In municipal sewage treatment plants, cationic polyacrylamide (CPAM) is commonly used for the clarification and dewatering process. When it comes to the deliming or flocculation stage, the concentration of the polyacrylamide solution is typically adjusted between 0.1% and 0.3% in the dosing system. This solution is then mixed with the sludge using a pump, which helps to create a more compact sludge mass before it is sent to the dewatering equipment. Throughout the process, operators continuously monitor the performance of the sludge removal and adjust the dosage accordingly to achieve optimal results based on real-time conditions at the site. This ensures that the system runs efficiently and maintains high-quality output.
