The municipal wastewater treatment plant utilizes cationic polyacrylamide (CPAM) to enhance the dewatering process. When it comes to de-liming, the plant currently adjusts the CPAM concentration in the dosing system to between 0.1% and 0.3%. This solution is then mixed with sludge using a pump, and the resulting mixture is sent to a centrifuge for effective dehydration. Throughout the process, the concentration of the polymer is continuously adjusted based on the performance of the sludge output and the specific conditions at the site. Operators regularly fine-tune the dosage to ensure optimal results and efficiency. This real-time adjustment helps maintain consistent quality and performance, making the treatment process more reliable and cost-effective.
