Reverse Osmosis Systems are water filtration devices that purify water by removing contaminants through a semi-permeable membrane. These systems effectively eliminate impurities like dissolved salts, bacteria, and chemicals, providing clean and safe drinking water. They are available in various capacities suitable for residential, commercial, and industrial applications, ranging from compact under-sink units to large-scale installations capable of filtering thousands of gallons per day. Key features include multi-stage filtration, energy-efficient operation, and designs tailored to different water treatment needs, making them ideal for improving water quality in homes and businesses.
