The new life of traditional water treatment flocculant

They are effective over a broader pH range compared to alum and experience shows that PACl works satisfactorily over a pH range of 5.0 to 8.0. Another important advantage of using polyaluminium coagulants in water treatment processes is the reduced concentration of sulphate added to the treated water.

Jun 1, 2015 · PACl has many benefits over conventional hydrolyzing aluminum or iron salts, such as better performance at low temperature [17], [18], less aluminum residuals [19], less sludge volume [20], less effect on the pH value of raw water [8], [21], and more rapid flocculation [21].

DelPAC 2020, when used as a coagulant, can provide longer filter runs, reduce or eliminate the need of alkali for pH adjustment, lower amounts of residuals and generally has a lower overall cost when compared to other treatment programs.

Polyaluminium Chloride in Water Treatment - Dia-Chemical

Polyaluminium chloride PAC is a kind of water treatment chemical with a wide range of uses. It has the advantages of fast flocculation, rapid sedimentation, good solubility and low water purification cost. As a reliable polyaluminium chloride manufacturer in China, we can guarantee the high quality and competitive price.

Poly Aluminium Chloride (PAC) - Water Treatment Chemical

Description: Poly aluminium chloride (PAC) , the white or yellow powder, is an inorganic polymer coagulant. Compared with traditional inorganic coagulants, fengbai poly aluminum chloride flocculation precipitation speed is fast, the PH value applicable range is wide, water purification effect is obvious and non-corrosive to pipeline equipment.
