Polyacrylamide resin (PAM) is a type of water-soluble polymer that is widely used in water treatment applications. PAM is made by the polymerization of acrylamide monomers, which results in a long chain polymer with high molecular weight.
In water treatment PAM can be used as a flocculant to enhance the efficiency of the liquid/solid separation process. PAM can help to remove suspended solids and other impurities from water by forming flocs, which are larger particles that can be easily removed through precipitation, sedimentation or filtration.
PAM is often used in conjunction with other chemicals, such as coagulants or pH adjusters, to optimize the water treatment process. The specific application and dosage of PAM will depend on factors such as water quality, flow rate, nature and concentration of the suspended solids to be recovered from the water stream and system design.
One of the advantages of using PAM in water treatment is that it is a highly effective and efficient treatment method. PAM can help to reduce the amount of iron and aluminum based chemical coagulants required for water treatment and can also help to improve the overall efficiency of the treatment process.PAM is usually effective at a fraction of the coagulant dosage necessary to obtain satisfactory results.
It is important to use PAM properly and follow appropriate guidelines to minimize any negative environmental impacts. PAM can be toxic to aquatic organisms in high concentrations, so it is important to carefully control the dosage and concentration of PAM used in water treatment. Most suppliers publish Safety Data Sheets, technical information bulletins and product data sheets which provide valuable information about the feeding, handling, storage and disposal of PAM.
PAM is a widely used and effective water treatment chemical that can help to improve the quality of water and optimize the water treatment process in a safe and cost effective manner. The manufacturer can provide further recommendations.
