poly aluminium chloride vs polyelectrolyte function
Polyelectrolyte - Wikipedia
IUPAC definition Polyelectrolyte: Polymer composed of macromolecules in which a substantial portion of the constitutional units contains ionic or ionizable groups, or both. [2] Notes: The terms polyelectrolyte, polymer electrolyte, and polymeric electrolyte should not be confused with the term solid polymer electrolyte.

Polyelectrolyte polymers—Types, forms, and function
Polyelectrolytes are macromolecules that, when dissolved in a polar solvent like water, have a (large) number of charged groups covalently linked to them. In general, polyelectrolytes may have various kinds of such groups. Homogeneous polyelectrolytes have only one kind of charged group, e. g. only carboxylate groups.

Polyaluminium Chloride - Process, Properties and Functions
Aluminium chlorohydrate is a group of salts having the general formula AlnCl (3n-m) (OH)m. It is used in deodorants and antiperspirants and as a flocculant in water purification. Other names for pac are basic aluminium chloride, polybasic aluminium chloride, aluminium hydroxide, and aluminium oxychloride and aluminium chlorohydrate.

Aluminium chlorohydrate - Wikipedia
Aluminium chlorohydrate is a group of water-soluble, [1] specific aluminium salts having the general formula Al n Cl 3n−m( O H)m. It is used in cosmetics as an antiperspirant and as a coagulant in water purification . In water purification, this compound is preferred in some cases because of its high charge, which makes it more effective at

What is Poly Aluminium Chloride - Monarch Chemicals
To get good results in drinking water treatment, where polyelectrolytes must be avoided for their mutagenic property, low aluminium-content and high basicity PAC 9%-10% Al 2 O 3 is employed. Usually, PAC 9%-10% Al 2 O 3 is produced by simple dilution of PAC 18% Al 2 O 3, adding a basifier like Na 2 CO 3, in order to reach a final basicity of 58

COMPARISON OF POLY ALUMINIUM CHLORIDE (PAC) AND ALUMINIUM
type often used is aluminum sulfate (aluminum) and poly aluminum chloride (PAC) (Wityasari, 2015). Coagulation is the addition of chemicals (coagulant) into the raw water with the aim of reducing the repulsion between colloidal particles, so that the particles can be joined into a floc-floc fine. While flocculation is a process

Coagulation and Flocculation in Water and Wastewater
The commonly used metal coagulants fall into two general categories: those based on aluminum and those based on iron. The aluminum coagulants include aluminum sulfate, aluminum chloride and sodium aluminate. The iron coagulants include ferric sulfate, ferrous sulfate, ferric chloride and ferric chloride sulfate.

Application of Organic Coagulants in Water and Wastewater
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.
