

Rotating biological contactors (RBC) are a conventional aerobic biological wastewater treatment unit. Conventional biological treatment means activated sludge systems and fixed film systems such as trickling filters, or RBC (NOLDE 1996). The advantage of all these systems is that they are compact (i.e. in densely populated urban settings) and that they efficiently reduce organic matter ...

How Viscosity Affects Pumping | Pumps & Systems
To understand how the viscosity of a liquid affects a pumping system, it is important to understand what viscosity represents. By definition, viscosity is the property of a liquid that causes it to offer resistance to shear stress such as that caused by liquid flow, primarily in the area of the pipe wall.
