poly-aluminium-chloride (pac) - 3v tech

Poly-Aluminium-Chloride (PAC) - 3V Tech

The polymer hydrolyzes completely in treated water, leaving low residual aluminium content, less than 100 ppb with a dosage of 20 ppm, whereas standard PAC 9-10% HB leaves approx. 200 ppb aluminium ions. Our PAC 9HB forms large flakes which easily sediment, reducing the backwashing of sand filters and decanters.

Poly-Aluminium Chloride(PAC) - ChemBK

Poly aluminum chloride is a water purification material, inorganic polymer coagulant, also referred to as Poly aluminum, abbreviated as PAC, an inorganic polymer water treatment agent having a relatively large molecular weight and a relatively high charge is produced due to bridging action of hydroxide ions and polymerization of polyvalent anions.

A Comparative Study of the Performance of Polyaluminum

Polyaluminum chloride (PAC)/natural polyelectrolyte composite coagulants have received considerable attention recently due to their exceptional properties in drinking water treatment. However, the criteria for selecting polyelectrolytes grafted into the PAC to improve coagulation performance are not yet well defined. For this purpose, we have compared the potential of composite coagulant PAC

The new life of traditional water treatment flocculant polyaluminum

Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used flocculation material for water treatment. In this work, PAC has been used as a Lewis acid catalyst in inte

Alternative cost-effective preparation method of polyaluminium chloride

An alternative preparation procedure for polyaluminium chloride (PAC), a common inorganic coagulant, is presented in this paper. The proposed procedure is based on the use of granular aluminium metal, a common by-product of several aluminium-processing secondary industries, instead of using Al 2 O 3 (or of using a mineral containing Al 2 O 3) which is commonly applied by most industrial
