Polyaluminium chloride as an alternative to alum for the

The efficiency of various polyaluminium chloride coagulants (PACls) was compared to the efficiency of aluminium sulfate (alum) in the coagulation-flocculation process preceding direct filtration in drinking water treatment. The comparative study consisted of two separate yet complementary series of ¡­

Suitability of Highly Polymerised Polyaluminium Chlorides

Among them, polyaluminium chloride is the most widely used in water purification due to its fast flocculation speed and large floc size [1,2,3,4,5,6,7]. In water treatment plants, in order to improve the efficiency of coagulation process, the use of prehydrolysed coagulants in place of aluminium sulphate (VI) is a common practice.

What is Poly Aluminium Chloride - Monarch Chemicals

Poly Aluminium Chloride (PAC) is most commonly used in the water treatment industry as a coagulant. It is characterised by the degree of basification ¨C the higher this number the higher the polymer content which equals a more efficient product in the clarification of water products. Other uses of PAC include within the oil and gas industries

Preparation and Characteristics of Polyaluminium Chloride by

OH ? is the basic component influencing the morphology of polyaluminium chloride [6¨C9] whose index in PAC is measured by basicity (B). According to GB 15892-2003 (water treatment chemical-polyaluminium chloride) , basicity can be measured. The mol percentage of OH and Al in PAC is defined as basicity and this parameter can reflect the

Coagulation behavior of polyaluminum chloride: Effects of pH

1. Introduction Coagulation mechanisms may be different under different coagulation conditions for metal salt coagulants, such as double-layer compression [1], charge neutralization [2], [3], and sweep coagulation [3], [4]. Charge neutralization and sweep coagulation are the most important coagulation processes.

Study of production 500 kg/batch polyaluminum chloride from

A pilot-scale experiment with a capacity of 500 kg/batch feed was conducted by reacting Al (OH) 3 with HCl and H 2 SO 4, then neutralized using CaCO 3 to obtain liquid PAC and gypsum as a by-product. The variation of acid concentration as reactant and reaction time were conducted to determine its effect on the composition of PAC and the amount

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
