“…Almost complete color removal (98%) of biologically treated distillery effluent has been reported with conventional coagulants such as ferrous sulfate, ferric sulfate and alum under alkaline conditions (Pandey et al, 2003). The best results were obtained using Percol 47, a commercial organic anionic polyelectrolyte, in combination with ferrous sulfate and lime.…”

“…Vymazal (2014) concluded that the phosphate concentration in olive oil mill wastewater was higher than 410 mg/L. Meanwhile, it is reported that the temperature of industrial wastewaters varied greatly, which even reached 70-80°C (Pandey et al 2003). In order to investigate the potential of granular Aan-RM for treating industrial wastewater with high phosphate concentration in a wide temperature range, the initial phosphate concentration and adsorption temperature were chosen as 500 mg/L and 20-70°C, respectively.…”

Powdered-acid-activated-neutralized red mud (Aan-RM), the chemico-physically modified product of red mud, was for the first time employed with hydroxypropyl methylcellulose and powdered straw as the main ingredients for granular Aan-RM production for phosphate removal. In order to better understand the phosphate adsorption characteristics of granular Aan-RM, the influence of operational parameters on the performance of granular Aan-RM and the possible adsorption mechanisms involved were investigated. The results demonstrated that the adsorbent dosage, adsorption temperature, and initial solution pH influenced the adsorption performance of granular Aan-RM significantly. The maximum phosphate adsorption capacity of granular Aan-RM reached 153.227 mg/g with the granular Aan-RM dosage of 3.0 g/L, adsorption temperature of 40°C, and initial solution pH of 6.0. The whole adsorption process was well described by nth-order kinetic model and Langmuir-Freundlich isotherm. Meanwhile, X-ray photoelectron spectroscopy (XPS) analysis of P 2p peak on granular Aan-RM after phosphate adsorption demonstrated that 79.01 % of the phosphate was adsorbed through precipitation and ion exchange mechanisms with strong chemical bonds, and 20.99 % of the phosphate was adsorbed through surface deposition mechanism with weak chemical bonds.

“…Further treatment by oxidation technologies is generally effective on the colour but not COD [4,5], filtration processes are prone to fouling [6], and reverse osmosis generates a high salinity retentate that presents disposal difficulties [7]. Chemical coagulation removes colour and COD relatively effectively, but has a number of drawbacks [8]. The advantages of EC compared to conventional chemical coagulation include reduced wastewater acidification and salinity, superior coagulant dispersion and intrinsic electroflotation separation capability [9].…”

Electrocoagulation of fermentation wastewater by low carbon steel (Fe) and 5005 aluminium (Al) electrodes

et al. 2010

Successful application of electrocoagulation technology requires a thorough evaluation of electrode behaviour. This study is concerned with the treatment of fermentation wastewater, generated by molasses-fed biorefineries in large volumes and containing high concentrations of biorecalcitrant, coloured organic melanoidins that form a highly dispersed colloid. The polarisation behaviour, surface morphology and current efficiency of both hot rolled coil steel and 5005 aluminium electrodes were investigated. The steel electrodes were found to be susceptible to aggressive anodic pitting which is attributed to the high chloride content of the wastewater, while the aluminium exhibited anomalous corrosion of the anode and cathode. The redox potential of the wastewater has a significant effect on Fe 2? /Fe 3? speciation with steel electrodes and thus on the decolourising efficiency of electrocoagulation. The practical implications of the corrosion characteristics are discussed.
