1. First, conduct laboratory analysis. If the solid-liquid surface potential of the suspended matter is negative (generally negative), the PAC+CPAM scheme can be used.
2. Determine the PAC dosage: A dosage test needs to be conducted in the laboratory to determine the dosage and turbidity removal effect curve when PAC is used alone.
3. If the optimal dosage for PAC used alone is A, the actual dosage can be set at 1/4 to 1/3 of A, with the remaining work handled by CPAM.
4. Determine the PAC to CPAM addition ratio in the laboratory: Given a PAC dosage of 1/3 of A, determine the optimal amount of CPAM needed to bridge the PAC's coagulation effect. The optimal PAC to CPAM addition ratio should be determined through experimentation.
These steps will enable wastewater treatment companies to achieve optimal results and the lowest flocculation costs. This is a universally recognized high-efficiency, low-cost combination.
