A process for removing fluoride and phosphorus type contaminants from acidic waste water.

摘要

An ion-exchange process for removing fluoride and phosphorus type contaminants from acidic process waste waters, includes contacting the waste water with a strong base ion-exchange resin to load SiF6<2><-> on to the resin. The resin is then regenerated with a compound which strips the SiF6<2><-> from the resin.
