Seek advice on the concentration of pure dilute sulfuric acid
Thread Content
Gentlemen, the dilute sulfuric acid produced as a by-product in the acid production process has a concentration of around 2.5%; it is pure and transparent, just like mineral water. Are there any ion exchange or membrane separation methods that can increase the concentration of this dilute sulfuric acid from 2.5% to around 7.5%? If possible, please provide the information. Thank you
Electrodialysis – well, we have case studies of projects in the metallurgy industry that were built and operated by those industries themselves
For low-concentration waste acid, the cost of concentration is too high; it’s like turning tofu into meat at an exorbitant price. Can’t it be mixed with acid? Can it be concentrated?
If the volume of liquid is high, electrodialysis is still needed to reduce it and then concentrate it. The cost is too high if concentration is achieved directly
How can I get in touch with you to ask about the specific technical details?

Dilute sulfuric acid can be concentrated using membranes, to a concentration of over 10%. Baidu search for Hefei Woteng Membranes
