How can the concentrated water produced after purifying water using utility systems be utilized effectively?
It depends on the salt content and the level of COD concentration; decisions regarding utilization are made based on these two key parameters. However, it’s generally difficult to make effective use of concentrated wastewater
Check the water quality parameters to determine whether to use it for recirculating water or for other purposes
Can it be used directly for landscaping? However, the total hardness is around 800 mg/l, and the total salt content is around 1100 mg/l
The data mentioned by the poster can be used. Direct greening is not a big problem.
Regarding landscaping, as long as very special plants are not planted, the water quality is sufficient; however, for certain plants, the salt content may need to be taken into consideration.
I found the water quality standards for general household use, which require a total hardness level of less than 450 mg/l; my water exceeds this limit!
Reusing this water is indeed very difficult, but if your company has a coal yard, it is likely possible to use it for spraying wastewater in that yard
I’m at a steel plant, where the concentrated water is used for slag removal in steelmaking.
Reverse osmosis concentrate is an excellent source of water for reuse; with appropriate pretreatment and further desalination, the water produced by this system is of higher quality than the water used for circulation purposes, or it can be used directly as feedwater for the reverse osmosis process in a pure water system.
10th floor: Could you explain in more detail the pre-treatment and desalination methods you mentioned?
