A clear water filtration setup for producing deionized water typically involves several stages. Initially, pre-filtration using sediment and activated carbon filters removes large particles and organic compounds. This is followed by a reverse osmosis (RO) system that eliminates most dissolved solids. The water then passes through deionization (DI) resins, which use ion exchange to remove remaining cations and anions. Finally, post-filtration, including polishing filters and UV sterilization, ensures the highest purity by removing any residual impurities. Proper storage and distribution systems maintain water purity, making it suitable for high-purity applications. Regular maintenance and monitoring are essential for sustained performance.
