Screw Dehydrator Sludge Dewatering Cationic Polyacrylamide
Our cationic polyacrylamide, with high molecular weight and medium charge denstiy, it works for municipal water treatment, sludge dewatering with Belt filter press. It is used in various liquid solid separation systems in different industries. It is popular insludge dewatering process, raw water and waste water clarification.
Polyacrylamide (PAM) is a water-soluble polymer that is widely used as a flocculant in sewage treatment. The accumulation of PAM affects the formation of dewatered sludge and potentially produces
sludge dewatering chemical waste water treatment
Polyacrylamide in waste water treatment sludge dewatering processing. Main Production: 1. Oilfield Chemicals, Oilfield chemical is a general germ,The oilfield chemicals we can supply include anionic polyacrylamide used for oil drilling mud additives,drag reduction agent and EOR(enhanced oil recovery)agent .
Background Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land.

Cationic polyacrylamide has strong flocculation effect, it can adsorb the flocculent particles in the water, and make its rapid subsidence, so as to achieve the separation of mud. If the sludge dewatering process has no polyacrylamide, wastewater and sludge is a kind of mixed state because of its thickening enrichment work.

Polymeric flocculants in waste water treatment
Polymeric synthetic flocculants on the basis of polyacrylamide have opened new ways in waste water treatment and in sludge dewatering about 20 years ago. During this time the product development has made many progresses, and the application methods have increased, too.
Centrifugal sludge dewatering efficiency after CPAM conditioning . In this study, two series experiments were conducted. In the first experiment, the original sludge was conditioned using CPAM with 5 million MW and 60% CD at concentrations of 1, 2, 3, and 4 mg g −1.The conditioned sludge was then dewatered in a centrifuge at 1600×g for 300 s.

3, polyacrylamide and sludge mixture: polyacrylamide in the dehydration equipment at a certain location and sludge must be fully reacted, the occurrence of flocculation. To this end, the viscosity of the polyacrylamide solution must be appropriate, in the existing equipment conditions can be fully mixed with the sludge, the two mixed even if it
The effects of the molecular weight (MW) and charge density (CD) of cationic polyacrylamide (CPAM) on sludge dewatering and moisture evaporation were investigated in this study. Results indicated that in sludge conditioning, the optimum dosages were 10, 6, 6, 4, and 4 mg g−1 CPAM with 5 million MW and 20% CD, 5 million MW and 40% CD, 3 million MW and 40% CD, 8 million MW and 40% CD, and 5
- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- 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.
