“…Shock load of CCDB was highly alkaline (pH 13) and contains very hazardous chemicals, while wastewater from CCPB was very acidic (pH 1.03) and contains high concentrations of iron (2300 mg/L) and zinc (2400 mg/L). These results are in agreement with the results obtained by Abou-Elela et al, (2018). Also, results indicated that more contaminated wastewaters were generated from DBC, CCIB, and CCUF.…”

“…Characterization of wastewater from the three end-off-pipes (A, B, and C) during the normal daily operation indicated that the quality of discharged wastewater meets the National Regulatory Standards for wastewater discharge into public sewerage network (MD44/2000). This is in agreement with the published works of many authors (Abou-Elela et al, 2018;Macko & Searight, 2008) who indicated that rinsing process is the primary source of wastewater generated during normal daily operation and it is often containing low concentrations of process chemicals (Table 1).…”

“…Environmental, economic, and social limitations increasingly posed by conventional wastewater systems, new approaches that incorporate controlled release of effluent is designed with sustainability in contrast to energy-intensive and chemical-dependent systems (Almeida et al, 2018). In a study by Abou-Elela et al, (2018), they achieved a sustainable and cost-effective solution to shock loads generated from water heater industry by applying the control release approach.…”

The aim of this study is to find out a sustainable and cost-effective solution to manage hazardous shock loads from metal finishing and electro-coating industry. Results indicated that the main sources of hazardous wastewater are coming from batch chemical cleaning of degreasing basin (CCDB) (pH 13) and contains very hazardous chemicals, batch chemical cleaning of phosphating basin (CCPB) (pH 1.03) and contains high concentrations of iron (2300 mg/L) and zinc (2400 mg/L) and degreasing basin contents (DBC). Different treatment approaches were investigated. Results indicated that mixing CCDB with CCPB at their actual discharge allowed to form a self-coagulant of metal hydroxide which was utilized to treat the (DBC) followed by sedimentation. Removal efficiency of COD (87%), TSS (94%), and oil and grease (92%) were achieved. To compare the efficiency of this treatment approach, conventional chemical coagulation of DBC was carried out using FeCl 3 but the amount was very high. In conclusion, results proved the advantage of using self-coagulation to treat DBC since it eliminates the use of external chemicals and provides an integrated solution for the three main sources of hazardous pollutants. © 2021 Water Environment Federation • Practitioner points• The manuscript provide an innovative and sustainable solution to the shock loads of hazardous wastewater generated from metal finishing and E-coating industry by utilizing iron-rich wastewater from chemical cleaning of phosphating basin and alkaline wastewater from chemical cleaning of degreasing basin to produce metal hydroxide. • The metal hydroxide was cost-effective and technically effectively than external coagulant in treating highly polluted degreasing basin content at due discharge time. • Iron-rich wastewater could be used to produce self-coagulant of iron hydroxide.• Mixing iron rich wastewater and alkaline wastewater produce iron hydroxide.• Iron hydroxide is cost-effective in treating hazardous wastewater of degreasing basin.

“…Phenol is classified by the US EPA as one of the most challenging classes of pollutants requiring urgent removal from waste streams. The standard of phenol limits for wastewater discharge is 0.005 mg/L for surface waters and 0.05 mg/L for the sewerage system (Abou‐Elela et al ., 2018). Some techniques have been used to eliminate the phenol from aqueous solutions such as adsorption, biological treatment, chemical oxidation, distillation, precipitation, ion exchange, solvent extraction, reverse osmosis, membrane processes and electrochemical methods (Rodrigues et al ., 2011; Ma et al ., 2013; Gaber et al ., 2017).…”

This work investigated the removal of phenol from petroleum wastewater by the electro‐oxidation process. The experimental design was developed on a pilot‐scale electro‐oxidation system equipped with a cylindrical shape of graphite electrodes as an anode and stainless‐steel electrodes as a cathode. An initial study was performed based on operating variables such as current density and time on real petroleum wastewater. The optimum conditions were obtained as a current density of 3 mA/cm2 and time 15 min. Under these applied optimum conditions, complete phenol removal from an initial concentration of about 6.8 mg/L was achieved. Also, 50–60% removal of organic matter in terms of chemical oxygen demand (COD) and biological oxygen demand (BOD). The removal of organic matter using electro‐oxidation requires a long reaction time. Also, the economic study indicated that the energy consumption was determined to be 0.79 kWh/m3 and the operating cost was 0.051 $/m3 which is very economical compared with conventional methods.

“…To meet this challenge, it is important to find alternative solutions for wastewater treatment using innovative and developed technologies (Abou-Elela et al, 2019b). New technologies typically follow a development process that leads from laboratory and bench scale investigations to pilot studies and to initiate use or "full-scale demonstrations" as well (Abou-Elela et al, 2018). Biofilm-based passive aeration systems are one of the wastewater treatment systems that have attracted recent attention as an alternative energy efficient and low maintenance technologies for the treatment of municipal wastewater (Clifford…”

Water-energy issues are of growing importance in the context of water shortages, higher energy, material costs, and climatic change.Wastewater from industry and domestic use should meet a specific set of requirements before being returned to the natural environment (Abou-Taleb et al., 2020). In all countries, regardless of the income levels, appropriate management of these wastewaters is a costly and persistent challenge (Wallace et al., 2015). To meet this challenge, it is important to find alternative solutions for wastewater treatment using innovative and developed technologies (Abou-Elela et al., 2019b). New technologies typically follow a development process that leads from laboratory and bench scale investigations to pilot studies and to initiate use or "full-scale demonstrations" as well (Abou-Elela et al., 2018).
