Abstract

Abstract This research reviews nano zero valent metal oxidation coupled with ozone for degradation of wastewater effluent. The technology in wastewater treatment is gradually innovating. Car wash wastewater constitutes and promotes water and environmental pollution. In wastewater treatment, a variety of methods are available for treatment of wastewater. The chosen method should be cost effective and easy to operate. In the treatment of car wash wastewater, certain parameters are investigated such as pH, time, dosage of treating agent, presence of hydrogen peroxide, and competing cations. The characteristics of treated and untreated car wash wastewater are usually analysed, produced catalyst morphology and elements maybe observed and compared using the XRD, FTIR, SEM + EDx, and BET. A combined treatment of different phases is reported to remove total suspended solid (TSS), inorganic materials such as sodium chlorides (NACL), heavy metals such as lead, oil and grease, as well as phosphates and nitrates. This review will discuss on the treatment methods being practised in wastewater engineering field, chosen treatment methods after review with supports, and combination concerns on the chosen treatment methods along with consequences to the environment and human health.
