“…The process depends on the dissolution of the sacrificial anodes to release the active coagulant precursors into the solution while electrolysis takes place on the cathode, where flotation plays a major role in pollutant removal. Reactions at the anode/cathode surface in an EC/EF process can be summarized as follows (Akarsu et al 2021):…”

Wastewater treatment plants (WWTPs) are one of the major vectors of microplastics (MPs) pollution for the recipient water bodies. Therefore, the recovery of MPs from WWTPs is extremely important for decreasing their accumulation and impact in aquatic systems. In this present study, the electrocoagulation-electroflotation (EC/EF) and membrane filtration processes were investigated in removing MPs from wastewaters. The effectiveness of different electrode combinations (Fe-Al and Al-Fe), current density (10–20 A/m2), pH (4.0–10.0) and operating times (0–120 min) on the removal of two different polymer particles in water were investigated to obtain maximum treatment efficiency. The effect of pressure (1–3 bar) on membrane filtration removal efficiency was also investigated. The maximum removal efficiencies were obtained as 100% for both polymer types with electrode combination of Al-Fe, initial pH of 7, current density of 20 A/m2 and reaction time of 10 min. The membrane filtration method also displayed a 100% removal efficiency. In addition, these laboratory-scale results were compared with the one-year average data of a plant treating with real-scale membranes. The results indicated that the proposed processes were supplied maximum removal efficiency (100%) compared to conventional secondary and tertiary treatment methods (2–81.6%) in the removal of microplastics.

“…The detergents and disinfectants used for sanitization and cleaning purposes add to the complexity, representing about 18-20% of the total wastewater generated (Bustillo-Lecompte & Mehrvar 2017; Terán Hilares et al 2021). The composition generally depends on various factors such as the size of the slaughterhouse, the type of bird slaughtered, the processing loads and the method of operation used (Yaakob et al 2018;Aziz et al 2019;Akarsu et al 2021). The variability of the diverse composition of PSW characteristics can be seen in Table 3.…”

Poultry slaughterhouses are generally large consumers of fresh water, which is exhausted as wastewater characterized by a high concentration of biological oxygen demand (BOD), chemical oxygen demand COD, and fats, oil, and grease (FOG). Cost-effective methods are required for the treatment of poultry slaughterhouse wastewater, with the aim of attaining a high quality effluent that can be reused in industrial processes to promote sustainability. As compared to conventional treatment methods, electrocoagulation is an efficient and low-cost system. Electrocoagulation is environmentally friendly, treating wastewater without the need of chemicals, thus limiting secondary pollution. The metal anodes initiate electrochemical reactions for coagulation and flocculation. Its distinct advantages include compact installation and simple operation. This paper offers a comprehensive review of recent literature that has been dedicated to utilizing electrocoagulation for poultry slaughterhouse wastewater treatment. This paper also examines aspects such as theory, potential applications, current applications, as well as economical assessment of the technique.

“…The optimization of the composite was done through face centered central composite (Gurukarthik Babu et al 2021). A study was conducted on the treatment of slaughterhouse wastewater using electrocoagulation and electro-flotation and the importance of electrode optimization (Akarsu et al 2021). Through a pyrolysis process the styrene is recovered from Waste Polystyrene (WPS) with the temperature of 470-505℃, heating rate of 40℃/ min and a carrier gas flow rate range of 115-140 ml/min, recovered the styrene with 64.52% (Mo et al 2014).…”

Bifacial photovoltaics (PV) is gaining rapid attention and their ability to generate more electricity is accelerating their deployment globally. However, literature on optimal bifacial PV is presented for the installation parameters of the system. In this study, we use response surface methodology (RSM) to investigate the flex and roadside reflector wastes as alternate reflectors for bifacial solar PV panels by using a statistical model. Our primary objective in this study is to examine the significant influence of key input factors (front irradiation, rear irradiation, temperature, thickness, and height) on the irradiance factor, total solar reflectance, and power extracted. The results show that the power extraction of the bifacial PV module using the waste flex material is 9%, higher than that of the road side sticker waste. The result indicates that among all other input factors, front irradiation is the most significant parameter.
