overview :
The effluent water quality standards for reclaimed water reuse equipment:
Industrial production covers a wide range, and different departments have different requirements that vary greatly. The sewage situation is also very complex. From a practical perspective, there are mainly three types of requirements for industrial water use:
1. Cooling reclaimed water: It does not form scale or produce excessive foam during heat exchange and does not cause corrosion to the water system. For specific details, please refer to the "Standard for Industrial Cooling Water".
2. Workshop production water: This type of water has relatively high requirements and generally needs to meet the standards of tap water or pure water. It is mainly used for production water on the production line or for product cleaning.
