Introduction: Carwash are industries that consume large amounts of water and results wastewater that have different type of pollutents(detergents, oil and grease, metals, etc.). Enough treatment of carwash wastewater is important and could be protect surface and ground water. Therefore, in this study ozonation process was used for carwash wastewater that generated from washing the cars in...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
This paper presents development of Automated Carwash using Programmable Logic Control (PLC) Controller, for supporting their technologies and protocols. The main objective the study is to reduce volume water use in car wash help mitigate possible hazard from prolonged chemical response or any potential injury that might occur. In Kuwait, carwash among activities consume a great deal desalinatio...
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...
background detergents and difficulties of their presence in the water and wastewater cause various problems such as foam production, anomalies in the growth of algae, and accumulation and dispersion in aqueous environments. objectives the aim of this study was to examine and compare the moving bed biofilm reactor with another reactor without media (carries) for anionic surfactants removal. mate...
One of the most significant urban services is carwash, which generates large amounts wastewater containing a variety pollutants, including sand, gravel, suspended solids, surfactants, oil products, diesel cleaners, etc., that may cause environmental pollution when transferred to sewage system without any treatment. The effective treatment crucial prevent as well recycle water source. Contaminan...
This paper assesses a bench-scale carwash wastewater treatment system's removal efficiency based on coagulation-flocculation and household-type activated carbon filter water ozonator. For the experiment, that went through an oil/water separator (OWS) from medium-sized facility located in dense commercial area Barranquilla, Colombia, was collected. The study evaluates following parameters: quali...
