Water | Free Full-Text | Optimizing the Flocculation Effect

Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM. In this paper, the optimal flocculation conditions of a novel CPAM were

In recent years, research on the synthesis of CPAM has been ongoing and widely used in wastewater treatment. For example, Ma et al. (2017b) synthesized a new type of CPAM by homogeneous polymerization, with monomers such as dimethyldiallylammonium chloride (DMDAAC) and AM. It works well in removing kaolinite suspended particles.

Research on a new cationic polyacrylamide (CPAM) with a

Flocculation is one of the commonly used sludge conditioning methods in water supply plants, which can improve the sludge dewatering performance by reducing the specific resistance of sludge (SRF), decreasing the amount of sludge, and finally lowering the transportation cost and subsequent disposal cost of sludge. Therefore, it is particularly important to develop new and efficient flocculants

Deep dewatering process of sludge by chemical conditioning

FeCl 3, quick lime, and cationic polyacrylamide (CPAM) were used for excess sludge conditioning from wastewater treatment plant (WWTP) and the dewatering performance by different chemical conditioners was investigated. Experimental results showed that FeCl 3 could make small and concentrated sludge particles.
