Scaling in the acid production wastewater from pyrite
Thread Content
Our factory uses pyrite to produce sulfuric acid, and the slag wash water is recycled. Currently, the sulfuric acid slag flushing water contains calcium sulfate, which tends to crystallize and block the pipes. How can this be resolved?
Multi-stage sedimentation tanks are used, with overflow circulation; the sludge settled in the sludge removal tank is regularly removed and taken away
Our company specializes in solving the technical challenges related to the chemical cleaning of calcium sulfate scale
If you are sure it is calcium sulfate scaling, use a calcium sulfate cleaning agent with a pH of 7.0±0.1; it is non-corrosive, reacts rapidly and intensely, and removes calcium sulfate at a rate visible to the naked eye. If you’re interested, I can send you samples for free to test; I guarantee they’ll work well for you.
