Determination Of Optimum Polymer Dose For Grand Forks Wastewater Treatment Plant Lagoon Sludge Dewatering
… will be dewatered and will be used beneficially. Polymers are used for coagulating sludge solid particles for better dewatering and bear a major part of cost associated with the dewatering process. So, choice of the appropriate polymer for dewatering and determining the optimum dose is very …

Municipal sludge dewatering using a belt filter press
… aerobically digested sludges to determine the optimum polymer conditioning for a belt filter press The optimum polymer dosages for all three zones of a belt filter press were compared with each other to determine the best overall conditioning. The requirements of all three zones of a belt …

The Effect of Cations on Volatile Solids Destruction, Odors, and Dewatering in anaerobic digestion
… with 30 days of SRT. Conditioning with cationic polymer and dewatering simulating a high solids centrifuge were performed after digestion. It was found that volatile solids destruction and volatile organic sulfur compounds generation increased proportionally as iron content in influent increased. …

Development and Evaluation of Ternary Amorphous Solid Dispersion of Poorly Water-soluble Compounds
… TASD containing CUR and RES with a hydrophilic polymer. Methods: Choosing an optimum polymer can be considered as one of the most crucial activities during TASD development. We carried out commonly used polymer screening studies i.e. miscibility, crystallization tendency, Flory-Huggins …

Effect of conditioning on the performance of a plate and frame filter press
… and aerobically digested sludges to determine optimum polymer dosages for various mixing intensities produced during conditioning by a high-stress mixing unit. Mean velocity gradient (G) values were established for each of the mixing speeds used ranging from 250 sec-1 to 4,000 sec-1. Using the …

The effect of polymer dose and mixing intensity on sludge dewatering with a plate and frame filter press
… filter press performance over a range of polymer doses and under a variety of sludge and polymer mixing conditions. In addition, bench-scale polymer dosing and mixing experiments were conducted with the same sludge samples to determine the relationship between the bench-scale tests and …

Anaerobic / Aerobic Digestion for Enhanced Solids and Nitrogen Removal
… the dewatering capabilities, with lower optimum polymer dose, reduced CST and increased cake solid concentration, and reduce the odor generation from the biosolids. Both An/Aer/Ana – A and An/Aer/An – B gave 70% VS removal, compared to 50% with single MAD and 62% with only Ana/Aer. COD …

Batch and continuous production of stable dense suspensions of drug nanoparticles in a wet stirred media mill
… To prevent aggregation of nanoparticles, polymers and surfactants are dissolved in water acting as stabilizers via adsorption onto the drug crystals. In the last two decades, ample experimental data were generated in the area of wet stirred media milling for the production of drug …
