Abstract: Compositions and methods are disclosed for sanitizing aqueous media, which combine a chlorine-source composition and a glycoluril-source composition. The compositions are added together or separately, continuously or periodically, and by any of a variety of methods. The glycoluril compound stabilizes the chlorine and prolongs its useful life as a microbicidal agent while additionally reducing the formation of chloramines, trihalomethanes and odors.

Abstract: Disclosed are solid oxidizer compositions that provide either hypochlorous or hypobromous acid for disinfecting water systems comprising either of the following mixtures: (a) approximately 50-99.99% by weight of trichloro-s-triazinetrione and 0.01-50% by weight of glycolurils of the following structure: ##STR1## wherein R and R.sub.1 are members selected from the group consisting of hydrogen, lower alkyl radicals of from 1-4 carbon atoms and phenyl, and X is selected from the group consisting of hydrogen, chlorine and bromine and a, b, c, d and e are integers of from 0-1;and (b) approximately 50-99.99% by weight of trichloro-s-triazinetrione, 0.01-50% by weight of glycolurils of the above structure (a) and 0-20% by weight of an alkali bromide salt.

Abstract: A novel method and compositions are disclosed for the treatment of water in recirculating water systems. The method includes providing a boron level of at least 20 ppm in the water, continually eroding into the water a compressed sanitizer/algicide component including a halogen source material, a boron source material, and glycoluril, and periodically adding to the water an oxidizing clarifier comprising a chlorine source material, a non-halogen, chlorine source material, and a boron source material. The invention also provides novel water treatment chemicals including the compressed sanitizer/algicide component and the clarifier useful in the foregoing system. The system and compositions are safe and reliable, control algal and fungal growth and generally provide improved water quality for recirculating water systems.
