“…As a result, it causes the solubility of aluminium to increase gradually (Su et al, 2010). However, when the temperature is too high, the water vapour inside the container is released, and the concentration of the solution rises (Zhang et al, 2019), which leads to the breakage of chemical bonds (Jiang & Zhu, 2021;Zhang & Ren, 2013). As a result, it causes large amounts of sulphate ions to form a new molecular layer structure, and the solubility of aluminium is reduced (Zhang et al, 2015b), thus inhibiting the extraction of alumina.…”

Polymerised aluminium ferric sulphate (PAFS) was prepared from aluminium dross as a coagulant in wastewater treatment. The effects of leaching time, leaching temperature, and sulfuric acid concentrations on the turbidity removal of the wastewater were investigated, and the optimum conditions were determined using response surface methodology. The results showed that the optimum PAFS preparation conditions were at a leaching time of 60 minutes, a leaching temperature of 65°C, and a sulfuric acid concentration of 1 mol/L. Furthermore, experiments were performed to investigate the effect of coagulant dosages using the PAFS prepared under the optimum leaching conditions, settling time and initial pH of the wastewater on the turbidity removal efficiency. As a result, it was found that the optimum coagulation conditions for PAFS coagulants were at a settling time of 15 minutes, coagulant dosage of 0.5g, and raw water pH 8. Under these optimum conditions, the turbidity removal efficiency of the wastewater was 91.45%. The purpose of this study was to investigate the possibility of aluminium dross utilisation as a coagulant agent for wastewater treatment. Therefore, it can be concluded that PAFS prepared by leaching metal oxides from aluminium dross is an effective wastewater coagulant.

“…Moreover, dimethyl phthalate ester are difficult to degrade biologically and photo-chemically. Dimethyl phthalate ester, negatively charged particles, is considered to easily remove from water through Coagulation-flocculation process 11 . Coagulationflocculation process is an important water pollution control technology that finds a wide range of application in water or wastewater treatment facilities 12,13 .…”

Flocculation process with P(AM-DAC-DMC) as a novel flocculant was used for the removal of dimethyl phthalate from water. The structures and morphologies of P(AM-DAC-DMC) was characterized by nuclear magnetic resonance spectra ( 1 H NMR) and scanning electron microscope. In order to maximize the removal efficiency of dimethyl phthalate, single factor experiment was investigated with the factors of dosage, initial pH value, settling time and molecular weight. Furthermore, an orthogonal array L9 (3 3 ) were employed to optimize the factors of dosage, initial pH value and settling time. The results showed that the optimal conditions were dosage of 9.0 mg L -1 , initial pH value of 6.0 and settling time of 3 h. In addition, the removal rate of dimethyl phthalate reached a maximum value being 94.6 %.

“…Therefore, there is a need for improving the treatment efficiency during the coagulation-flocculation process to solve this problem. At present, drinking water treatment processes mainly consist of coagulation, sedimentation and gravity filtration and coagulation is an essential process for the removal of various particulates and organic matter [3][4][5] . The coagulation was applied widely in water and waste water treatment and flocculating effect is mainly determined by the qualities and species of flocculants [6][7][8] .Cationic polyacrylamide is the most frequently applied traditional organic coagulant in the world 9,10 .…”

The provision of high-quality drinking water is a fundamental element of good public health 1 . With the over-exploitation of groundwater, the surface water has become the main source of water supplies in China. However, as the development of petroleum industry, chemical industry and synthetic drugs industry, there was more and more organic pollution in surface water 2 . Serious soil erosion also increased turbidity of the water body. which is a serious threat to human health. Therefore, there is a need for improving the treatment efficiency during the coagulation-flocculation process to solve this problem. At present, drinking water treatment processes mainly consist of coagulation, sedimentation and gravity filtration and coagulation is an essential process for the removal of various particulates and organic matter [3][4][5] . The coagulation was applied widely in water and waste water treatment and flocculating effect is mainly determined by the qualities and species of flocculants [6][7][8] .Cationic polyacrylamide is the most frequently applied traditional organic coagulant in the world 9,10 . Recently, organic polymer flocculants have been developed rapidly and become applied widely, especially in China, Japan and the United State.
