suitability of highly polymerised polyaluminium chlorides

there are various types of prepolymerised coagulants, such as polyaluminium chloride (pac), polysilicic acid (psi) and polyferric sulfate (pfs). 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

high-poly-aluminum chloride sulfate coagulants and their,charge neutralization ability of inorganic polymer coagulant reached a certain level, polymerization degree of the inorganic polymer coagulant would be the decisive factor affecting the coagulation efficiency. zhao et al.21 obtained a polyaluminum chloride solution with an al c content of 81% by membrane distillation. the importance of al

polyaluminium chloride in water treatment dia-chemical

polyaluminium chloride, or pac for short, is a chemical compound used during water treatment process. it is an acidic solution made from aluminium, chlorine, hydrogen and oxygen, and act as coagulating agent. polyaluminium chloride is a safer alternative to several other chemical coagulants. for instance, aluminium sulphate has been widely used

characterization and coagulation of a polyaluminum chloride,the 27 al–nmr spectra of the al2(so4)3, alcl 3, pac and pac–al 13 samples are shown in fig. 1.three signals can be observed for pac–al 13 and pac: the signal near 0.0 ppm represents the monomeric and dimeric aluminum species; the signal at 62.5 ppm denotes the al 13 species; and the signal at 80.0 ppm indicates the formation of al (oh) 4 − (the internal standard)(akitt and farthing

high-poly-aluminum chloride sulfate coagulants and their

the al c with high degree of polymerization may play a better bridge-aggregation, precipitation, and sweep-flocculation role in the coagulation process. wang et al. 20 found that when the charge neutralization ability of inorganic polymer coagulant reached a certain level, polymerization degree of the inorganic polymer coagulant would be the decisive factor affecting the coagulation efficiency.

polyaluminium chloride dosing effects on coagulation,different varieties have been synthesized, including polyaluminium chloride (pac), aluminium chlorohydrate (ach) and polyaluminium sulphate (pas) (pernitsky amp edzwald 2006). their individual performances are influenced by the raw water characteristics and the operating conditions for example, coagulant dosage, mixing speed, mixing time

polyaluminium chloride dosing effects on coagulation

in coagulation, these particles and any pathogens attached to them are removed, enhancing the water’s quality (miller et al. 2008). coagulation efficiency is greatly influenced by factors such as the type of coagulant and dose used, mixing speed and duration, operating ph, temperature, ionic strength, nature and concentration of organic matter

instead alum use poly aluminium chloride coagulant in water,pac=pacl. note: a) .the cost of poly aluminium chloride is twice/thrice of alum ( roughly the cost of pac-$0.4/ kg) b).one possible disadvantage in using poly aluminum chloride (pac) relates to the removal of dissolved organic carbon (doc) from water. it is well documented that effective doc removal is possible with alum,particularly when
