Abstract
Ferric chloride contained in liquid waste streams comprising higher boiling chlorinated hydrocarbons may be substantially reduced by contacting the waste stream with an amount of water sufficient to convert a substantial amount of the ferric chloride in said stream to solid ferric chloride hexahydrate, and then removing the solid hexahydrate from the waste stream for instance by filtration.
