Synthesis of polyaluminium chloride/papermaking sludge
Synthesis of polyaluminium chloride/papermaking sludge-based organic polymer composites for removal of disperse yellow and reactive blue by flocculation Article in Chemosphere 231 · May 2025
In this study, a series of polyaluminium chloride/papermaking sludge-based organic polymer (PAC-PSBF) composites with different PAC basicity and PAC/PSBF mass ratios were prepared from papermaking sludge. The basic properties of the aforementioned composites were characterized, and their flocculation efficiencies were studied in the disperse yellow (DY) and reactive blue (RB)

Papermaking sludge, an industrial waste, is abundant in biomass (cellulose, hemicellulose and lignin) (Li et al., 2017). Lignin, extracted from papermaking sludge, could be modified and used as functional materials in wastewater treatment. Amor et al. (2015) prepared a sulfuric acid lignin-based flocculant, which performed well in dye removals.
Alternative cost-effective preparation method
The dosage of polyaluminium chloride (PAC) was varied in the following concentrations: 0, 75, 100, 125, 150 and 175 mg/L; as well as bubble rise velocity of 18 and 9 cm/min for two types of paper
The coagulation characteristic of PAFC was used to treat papermaking and dyeing wastewater, the optimum conditions such as dosage of PAFC, pH, agitating intensity and time were obtained. Results demonstrated that PAFC isn't superior to PAC and PFS in such flocculate characteristics as the dosage of PAFC and the ratio of deturbidity of wastewater, but its removal efficiency of COD, which
CN1266821A - Polyaluminium chloride and chitin compounded
A compound flocculant of natural organic and inorganic high-molecular substances is prepared from polyaluminium chloride and chitosan through proportioning, mixing, stirring and reaction. Its advantages are excellent electric neutralizing power, high-efficiency bridging action and no toxicity.
