Technical discussion: What is the production cost of pure water?

This post was last edited by hesonchang214 on 2010-3-25 at 14:53. Our company is a chemical manufacturing enterprise that uses large amounts of pure water (sometimes referred to as deionized water). This pure water is produced by treating deep well water through processes such as disk filtration, ultrafiltration, reverse osmosis, and mixed-bed filtration. I’m looking for an estimate of the production cost per ton of this pure water; I urgently need this information for cost calculations related to technical upgrades. If anyone knows the relevant figures, please share them with me. Thank you.
Ours is first-stage reverse osmosis, with a cost of around 3.04 yuan.
One more thing: the costs mentioned here include the expense of water, labor costs, the cost of chemicals added, as well as equipment depreciation. All these costs are added together, and after taking into account factors such as the water production rate, a range can be given; for example, 5–10, 10–15, 15–20, or 20–25, 25–30
In the process plan developed by the water treatment company for our water quality, the production cost of pure water is approximately 3.00 yuan.
Including all costs, it should be over five yuan I guess
It is related to the quality of your raw water, as well as the quality of desalinated water required.
Agree with 6L’s opinion. Different raw waters affect operating pressure, yield, dosage of chemicals, and so on – these are all direct factors that influence costs.
The cost of producing desalinated water using tap water is 10 yuan per ton, while using reclaimed water can save 2–3 yuan per ton.
The price can only be determined by checking the quality of the raw water
The cost of water produced by the reverse osmosis system is approximately 5–6 yuan per ton; this figure takes into account expenses such as bank loans, labor costs, electricity costs, and chemical costs. I really want to know how the operating costs of reverse osmosis systems costing 2 to 3 yuan are calculated
This treatment cost is indeed related to the quality of the raw water. According to LZ, it should refer to the total production cost, rather than the processing cost. Based on the processing procedure mentioned by LZ, the total production cost should be between 10 and 15 yuan.
