Can polyaluminum chloride treat textile dyeing effluents?

The study aimed to assess the coagulant efficiency of polyaluminum chloride (PAC) for treating textile dyeing effluents. The discharged textile dyeing effluents, when untreated, severely pollute water and soils, posing a threat to the entire environment.

Could PAC be a coagulant for textile dyeing effluents?

Textile and dyeing factories play an incredibly imperative role in deteriorating the water quality by releasing their effluents in ponds, rivers, lakes, and oceans. PAC (Polyaluminum Chloride) could be a potential coagulant for treating the textile dyeing effluents, helping to build a sustainable environment.

Is polyaluminium chloride a safe coagulant?

Polyaluminium Chloride is a safer alternative to several other chemical coagulants. For instance, aluminium sulphate has been widely used as coagulant for many years. It removes contaminates and general turbidity from water during the water treatment process.

Does recycled alum sludge remove dye from textile dye wastewater?

Dye removal from textile dye wastewater using recycled alum sludge. Water Research, 35(13), 3147-3152. Kacha, S.; Derriche, Z.; and Elmaleh. S. (2003). Equilibrium and kinetics of colour removal from dye solutions with bentonite and polyaluminium hydroxide. Water Environment Research, 75(1), 15-20.

Why is polyaluminium chloride important during water treatment process?

Polyaluminium chloride has several features important during water treatment process, and the features are outlined in the following list:- PAC helps speeding up the process of flocs formation, and the settling of the flocs at the bottom. The process makes flocs that are formed easier to be filtered out.

Does PAC coagulant remove TDs & cod from textile dyeing effluent?

The total suspended solids (TSS) of various textile dyeing effluent samples were found to be in the range of 401–233 mg/L, which is significantly higher than the permissible limit of TSS (150 mg/L) as per DoE and EPA standards. The passage does not directly mention the removal of TDS and COD by PAC coagulant, but it is commonly used for such purposes in textile effluent treatment. Therefore, the passage implies that PAC coagulant likely removes TDS and COD as well.
