The working principle of the commercial direct drinking water system mainly includes the following steps:

‌Raw water tank‌: Store raw water for subsequent treatment.

‌Pretreatment system‌: Remove suspended matter, silt, colloids and other impurities in the raw water through filter materials such as activated carbon and quartz sand.

‌Reverse osmosis system‌: Use reverse osmosis membrane technology to remove harmful substances such as soluble solids, bacteria, viruses, etc. in water.

‌Ultraviolet disinfection system‌: Use ultraviolet irradiation to kill bacteria, viruses and other microorganisms in water.

‌Water storage tank‌: Store purified water for users to drink

Key technologies and components of direct drinking water system‌:

‌Reverse osmosis membrane technology‌: This is the core filtration technology that can remove bacteria, viruses, heavy metals, organic matter and other impurities in water to ensure water quality safety.

‌Ultraviolet disinfection‌: Kill residual microorganisms through ultraviolet irradiation to ensure that the water quality meets the standards for direct drinking.
