Can the reclaimed water from wastewater treatment plants be used as industrial water?
Thread Content
Hello everyone: We are building a new chemical plant in Inner Mongolia. The site chosen for the project does not have any water sources, so it is necessary to lay pipelines 20 km away from the project site in order to use reclaimed water from a sewage treatment plant. Is it possible to use the reclaimed water from such a sewage treatment plant? (Mainly for circulating water systems, demineralization units, and fire-fighting water use). What is the approximate cost of laying pipes over 20 km? Daily water consumption is 1500 m3, thank you!

Reused wastewater can be utilized, especially in areas where water is scarce. For laying 20 km of pipelines, I estimate that the cost of materials alone, excluding labor costs, would be around 700,000.
It is perfectly fine to use reclaimed water as circulating water and for fire-fighting purposes. For circulating water, it is necessary to control the COD level, and bactericides should be used as appropriate; everything else can be handled normally. As for desalinated water, the desalination process needs to be determined based on the quality of the reclaimed water, and it can be used accordingly. I don’t know how much the pipes cost. We can communicate more about water treatment! VX:Azsyx1314:)
After being treated with appropriate methods, reclaimed water can be used for various purposes, such as as fire fighting water, circulating water, and process water. Many fermentation plants and chemical plants in Inner Mongolia, Xinjiang, and Ningxia are doing this now. If necessary, we can have a good discussion.
The water quality standards for recycled wastewater include Grade A and Grade B; is Grade B suitable for industrial use?
The original poster didn’t provide very specific details; it would be possible to ask what process is used for the reuse of reclaimed water in the factory What are the design standards for reclaimed water output? What are the water quality standards for circulating water and desalinated water? I believe that after checking this information, you’ll know the answer yourself: lol
Thank you for the reminder from above. Our factory is involved in a natural gas liquefaction project located in Inner Mongolia; the project is still in the planning stage. There are no sources of water for production or domestic use in the vicinity, so we intend to use the reclaimed water from the sewage treatment plant that is 10 kilometers away from our site. The water will be used mainly for replenishing circulating water, desalination processes, fire fighting purposes, as well as for domestic use. We are currently working on a plan to see if it’s feasible Consider various factors (pipeline installation costs, land acquisition, etc.).
