With the increase in transportation demand and facilities this era significant improvement people’s living standards, annual production sales of vehicles are steadily increasing. this, issues car wash wastewater treatment water pollution becoming more serious. Car mainly comprises fine sand, slick oil, suspended solids (SS), surfactants, can be quantified as chemical oxygen (COD) on a normative...

This paper presents an evaluation of the suitability of a mixed absorbent based on peat and carbon-containing ash for treatment of wastewaters, such as wastewater from professional car washes, landfill leachate and stormwater. This mixture is very attractive, since it is a low-cost material which has a capability to simultaneously remove inorganic as well as organic pollutants. Since any filter...

Untreated motor vehicle waste has the potential to damage environment. The photodegradation method can decompose pollutants with help of UV-A light and photocatalysts. Zinc Oxide (ZnO) is a photocatalyst capable degrading washing waste. This study aims investigate ability ZnO as in independent variables experiment were mass contact time. used 0.5, 0.75, 1 gram time 2, 3, 4 hours. experimental r...

Suspended substances in car washes can often be easily removed by physicochemical processes. The main problem is to remove dissolved such as detergents from the water. In this study, a biodegradable substance Sodium Lauryl Sulfate (SLS) was wash wastewater use of Phragmites australis subsurface constructed wetland. For 4 plexiglass reactors having an effective volume 10.8 L with dimensions 15cm...

In recent years, people’s environmental awareness has increased. The high density of the urban population caused a considerable increase in demand for car washing services, which created large quantities wash wastewater. main pollutants wastewater are detergents, dirt, oil, and grease. Untreated released into rainwater sewer systems or other water bodies may pollute generate excessive bubble fo...

Exposure to hydrofluoric acid (HF) causes corrosive chemical burns and potentially fatal systemic toxicity. Car and truck wash cleaning products, rust removers, and aluminum brighteners often contain HF because it is efficient in breaking down roadway matter. The death of a truck wash worker from ingestion of an HF-based wash product and 48 occupational HF burn cases associated with car and tru...

background: car wash waste water contains several contaminants such as organic matter, oil, grease, detergents and phosphates, all of which are harmful for the environment. in this study, the application of electrocoagulation (ec) to treat car wash waste water has been studied, and the operating parameters optimized. the electro-fenton (ef) for further contaminant removal was also investigated....

The application of advanced oxidation processes (AOPs) to the treatment of an effluent contaminated with hydrocarbon oils was investigated. The AOPs conducted were Fe2+/H2O2 (Fenton's reagent), Fe2+/H2O2/UV (Photo-Fenton's reagent) and UV-photolysis. These technologies utilize the very strong oxidizing power of hydroxyl radicals to oxidize organic compounds to harmless end products such as CO2 ...

Different techniques of car washing are presented in this paper, along with issues of water use, water contamination and its purification. Nowadays, technological advancements in the car wash industry fall into specific categories such as, new washing technologies (touch-free and hybrid washing technology), advanced water recycling systems (based on biological water treatment), water desalinati...
