“…Saleem et al (2011) found the allowable limits of BOD in the wastewater at 24.7 mA/cm2 current density. Idusuyi et al (2022) noted that optimum COD and BOD removal efficacy of 90.7% and 97.67% were found at 10 V. Data showed that the greatest removal of TSS was received by <3 for SBC, 1 SRG, 80 for SCC, 1 for PMTF and 1 mg/L for SMH at 21 volt as compared with 89,46,1760,38 and 54 mg/L at 0 volt, respectively. It was observed that the highest removal of turbidity (NTU) was observed up to <1 for SBC, 5 SRG, 55 for SCC, <1 for PMTF and 2 NTU for SMH at 21 volt as compared to 106, 148, 830, 23 and 58 NTU at 0 volt, respectively (Fig.…”

The reuse of treated domestic wastewater is an imperative source of water for numerous purposes. The treatment of municipal wastewater can be process by utilizing the technique for electrocoagulation. Electrocoagulation (EC) is an eco-friendly technique that combines the functions and advantages of conventional coagulation, flotation, and electrochemistry in water and wastewater treatment. The aim of present study was to assess the potential of electrocoagulation process in removing COD, BOD, TSS, turbidity, sulphate, nitrate, chloride and TDS from municipal wastewater. This experimental study was carried out at a batch system by using copper and aluminium electrodes aiming to treat the municipal wastewater at (0, 7, 14, and 21 volts, 50mamp for 60minutes) from Sample Baloch Colony (SBC), Sample Rind Goth (SRG), Sample Cattle Colony (SCC), Sample Pakistan Machine Tool Factory (SPMTF) and Sample Mehran Highway (SMH). The results revealed that the maximum removal efficiency of COD 96% for SPMTF, BOD 38.5% for SPMTF, TSS 98.14% for SMH, Turbidity 95.7% for SPMTF, Sulphate 95.9% for SRG, Nitrate 95.23% for SMH, Chloride 97.92% for SMH and TDS 96.9% for SRG at 21 volt. The present study suggested that the treated wastewater could be safely reuse for lawns, parks, tree plantation and recreation purpose.

“…Other techniques show metal treatment efficiency such as membrane technology [42]. The benefits of using electrocoagulation method are low costs [43], little energy [44] and the possibility of eliminating a wide range of pollutants [45]. Biological treatment, fenton oxidation, membrane separation and physiochemical treatment have some major disadvantages, such as their high operational costs, higher sludge formation, long retention time and production of toxic byproducts [46][47][48].…”

Pollution with contaminants from effluents of industrial units constitutes a danger to health and environment. This is the case of chromium (Cr) and formaldehyde [CH 2 O (H−CHO)] contained in leather tannery effluents, identified and characterized by ICP-OES (Inductively coupled plasma -optical emission spectrometry) and HPLC (High Performance Liquid Chromatography). The levels recorded for these two contaminants in wastewater constitute an environmental risk of average degree. The treatment of this wastewater by electrocoagulation completely eliminates chromium and reduces organic pollution by 65%. We applied an electric current (I) of variable intensity (1 to 2.5 Ampere). The best results were obtained with the highest current intensity.

“…The success of electrocoagulation is already known for treating wastewater, such as recycling water contaminated by domestic sewage [38]. The advantages of this method The success of electrocoagulation is already known for treating wastewater, such as recycling water contaminated by domestic sewage [38]. The advantages of this method over others that use an electric current to coagulate suspended solids in contaminated water are a reduction in energy consumption and a reduction in operating costs [36,38,42].…”

Triturated Moringa oleifera seeds have components that adsorb recalcitrant indigo carmine dye. Coagulating proteins known as lectins (carbohydrate-binding proteins) have already been purified from the powder of these seeds, in milligram amounts. The coagulant lectin from M. oleifera seeds (cMoL) was characterized by potentiometry and scanning electron microscopy (SEM) using MOFs, or metal–organic frameworks, of [Cu3(BTC)2(H2O)3]n to immobilize cMoL and construct biosensors. The potentiometric biosensor revealed an increase in the electrochemical potential resulting from the Pt/MOF/cMoL interaction with different concentrations of galactose in the electrolytic medium. The developed aluminum batteries constructed with recycled cans degraded an indigo carmine dye solution; the oxide reduction reactions of the batteries generated Al(OH)3, promoting dye electrocoagulation. Biosensors were used to investigate cMoL interactions with a specific galactose concentration and monitored residual dye. SEM revealed the components of the electrode assembly steps. Cyclic voltammetry showed differentiated redox peaks related to dye residue quantification by cMoL. Electrochemical systems were used to evaluate cMoL interactions with galactose ligands and efficiently degraded dye. Biosensors could be used for lectin characterization and monitoring dye residues in environmental effluents of the textile industry.
