For agricultural farm wastewater treatment, cationic polyacrylamide (CPAM) is a commonly used treatment agent. It has good flocculation and sedimentation effects, helping to remove suspended particles and organic pollutants from wastewater.

Regarding the specific technical parameters and usage requirements of cationic polyacrylamide (CPAM), the following is the general guidance range:

1. Molecular weight (molecular weight): usually between millions and tens of millions, depending on wastewater characteristics and treatment requirements. Higher molecular weights generally work better with turbid wastewater.

2. Solid content: usually between 0.1% and 0.5%, also depends on the treated wastewater load and the characteristics of the original wastewater. Solids content that is too high or too low may affect the effectiveness of the dose.

3. Water solubility: Cationic polyacrylamide should be able to dissolve quickly in water and have stable dissolution properties in order to effectively interact with pollutants in wastewater.

Please note that the specific dosage and treatment methods should be adjusted and determined based on the characteristics of the wastewater, the requirements of the treatment equipment and operating guidelines. The best treatment solution can be determined by contacting Shandong Welldone Polyacrylamide (PAM) factory through laboratory testing and sample practice. 🌾🐟💧
