Polymers are effective for use as flocculants because they consist of long chains of molecules called monomers. Monomers can create bridges between solids particles (see Figure 3). Polymers can have different charges, charge densities, and molecular weights. Polymers that have a positive charge (otherwise known as cationic) and a high

optimization of polymer dose based on residual polymer

Optimization of Polymer Dose Based on Residual Polymer

Optimization of sludge conditioning and dewatering is a continuing challenge for wastewater treatment plants. This study investigated the use of an in-line UV¨Cvis spectrophotometer to optimize the polymer dose during sludge dewatering. The study established a relationship between the optimum polymer dose and residual polymer concentration in filtrate using UV¨Cvis absorbance measurements at

Advancement in Sewage Sludge Dewatering with Hydrate Crystal

Sludge dewatering plays a crucial role in reducing the sludge volume, facilitating transportation, and enhancing energy recovery. However, conventional mechanical dewatering methods often generate high-concentration organic wastewater containing toxic substances and decrease the caloric value of sludge. To address this challenge, a hydrate-based method was proposed as a solution for both

This was helpful for reducing the hydrophilicity of flocs and improved sludge dewatering performance. Meanwhile, for EPS content decreased slightly with CPAM addition, polysaccharide and protein content had no change, implying that CPAM has slight destruction on the EPS of sludge.
