A PROCESS FOR REMOVING FLUORIDE AND PHOSPHORUS TYPE CONTAMINANTS FROM ACIDIC WASTE WATER

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 on to the resin. The resin is then regenerated with a compound which strips the SiF6 from the resi...
