Wastewater Treatment at KPP IPAL Wahana Sejahtera, Ngebel Gede Distrik, Using Microbubble Technology and Ultraviolet Light with Environmentally Friendly and Sustainable Solar Energy

Abstract

The need for environmentally friendly and sustainable wastewater treatment technology is increasing with industrial growth and urbanization. This service aims to examine the effectiveness of combining water bubble and ultraviolet (UV) light technologies, and also utilizing solar energy as the primary resource in the wastewater purification process. The methods used include wastewater aeration with a micro air bubble system to increase dissolved oxygen and aid in the degradation of organic compounds, followed by UV light exposure for the inactivation of pathogenic microorganisms. Solar energy is used as an alternative resource to operate the aeration system and UV lamps, thus supporting energy efficiency and reducing the carbon footprint. The research results show that this technology combination is capable of significantly reducing Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) levels, while also lowering the number of indicator bacteria to meet the established water quality standards. Thus, the integration of solar energy-based air bubble inside of waste water technology and UV rays has the potential to be an innovative, sustainable, and environmentally friendly solution for treating residential and small-scale industrial wastewater. This service program has been socialized by the Vocational School Health Information Service, UGM, to the user community (KPP Wahana Sejahtera), located at Ngebelgede, Drono RT6, RW33, Sardonoharjo, Ngaglik, Sleman, partners, and the Sleman Environmental Agency, so that the benefits of the program, installed tools, and instruments are realized, and the stakeholder communities understand the importance of the program's sustainability for environmental preservation. With this program, the final result is odour-free water with low turbidity.
