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.

Abstract: This invention provides a surprisingly efficacious combination useful for inhibiting microorganism growth, particularly in aqueous slurries containing mineral ore. In particular embodiments, the invention provides an antimicrobial composition comprising 1-(3-chloroallyl)-3,5,7 triaza-1-azoniaadamantane chloride and 2-bromo-2-nitropropane-1,3-diol. The invention also provides a method for inhibiting microbial growth in an aqueus mineral or ore slurry, e.g. a kaolin slurry. The method includes the step of adding to the slurry a microbiocidal composition of 1-(3-chloroallyl)-3,5,7 triaza-1-azoniaadamantane chloride and 2-bromo-2-nitropropane-1,3-diol.
Abstract: A polycationic microbicidal and algaecidal agent containing as an active ingredient a polymer comprising repeating units represented by the formula (I) and having a number average molecular weight of at least 1,000, and a microbicidal and algaecidal method using the polymer: ##STR1## (wherein A is a single bond, an oxygen atom, a phenylene group, a dioxyethylene group or a tetramethyldisiloxane group, X.sub.1.sup.- and X.sub.2.sup.- may be the same or different and are counter anions in quaternary salts, p and q may be the same or different and are integers of from 1 to 6, and m is an integer of from 1 to 6, provided that A, X.sub.1.sup.-, X.sub.2.sup.-, p, q and m may be the same or optionally different for every repeating unit).

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: A composition comprising a water-dispersible ionene polymer and a water-dispersible di-lower-alkyl ammonium halide polymer (for example, a polymer of dimethyl diallyl ammonium chloride) is disclosed. These polymers are present in the composition in a ratio effective to function synergistically as an algistatic or algicidal agent when an effective amount of the composition is dispersed in a body of water. Examples of suitable bodies of water are swimming pools, spas, lakes, rivers, or water in an industrial water system, such as a cooling water system. Also, a method of treating water which is susceptible to the growth of algae is disclosed. The method is carried out by incorporating in the water an at least algistatic amount of the composition.
