Comparison of ozone bleaching costs with other bleaching methods?
Thread Content
Currently, treating various types of organic wastewater is quite challenging, and there is also the issue of color removal; this has long been a problem for companies dealing with wastewater discharge – what about costs and benefits? Currently, the production of lactam derivatives, aniline-based products, and hydrazine-based products all generates biologically difficult-to-treat wastewater; some of this wastewater has a strong color, and it is quite challenging to reduce its color intensity to below 50 Is ozone intended to be used? What about using ultrasound or physicochemical methods for decolorization – what are the costs? Who did it? Have you done cost accounting and cost comparison? Can we have a conversation? Looking forward to it! !
Ozone alone does not have very strong oxidizing power, and it is essentially ineffective for decolorization; however, it is unclear whether the use of a catalyst improves things.
Oh, our ozone experiment has been successfully tested, with good results! But we don’t know what kind of decolorization methods various companies use, which is why we feel the cost is high! !
The use of resins can be considered for decolorization. For wastewater that is difficult to biodegrade, this method not only enables decolorization but also helps reduce COD levels, thereby improving the biodegradability of the wastewater
When it comes to resins, one has to consider their later regeneration, which is quite troublesome
Direct decolorization using decolorizing agents is common in the market; additionally, organisms can also be used for decolorization, but it is estimated that this water may not be able to handle that. The cost of decolorization is generally 1–5 yuan per ton of water, with significant variations depending on the quality of the water.:)
The experimental data is available; the processing cost remains around 1.1 yuan! The treatment can achieve levels below 50, but the overall cost is estimated to be high; the maintenance costs related to ozone are also expected to be extremely high! :victory::victory:
Ozone decolorization is feasible; however, the production cost is high due to the high electricity costs associated with oxygen generators and ozone generators, while maintenance and labor costs are low. This technology is now quite mature.
Yes, but it’s also difficult to reduce the chromaticity to very low levels; moreover, a long residence time is required, meaning that the ozone needs to react for a long time before consumption can be reduced. This indicates that it is necessary to use a very long or very large reactor chamber or reaction tube in order to achieve low costs: victory::victory::victory:
Do you use pure ozone for decolorization, without employing a catalytic method?
