Preparation and performance of a high purity poly-aluminum

The coagulation process consists of three sequential steps: coagulant formation, colloid/particle destabilisation, and particle aggregation. Coagulants used for water and wastewater treatment are predominantly inorganic salts of aluminium and iron.

Is polyaluminium chloride safe for treatment of potable water

Polyaluminum chlorides attach to impurities in the water and filtered out. Alum treated waters can contain higher levels of aluminum, turbidity and sulfate; polyaluminum chloride treated waters can contain higher levels of chloride and lower levels of aluminum and turbidity.

Polyaluminium chloride dosing effects on coagulation

The coagulation process in conventional water treatment could be enhanced and the ensuing water pH decline reduced appreciably by applying the right dosage of polyaluminium chloride and appropriate process conditions of pH, fluid mixing speed matrix and residence time.

USING POLYALUMINIUM COAGULANTS IN WATER TREATMENT

2.0 POLYALUMINIUM COAGULANTS. Recently, a number of alternative aluminium-based coagulants have been developed for water treatment applications. These compounds have the general formula (Aln(OH)mCl(3n-m))x and have a polymeric structure, totally soluble in water. The length of the polymerised chain, molecular weight and number of ionic charges

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 ¡­

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
