Advanced Lightweight Photocatalytic Composite Membrane to Remove Biological Pollutants from Wastewater

Sanjay, Dhirendra Pratap Singh, Sanjay Mishra and Tabish Alam

Abstract

The objective of this study is to design a novel lightweight photocatalytic composite membrane which can be utilized to remove biological contaminants from wastewater. The developed membrane is not only safe and economical but also environmentally friendly. The photocatalytic composite membrane is made up of zinc oxide (ZnO), titanium oxide (TiO2), copper oxide (CuO), silver nitrate (AgNO3), and hydraulic cement as a binding agent. TiO2, ZnO, AgNO3, CuO, and sand were mixed in the ratio of 4:2:2:25:67, respectively. The biological pollutant (BP) inactivation test with the photocatalytic composite membrane reduced the total number of bacterial colony forming unit (CFU) by 96.37%, 97.25%, and 97.78% immediately after filtration in 15 minutes at an initial concentration of 523, 400, and 225 CFU/ml, respectively. In under 15 minutes, at a concentration of 225 CFU/ml, this photo catalytic composite membrane eliminated 97.78% of all bacterial colonies, making the sample sterile. The experimental analysis reveals the suitability of sustainable, cost-effective, and environmentally friendly approach to purify wastewater. The developed membrane takes only 15 minutes to kill or disinfect around 98% of bacteria that were born as a result of biomedical or other contaminants.
