“…There is certainly no "ideal reactor" of the EC in use. Operations conditions follow a large variation between projects, with adjustments for specific applications (BASSALA et al, 2017). Each electrolytic system has its own set of advantages and disadvantages, including varying degrees of treatment and skill; however, important in a design of an electrocoagulation reactor is to get the maximum efficiency of the equipment is achieved (DÍAZ et al, 2014).…”

“…Effluents of industrial processes are constituted of high organic charge. Effective removal of its components it is of vital importance on the controlling of increasing pollution of receives water, because the excessive nutrients, especially nitrogen and phosphorus, can cause eutrophication and ecologic imbalance in the ecosystem (BASSALA et al, 2017).…”

This study investigated the use of iron and aluminum and their combinations as electrodes to determine the technically sound and economically feasible electrochemical approach for the treatment of anaerobic digestion effluent. The results indicated that the use of iron as anode and cathode is the most suitable solution among different electrode combinations. The reduction of turbidity, total chemical oxygen demand, total phosphorus, total coliforms, Escherichia coli, Enterococci, and phages in the reclaimed water were 99%, 91%, 100%, 1.5 log, 1.7 log, 1.0 log, and 2.0 log, respectively. The economic assessment further concluded that the average treatment cost is $3 per 1000 L for a small-scale operation handling 3000 L wastewater/day. This study demonstrated that the electrocoagulation (EC) is a promising technique for the recovery and reclamation of water from anaerobic digestion effluent. Even though its energy consumption is higher and the nitrogen removal is insufficient compared to some conventional wastewater treatment technologies, there are several advantages of the EC treatment, such as short retention time, small footprint, no mixing, and gradual addition of coagulants. These features make EC technology applicable to be used alone or combined with other technologies for a wide range of wastewater treatment applications.

“…Biological processes such as aerobic and anaerobic, physicochemical processes such as electrocoagulation, membrane process and adsorption are widely used to treat the dairy effluent due to the presence of rich in organic matter [9,10]. However, the above-mentioned treatment processes produce maximum amount of sludge, periodical maintenance, hydraulic/solid retention time, requirement of pretreatment, cost of electrodes/coagulants/adsorbents, recovery of coagulants/adsorbents, difficulties faced in disposal of sludge, cost of electricity and membrane, periodical replacement of electrode/membrane and toxicity of effluent leads to limitation of the process [11][12][13][14]. Although these methods produce considerable results in pollutant removal, its not give complete elimination of pollution load in dairy effluents.…”

The present study focused on the various advanced oxidation processes; Ozone, UV radiation, O 3 /H 2 O 2 , O 3 /UV, UV/H 2 O 2 and O 3 /UV/H 2 O 2 for treatability of dairy industry wastewater. With this aim, the trials were carried out in cylindrical reactor fortified with UV radiation and Ozone injection. Efficiency of the treatment process was evaluated considering Chemical Oxygen Demand (COD), lactose reduction and process parameters were determined to be reaction time, pH, circulation rate, and H 2 O 2 dosage. 32.5%, 35.2% , 25%, 83% COD and 40.6%, 43.6%, 38.2%, 80% lactose reduction efficiency were obtained under the operating conditions for O 3 /H 2 O 2 , O 3 /UV, UV/H 2 O 2 and O 3 /UV/H 2 O 2 processes, respectively. As per this outcome, UV/H 2 O 2 /O 3 process gave more than 65% of COD and 52.36% of lactose reduction efficiency than other hybrid processes. Optimum conditions for UV/H 2 O 2 /O 3 process (pH = 5, time = 180 mins, circulation rate = 50 mL/h and H 2 O 2 dosage of 0.5 mL) resulted in 88% of COD and 93.4% lactose reduction.
