Abstract
A process for treating acidic process waste water containing SiF.sub.6.sup.2- is disclosed. The process is carried out by contacting the waste water with a strong base ion exchange resin and loading SiF.sub.6.sup.2- onto the resin. Phosphate ions are then removed from the waste water by raising the pH of the waste water to between about 5.0 and 7.0 and contacting the waste water with a strong base ion exchange resin and loading phosphate ions onto the resin.
