Fluorine chemical industry: treatment technologies for fluorine-containing wastewater
Thread Content
The new process, which uses DuSheng special ion exchange resin as the medium in fluoride removal equipment, can effectively solve the aforementioned problems and protect people from the harmful effects of high fluoride levels. Features of ion exchange process for fluoride removal: 1. Low cost and low investment; can be reused for over 5 years ； 2. Low operating costs and low water production expenses; accuracy can reach below 1 PPM with stable water output ； 3. Easy to operate: Automated or semi-automated operation is available, with no need to adjust the pH value ； 4. The equipment is easy to install and use; it can be connected directly to variable-frequency pumps in deep wells, with the water outputting directly into the municipal water supply network. There is no need for a water storage tank or a discharge tank, nor is any secondary pressure enhancement required ； 5. The new type of fluoride removal equipment has a high water utilization rate, of over 98–99% ； 6. The equipment requires little floor space, and the amount of material used is much less than that of media with similar functions. 7. Fluorine can be recycled
Investments are determined based on the water volume. The maximum level of fluoride allowed in drinking water is 3 mg/L at most, and the costs involved are not in the millions; considering it as a project aimed at improving people’s livelihoods, it actually represents a relatively low investment.
Photovoltaic plants and IC chip factories: Most industries in the silicon sector use hydrofluoric acid, or even mixed acids. The best way to handle waste hydrofluoric acid is to reuse the fluorine resources. My approach involves removing silica from the waste acid; the current removal rate is 99%, after which the fluoride ions are converted into compounds. This allows for the full utilization of fluorine resources, in line with resource recycling policies
What is the economic viability of treating fluorine-containing wastewater on an industrial scale?
Ansteel’s fluoride-containing wastewater treatment projects also cover fluoride removal from mine water
That’s too amateurish – recyclable fluorine? How to recycle it? Blowing up one’s own chest
There is a good technology for treating fluoride-containing wastewater; it has been used to handle such projects for various glass thinning companies. The technology and processes for the comprehensive utilization of fluoride-containing wastewater achieve a fluoride utilization rate of over 90%. Website: http://dshtech.cn/newsinfo/1672523.html
