TREATMENT OF CHLORINATED ISOCYANURATE WASTE STREAMS

摘要

Aqueous waste streams containing dissolved chlorinated isocyanurate values, that is, chlorinated isocyanuric acids and their salts, are treated with a compound selected from the group consisting of sulfur dioxide and an alkali metal sulfur-containing reducing compound to dechlorinate and precipitate the isocyanurate values therefrom. The treatment effects recovery of isocyanurate values, and is an effective pollution control means which can operate with existing commercial facilities.
