Which one has 30% waste sulfuric acid?
Thread Content
For adjusting the pH in wastewater treatment, we are located in Tongling, Anhui. Is there any 30% waste sulfuric acid available in the vicinity that is relatively clean enough for use in this purpose? If it’s not clean enough, the wastewater will have to be discharged directly; no other wastes are allowed
Contact the poster of this thread to see if it’s possible to remove the sparks. http://bbs.hcbbs.com/thread-1425151-1-1.html
Thank you for the reminder; I’ve already gotten in touch
We have 30-35 of sulfuric acid, but it’s a bit far away. It’s from Shouguang, Shandong – does this also require a certificate?
The distance is indeed too great; transportation is not cost-effective
Anantada has it; there’s a lot of waste acid from titanium dioxide production
We are involved in environmental protection projects, and pH adjustment is used before water treatment and discharge. The environmental protection agency has clearly stated that the sulfuric acid generated as a by-product of titanium dioxide production contains pollutants, and therefore it cannot be used in environmental protection projects.
How much sulfuric acid is needed? Can the residual acid from silicon wafer cleaning be used? The detection index is of AR grade
The amount used is not large – around 20 tons per day at 5%. The exact amount required depends on the quality of the water to be treated. If your water quality is good enough, it should work, but you need to take into account costs such as transportation fees. I haven’t purchased it yet; I’m preparing to prepare it using concentrated sulfuric acid
The waste sulfuric acid from chlor-alkali enterprises should work, there are so many such enterprises in Anhui
