Zero discharge of water reuse
Zero discharge of water reuse
Water characteristics
Industrial water reuse is to take industrial wastewater through deep technical treatment to remove various impurities, remove toxic and harmful substances and certain heavy metal ions that pollute the water, and then disinfect and sterilize the water, which is colorless, odorless, clear and transparent, and reaches or better than the national standard for miscellaneous water (or related regulations), and is widely used in enterprise production.
Zero discharge treatment process
Enterprise water - biochemical treatment - ultrafiltration - reverse osmosis - high pressure reverse osmosis - evaporation system

Process Introduction |
The plant water is mixed and then biochemically treated to reduce the organic matter ammonia nitrogen in the wastewater, the effluent is treated by ultra-filtration, reverse osmosis and high-pressure reverse osmosis, the produced water is returned to the plant for recycling, and the final concentrated water is evaporated and crystallized, most of the water in the whole process is reused, and only a small amount of sludge and crystallized salt is discharged from the system, thus achieving the purpose of zero discharge of water reuse. | |
