Is polyaluminium chloride better than polyelectrolyte – alum-based coagulation?

At the Barekese Water Treatment Plant in Ghana, an alternative, the polyelectrolyte – polyaluminium chloride (PAC) is also used in coagulation but limited information is available on the operating conditions required to achieve better performance than alum-based coagulation.

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 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.

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 is the molecular formula of Pam?

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. It readily dissolved in water to form a viscous, colorless solution.

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.
