Polyacrylamide as a flocculant, its role is generally for colloidal particles corresponding to the double layer of contraction, bridge, squeeze sediment, forcing colloidal particles to reach a stable state, and finally achieve the purpose of centralized sedimentation.
Cationic polyacrylamide is a kind of water-soluble linear polymer, in acidic or alkaline medium it is electropositive, it can effectively suspended particles with negatively charged of sewage
flocculation, and also has the characteristics such as decoloring, adsorption, and so on.

Application Scope
1.As a flocculant, cationic polyacrylamide is mainly used in industrial solid-liquid separation process, including sedimentation, clarification, concentration and sludge dewatering process.
2.The main industries of application are: municipal sewage treatment, papermaking industry, food processing industry, petrochemical industry, metallurgy industry, mineral processing industry, dyeing industry and sugar industry and various industrial wastewater treatment.
3.Used in sewage and meat, poultry, food processing wastewater treatment process sludge precipitation and sludge dewatering, promote colloidal particles aggregated into large floccule, separated from its suspension. The effect is obvious and the dosage is small.
4.It can also be used as mud treatment agent in oilfield development process, selective water blocking agent, water injection thickening agent, softener of textile printing and dyeing process , electrostatic prevention agent and general sterilization, disinfectant, etc.

How To Use
1. Dissolution: Dissolve solid PAMto 1‰—5‰ water solution before using. When dosage, it should be added into water slowly to ensure that the chemical can be dissolved
2. Solution dosage: Normallythe water solution is 1‰—5‰, but with high concentration and high viscosity suspension, it is advised to dilute water solution to 0.1‰ to get a better (Trying to avoid using high-shear centrifugal pumps to dissolve the solution to prevent the molecular chain from being cut)
3. Compared with anionic PAM, cationic onehas lower molecular weight, so does the Therefore, cationic and nonionic PAM have higher concentration ratio than anionic PAM. Recommended concentration is 1‰—5‰.
