Polyacrylamide (PAM) is a water-soluble flocculant polymer. Flocculation is a water treatment process where solids are grouped into later flocs so that they can be removed from water. Sometimes the process happens naturally, other times it occurs through the use of chemicals such as PAM.
Polyacrylamide PAM for water treatment is formed through the polymerization of acrylamide. The main role of PAM is to coagulate or flocculate solid matter in a liquid. This is why it is best used for water treatment. This flocculant polymer is produced and sold in several forms, including;
• Non-anionic.
• Ionic polyacrylamide.
PAM for water treatment
PAM is majorly used in water treatment applications. These include industrial water purification, wastewater treatment, sewage treatment, and drainage purification. It is also used in soil conditioning, molecular biology labs and the fossil fuel industry. Here are the benefits of using PAM for water treatment;
• Anti-scaling and anti-corrosion of circulating systems.
• Improving floc strength and settling velocity.
• Improving water quality.
• Reducing the amount of flocculant.
PAM is perfect for water treatment due to its ability to promote flocculation and increase the viscosity of particles. Just to reiterate, flocculation refers to a process where solid particles precipitate in a liquid to form a floc or clump. PAM products mix with water to form insoluble hydroxides.
This is an important process in water treatment. Because of its coagulation capabilities, PAM remains the best option for water purification. Coagulation refers to the process of changing fluid to a half-solid or solid state using a specific coagulant or chemical.
To correctly use PAM for your water purification needs, you must put into consideration the kind of wastewater you are working with. You will need to know the impurities and other solid particles in the water you are treating. This knowledge will guide the entire procedure as well as inform the correct PAM dosage.
Superb Combo: PAM/PAC Water Treatment
PAC chemical is a water-soluble and inorganic chemical with a polymeric structure. Using PAM together with PAC will help you meet your purification needs. This combination works well for sewage treatment, industrial water treatment, and the purification of urban drainage systems.
Using PAM with PAC will help you attain desired results. Let’s say we are treating sewage water, using either one of the two alone will not get rid of all the impurities. This is due to the high levels of organic matter and sludge found in sewage.
Introducing an extra chemical like, PAC (an inorganic flocculant) can help rid the organic matter much faster. However, you need to be aware of the procedure of addition and intervals of your dosages.
Choosing The Right Type of Polyacrylamide
There are 2 common types of PAM flocculant, which include inorganic and organic. The type you select depends on the quality of the wastewater you intend to treat. Choose inorganic PAM for fast flocculation. That’s because it works best for colloid concentrated liquids.
A colloid in this case refers to an element made of particles bigger than atoms and molecules but invisible to the human eye. For small flocculation, other coagulation agents, together with PAM, can be used. Organic polyacrylamide is the ideal option in such a situation.
