Treatment of wastewater effluents from paper-recycling plants by coagulation process and optimization of treatment conditions with response

In the present study, a coagulation process was used to treat paper-recycling wastewater with alum coupled with poly aluminum chloride (PACl) as coagulants. The effect of each four factors, viz. the dosages of alum and PACl, pH and chemical oxygen demand (COD), on the treatment efficiency was investigated. The influence of these four parameters was described using response surface methodology

Characterization and coagulation of a polyaluminum chloride (PAC) coagulant with high Al13 content

The 27 Al¨CNMR spectra of the Al 2 (SO 4) 3, AlCl 3, PAC and PAC¨CAl 13 samples are shown in Fig. 1.Three signals can be observed for PAC¨CAl 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 ?

Study of production 500 kg/batch polyaluminum chloride from aluminum hydrate - IOPscience

A pilot-scale experiment with a capacity of 500 kg/batch feed was conducted by reacting Al (OH) 3 with HCl and H 2 SO 4, then neutralized using CaCO 3 to obtain liquid PAC and gypsum as a by-product. The variation of acid concentration as reactant and reaction time were conducted to determine its effect on the composition of PAC and the amount

poly-aluminium chloride (pac)

Poly-Aluminium Chloride (PAC)

Accepta¡¯s poly-aluminium chloride (PAC) is a highly efficient coagulant with low generation of waste sludge in a wide pH range, even at low temperatures. Accepta PAC is used for several applications including the treatment of drinking water, swimming pool water, wastewater treatment, the treatment of sewage and industrial effluents.
