polyaluminium chloride dosing effects on coagulation performance: case

Polyaluminium chloride dosing effects on coagulation performance: case

The effects on the treatment process of three different sets of mixing speed pairs ¨C 180/40, 180/25 and 150/25 revolutions per minute (fast/slow) ¨C in a pH range of 6.5 to 8.0 were investigated. The mixing speed and PAC dose yielding the best coagulation were 150/25 rpm and 15 mg/L respectively.

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

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

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.

Water | Free Full-Text | Application of Polyaluminium Chloride

Polyaluminium chloride (PAC) has been widely used as a chemical coagulant in water treatment. However, little is known about the impact of PAC performance on the microbial community in sediments. In this study, the archaeal, bacterial, and fungal communities in urban river sediments with and without PAC treatment were investigated. Prokaryotic diversity decreased at the PAC addition site (A2

Cationic Starch and Polyaluminum Chloride as Coagulants

Currently, water is being treated by water treatment plants that use aluminum- or iron-based salts and synthetic polymers for coagulation. However, these synthetic coagulants have flaws, including the production of large amounts of chemical sludge, considerable effects on the pH of the purified water, relatively expensive to use, and potentially toxic effects on the environment.
