“…It has been reported 38 that the cost of operation accounting for electrical power consumed, chemicals, and consumption of electrodes, during electrocoagulation of agro-industry wastewater ranges from US $0.95/m 3 to US $4.93/m 3 . Bayramoglu et al concluded that, in the case of the Fe electrode, the operating cost is approximately US $0.1/(kg COD removed), and for the Al electrode, it is US $0.3/(kg COD removed).…”

The technical and economic feasibility of various electrochemical processes as pretreatment step for biological treatment for the management of kraft bagasse pulp bleach effluent has been studied, and the results are compared with that of the conventional chemical coagulation followed by biological treatment. A modeling methodology for integrating processes involving electrochemical and biological methods is proposed. Optimal combinations of operating variables giving a definite completion of pollutant removal are derived from the empirical models of each process. However, both the electrochemical steps as electrocoagulation and electro-oxidation were observed to perform technically better, and the former was noticeably more attractive based on the overall operating cost. The cost of electrocoagulation–biological (EC-Bio) treatment giving 80% COD removal was determined to be US $0.166/m3. A 41% reduction in the treatment cost was achieved when the conventional chemical coagulation–biological (CC-Bio) methodology replaced by an EC-Bio system. The research revealed the feasibility of electrochemical steps as a primer in the reduction of organic load and improvement in the biodegradability of pulp-bleaching effluent.

“…literature there is only the work ofDrogui et al 2009 that measured the removal of BOD in oily ship effluents (oily wastewater) through EC using Al electrodes in BP configuration. They found that at a current of 0.3 A and a treatment time of 60 minutes (optimum conditions) 89.4 % of the 30 BOD was removed.…”

“…This work achieved a BOD removal of 82.1 % at optimum conditions which is compatible with the work ofDrogui et al 2009. 6.1.5 Removal of TSS There were two works found in literature(Sardari 2018, Drogui et al 2009) who measured the TSS removal from oily wastewater after EC treatment in bipolar configuration. Sardari 2018 treated produced water using Aluminium electrodes and at a current of 3 A and a treatment time of 30 seconds and achieved a TSS removal of 91 % Drogui et al 2009.…”

The aim of this paper is to investigate whether simulated Jordan refinery wastewater can be treated through electrocoagulation (EC) to conform to the most stringent Jordanian norms for reusing this wastewater for irrigation of cut flowers and to perform cost analysis for a treatment plant whose core are the EC reactors. The method used for estimating the fixed (capital) costs of the treatment plant is taken from literature and is based on a study estimate (factored estimate) that depends on the knowledge of major items of equipment. Most of the operating costs are estimated based on percentages which are also taken from literature. The best percentage removal of COD, BOD, TSS, fat, oil& grease (FOG), bicarbonate (HCO3 − ), and phenol from simulated Jordan refinery wastewater so that
