The electrocoagulation (EC) treatment of Acid Blue 113 (AB 113) was performed on the basis of chemical oxygen demand (COD) removal efficiency using an iron anode. The process variables, including current density (1-5 A/dm 2 ), pH (5.5-7.5), and supporting electrolyte concentration (1-3 g/L) were investigated. Under the optimum operating conditions, more than 91% COD removal efficiency was found. The optimum conditions were obtained with 3 A/dm 2 of current density, pH 6.5, and 2 g/L of supporting electrolyte concentration. COD removal rates obtained during the EC process can be described using a pseudo-kinetic model. The experimental kinetic data fit well with pseudo first-order kinetic model, with no significant change on the rate constant after 3 A/dm 2 of current density. The absorption spectra and Fourier transform infra red analysis were also performed to characterize the mechanism and nature of dye cleavage.

“…Various techniques of treating wastewater contaminated with BGD such as electrocoagulation (Alinsafi et al., ; Kuokkanen, Kuokkanen, Rämö, & Lassi, ; Singh, Srivastava, Tripathi, & Dutt, ), membrane separation (Shirmardi, Mesdaghinia, Mahvi, Nasseri, & Nabizadeh, ), adsorption (Al‐Jlil, ; Ansari & Dezhampanah, ; Arivoli, Hema, Karuppaiah, & Saravanan, ; Balarak & Mahdavi ; Idan, Abdullah, Choong, & Jamil, ; Segun Esan, Nurudeen Abiola, Owoyomi, Olumuyiwa Aboluwoye, & Olubunmi Osundiya, ), chemical coagulation (Chithra, Thilakavathi, Murugan, Marimuthu, & Balasubramanian, ), and biological methods (Dutta, Ghosh, Moi, & Saha, ) have earlier been presented. However, the adsorption process is considered the most superior technique in treating water and wastewater contaminated with BGD (Daneshvar et al., ).…”

The optimum preparation conditions for composite snail shell‐rice husk (SS‐RH) adsorbent that gives the optimum brilliant green dye (BGD) uptake has been found at a calcination temperature of 681.10°C, a calcination time of 2.61 hours, and a mixing ratio of 2.61 snail shell‐rice husk, leading to a 97.78% BGD uptake using Central Composite Design. The SS‐RH adsorbent characterization was executed before and after adsorption using a scanning electron microscope (SEM), energy‐dispersive x‐ray spectroscopy (EDS), and Fourier‐transform infrared spectroscopy (FTIR). The SEM image before adsorption showed a highly porous, uniform matrix formation with wide cavities resulting from favorable preparation by calcination at optimum conditions, whereas the image revealed complete adsorption of the BGD onto the vacant pores of the calcined SS‐RH after adsorption. EDS analysis revealed formation of active metal oxides on the surface of the composite SS‐RH was enhanced by the calcination process before adsorption, while changes in their weight percent were noticed after adsorption, showing the influence of the active metal oxides on the process. FTIR revealed the existence of functional groups on the SS‐RH surface, which can interact with the BGD molecules to enhance effective adsorption and cause a shift in the values of the wavenumbers of broad peaks before and after adsorption, respectively. In conclusion, the results obtained have proven SS‐RH to be a valuable composite adsorbent for BGD adsorption.

The greater demand for potable water, both locally and worldwide, has directed a huge interest amongst researchers to investigate the possibility of recycling and reusing wastewater from laundry run-offs. The advantage of using recycling wastewater from such sources is mainly due to the fact that these bulk volumes of wastewater are considered to be less chemically polluted in comparison to those discarded from industrial effluents and wastewater sources. Almost all laundry detergents contain surfactants, whose main function serves to remove dirt/soil from contaminated items. Thus, an analysis of the surfactant levels before and after a treatment process is important to confirm that the surfactant has in fact carried out its intended purpose. Electrocoagulative treatment of wastewater, a well-researched and well-documented clean-up process that involves the production of aluminium hydroxy species by oxidation of aluminium metal upon the application of a controlled voltage which adsorbs fine particulate matter and pollutants from the wastewater has been investigated as a clean-up application to the treatment of laundry wastewater. The use of a biological treatment process which entails treating the wastewater with aerobic bacterial specie specifically designed to degrade fats, lipids, protein, detergents and hydrocarbons has also been investigated.
