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...

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...

Carwash wastewater (CWW) contains grease, oil, hydrocarbon residues, heavy metals, and surfactants, posing severe impacts to the environment human health. Accordingly, various physical, chemical, biological processes for CWW treatment have been demonstrated in recent research. In this study, a bibliometric approach was performed comprehensively illustrate progress, current direction, future per...

Carwash wastewater (CWW) can be a significant source of environmental pollution due to the diversity and high concentrations contaminants it contains. This toxic contain several different heavy metals that if left untreated, enter surface sub-surface waters. Innovative, nature-based solutions such as low-impact development (LID) technologies may provide an eco-friendly CWW treatment process is ...

Huge amounts of fresh water are used in the concrete industry every day. The quantity and quality play important roles determining quality, strength, setting time, durability cement-based materials (CBMs), such as paste, mortar, concrete. Freshwater systems under pressure due to climate changes, industrialisation, population growth, urbanisation, lack proper resource management. potable has res...
