What is anionic Pam used for?

Anionic PAM: It is widely used in waste water treatment of chemical industry, municipal sewage treatment, such as coal washing, mineral processing, metallurgy, iron and steel industry and electronic industry. It is also used in oil industry to enhance oil recovery which is widely used.

What is anionic polyacrylamide (PAM)?

Anionic polyacrylamide (PAM) possesses interconnected and active groups that establish robust bonds with the surface of suspended colloids, promoting the formation of coarse particles among the suspended solids and a mixture of insoluble particles in water (Irfan et al. 2017).

What is cationic Pam used for?

Cationic PAM: It is very efficient in usage and has high dehydration rate. It is used for the waste water treatment in alcohol factory, monosodium glutamate factory, sugar factory, beverage factory, tanneries, dyeing and other fields. It has a better effect to be used together with inorganic coagulant in particular.

Is Pam a corrosive substance?

PAM is a dry white or light yellow powder similar in shape to table salt. It readily dissolved in water to form a viscous, colorless solution. It is non-toxic, non-corrosive, non-hazardous, and easily decomposes into its base elements of Carbon, Nitrogen and Oxygen at temperatures more than 120°C.

What happens when Pam reacts with metal cations?

Under low pH conditions, anionic PAM molecules react with metal cations, forming insoluble metal complexes. Conversely, in alkaline conditions, the coagulant adsorbs organic matter within flocs created from metal hydroxides, facilitating settling (Kumar et al. 2010; El-Naas et al. 2010).

Is polyacrylamide a flocculant?

Polyacrylamide (PAM), often referred to as “polymer” or “flocculant”. It is a long chain, linear organic polymer made up of individual monomer units with the molecular formula of C3H5NO and molecular weights ranging from 3,000,000 to 30,000,000 Daltons. PAM is a dry white or light yellow powder similar in shape to table salt.
