Quaternization-based graft modification of straw fibers for conditioning the sludge dewatering performance

Water Science and Technology
Extracellular polymeric substances (EPS) are a critical influencing factor in sludge dewatering. Disrupting such EPS contributes to the release of bound water in sludge, enhancing the sludge dewatering performance. In This study, quaternized straw fibers

Real-Time Sensor-Controlled Coagulant Dosing and Pressure in a Novel Sludge Dewatering System

Clean Technologies
Sludge dewatering remains a resource-intensive process, often constrained by high residual moisture content and inefficient chemical conditioning. Conventional systems typically rely on fixed polymer dosages and predetermined filtration pressures, which ...

In-line Sludge Dewatering 

, 2019
This paper summarizes the work done to show a proof of concept for an in-line sludge dewatering system. First, the design of the system is described, including the selection of materials, devices, and simulated sludge used to test this concept. The different materials and processes considered for each element are described in the System Design section.

Chemical conditioning of aerobically digested sludge using polyelectrolytes with different charge densities

Applied Water Science
This research was carried out to evaluate the effects of different dosages (1.85–4.44 g kg−1 Ts−1) of three cationic polyelectrolytes with charge densities (CD) of 20%, 40%, and 60% on the dewatering properties of an aerobically digested sludge.
