“…Applying stricter environmental laws which insist on the need to employ water/wastewater purification technologies to reduce the hazardous pollutants is required. In developing countries, water reclaiming in industries can play a significant role in conserving freshwater reserves [5][6][7][8]. The polluting and hazardous compounds such as phenol and linear alkylbenzene sulphonate (LAS) are present in carwash wastewater and can cause health hazards for human beings due to their poor biodegradability, high toxicity, and ecological aspects [9,10].…”

This work investigates the feasibility of the coupled electrochemical (electrocoagulation/flotation) and physical processes such as sedimentation, sand filtration, and activated carbon for treatment of automotive service wastewater (ASWW). The impacts of critical parameters viz. pH solution (5-9), reaction time (30-90) and current intensity (1-2) on linear alkylbenzene sulphonate (LAS) and phenol removal efficiencies as well as energy consumption and operating cost are studied. Central composite design (CCD) as a response surface methodology (RSM) is employed. The results reveal by increasing current intensity at low levels of pH, the phenol removal efficiency was increased significantly up to 95%. On the other hand, at pH 9.5 with current intensity of 1.5A, the highest removal efficiency of LAS was achieved with 98.5%. Moreover, at the optimum conditions, LAS and phenol removal efficiencies, energy consumption and operating cost are obtained 96.7%, 87.65%, 15.99 Wh, 0.001 US$, respectively. This process reveals a feasible technology for phenol and LAS removal from ASWW.
