The reclaimed water reuse system is a system that collects the wastewater from the hard equipment cleaning machine in the supply room, the circulating cooling water from the high-temperature sterilizer, and the washing water from the industrial washing machine, and then passes it through the sewage treatment system and reverse osmosis system to remove various impurities, toxic and harmful substances, and certain heavy metal ions that pollute the water body. The produced water is colorless, odorless, clear and transparent, meeting or better than the water quality standards for reuse. Reuse after softening or reverse osmosis treatment. This system has low energy consumption, saves operating costs, and adds an energy monitoring system, with a water saving rate of over 90% and a high degree of automation.
