Cost of reclaimed water reuse

Let’s discuss the costs of reclaimed water reuse
This is related to the quality of the raw water and the standards for reclaimed water, making it difficult to provide specific numerical values for measurement.
Reclaimed water generally involves treating the wastewater from a system, and then reusing it after treatment. In terms of annual costs: equipment depreciation, expenses for various medications, costs related to maintenance and replacement of wear and tear parts, labor wages, electricity consumption by the system, steam consumption, costs for domestic water use, and other basic management expenses. The sum of all the above categories constitutes the cost for reclaimed water reuse. I’m not sure if it’s clear enough – it varies from factory to factory and requires calculation.
This question is too broad and also very vague. The friend upstairs is right – there are differences in the raw water, the treatment methods used, the requirements for the treated water, as well as varying requirements for the return water, and so on. . . . In short, comparison should have a similar premise. I hope we can discuss personalization!
The issue of the cost of reclaimed water is related to the fact that reclaimed water is obtained by further treating wastewater to meet specific standards. The costs involved in this process include expenses for chemicals, energy, labor, etc. In reality, these costs are slightly lower than those associated with wastewater treatment, ranging approximately between 0.15 and 0.25 yuan per ton.
According to water treatment experts, the cost of installing a reclaimed water reuse system in the Nanjing area is approximately twice that of using fresh tap water. According to this theory, water prices are currently low, and ordinary factories are reluctant to install such facilities
A calculation was once done; by adding up some of the costs mentioned for the 3rd and 5th floors, the estimated cost was over 1 yuan. Users of reclaimed water may also face certain restrictions, such as being allowed to use it mainly for watering plants and the like. If used as process make-up water, its cost will be higher.
