Coagulation/flocculation of dye-containing solutions using
In this research, the performance of Polyaluminium Chloride (PAC) and Polyaluminium Chloride sludge (PACS) as coagulants for acid red 119 (AR119) dye removal from aqueous solutions were compared.
Coagulation mechanisms with PACl were investigated by measuring the RT and ZP at various dosages at a constant final pH. Fig. 1 shows the effects of PACl dosages on the RT and ZP at different final pH values. With final pH values of 6.0, 7.0, and 8.0 [Fig. 1(a–c)] the typical four coagulation zones (i.e. stabilization, charge neutralization destabilization, restabilization and sweep) are
Coagulation/Flocculation Potential of Polyaluminium
您好，读者！ 请
Coagulation mechanisms of polyaluminum chloride (PACl) at various dosages were studied using a conventional jar test at different final and initial pH values during treating kaolin suspension. The optimal final pH and dosages for PACl were obtained based on residual turbidity and zeta potential of flocs.

Coagulation-flocculation is one of the most important and common chemical treatment methods adopted for NOM removal. Utilization of aluminum (Al)-salts as coagulants for NOM removal dates back centuries, however, there have been disputes regarding the potential adverse effects of Al on humans and organisms (Cheng and Chi, 2002).
The Performance of Polyaluminium Chloride
The Performance of Polyaluminium Chloride and Bentonite clay Coagulant in the Removal of Cationic and Anionic Dyes Coagulation-flocculation and adsorption methods are the most effective
The effect of polyaluminum chloride (PAC) dosage on the coagulation performance and the floc characteristic with respect to the treatment of surface water with low specific UV absorbance (SUVA) value was investigated in this paper. The subsequent effect on chlorine decay was studied by a first decay model and AQUASIM modeling software. The results showed that natural organic matter (NOM
Treatment of olive mill wastewater using a coagulation
The treatment of OMW by means of coagulation–flocculation using various inorganic materials (poly‐aluminum chloride – PAC, aluminum sulphate) and organic poly‐electrolytes (anionic polyacrylamide – Flocan 23–20, anionic polyelectrolyte – Praestol 2240) was investigated in this study.
A study was conducted to treat stabilized leachate by applying polyaluminium chloride (PAC) and tobacco leaf extract as a coagulant and coagulant aid. Experimental results indicated that the tobacco leaves were positively charged. The removal rate of the chemical oxygen demand, using 1500 mg/L PAC as a sole coagulant, was approximately 63% and increased to 91% when 1000 mg/L PAC was mixed

The efficiency of using polyaluminium chloride (PAC) as a coagulant in the coagulation-flocculation process to remove SS, colour, COD and ammoniacal nitrogen from semi-aerobic leachate as compared with alum and ferric chloride were also determined.
- Does pH affect the performance of polyaluminum chloride (PAC)?
- The performance of PAC was dependent on pH. The synthesized PΑC was efficient coagulant for water treatment. The present work was aimed to synthesis of polyaluminum chloride (PAC) using calcium oxide as a basification agent and optimization of process parameters on the yield of medium polymer species in PAC.
- Is polyaluminum chloride a good coagulant for water treatment?
- Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
- What is high-purity poly-aluminum chloride (PACL)?
- Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
- Is polyaluminium chloride better than polyelectrolyte – alum-based coagulation?
- At the Barekese Water Treatment Plant in Ghana, an alternative, the polyelectrolyte – polyaluminium chloride (PAC) is also used in coagulation but limited information is available on the operating conditions required to achieve better performance than alum-based coagulation.
