I would like to ask: If the factory adds a few more wastewater treatment units on top of its existing facilities, without constructing any buildings or tanks, what procedures are required? Is a construction permit necessary?
Wastewater treatment equipment? If there are no regulated categories, it can be purchased and installed directly.
No need to report? A construction permit?
If there are no significant changes to the wastewater treatment processes, the company’s internal process change procedure can be followed； As a precaution, it is recommended to consult the local environmental protection authorities regarding the construction procedures. Thank you!
