รายงานวิจัย -- มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร, 2565In Klong Rangsit, Pathumthani province, where the water entering was filtered by a prototype quality water machine and autonomously controlled by pumps and sensors, this research tested improvements to water quality. It employs a total dissolved solid and temperature sensor as part of the consideration of the water quality criterion in accordance with the water quality requirements of the Pollution Control Department, and is 99% successful in treating contaminants in water. According to the Pollution Control Department's water quality criteria, which are divided into four main categories: very good water quality, good water quality, degraded water quality, and very degraded water quality, it is used in the analysis of the division of the four categories of water quality. Machines for producing good quality water to maintain water sanitation during COVID-19 and anticipated flooding across the nation. This is simple to use. Since the made quality water machine prototype has a battery to back up the power for the pump and UV lamp control by filtering water through various stages of a quality water producer prototype, it is simple, can generate clean water for usage, and can be carried. No energy is used, and there is no residue filtration effluent. It eliminates 99 percent of water pollutants and has no color.Rajamangala University of Technology Phra Nakho
