How to Use Polyacrylamide for Water Treatment
Coagulation is all about changing a liquid to a solid or half-solid state by adding a specific chemical or coagulant. Polyacrylamide products also combine with water to produce insoluble hydroxides. This results in precipitation where the insoluble hydroxides combine to form meshes that can trap tiny particles into a more significant mass.

Why is polyacrylamide used in water treatment?
With the increasing global water scarcity and escalating environmental pollution, efficient water treatment has become paramount. Polyacrylamide, as a versatile polymer compound, has demonstrated significant achievements in the field of water treatment. PAM is widely used as a coagulant and flocculant in wastewater treatment.
What is polyacrylamide (PAM) used for?
In raw water treatment, polyacrylamide (PAM) is used together with activated carbon for the coagulation and clarification of suspended particles in domestic water; in sewage treatment, polyacrylamide (PAM) can be used for sludge dewatering; in industrial water treatment, polyacrylamide (PAM) is primarily used as a formula agent.
Can anionic polyacrylamide be used as coagulant aid with ferric sulphate and polyaluminium chloride?
It is important to point out that the optimal coagulant dose can be reduced when anionic polyacrylamide is used as coagulant aid with ferric sulphate and polyaluminium chloride, thus decreasing treatment costs. 3.10. Mechanisms of the process
What is polyacrylamide used for?
Polyacrylamide (PAM) is a collective term for polymers obtained by the homopolymerization or copolymerization of acrylamide monomers under the action of an initiator. It can be used as a coagulant, retention aid, sludge dewatering agent, and flocculant sedimentation agent, among other uses, and has a wide range of applications.
Why is polyacrylamide used as a flocculant?
Polyacrylamide (PAM) is a commonly used polymeric flocculant because it is possible to synthesize polyacrylamides (PAMs) with various functionalities (positive, neutral, or negative charge) which can be used to produce a good settling performance at relatively low cost.
