ENVIRONMENTALLY-FRIENDLY MICROBIOCIDAL CONTROL IN AQUEOUS SYSTEMS WITH THE AID OF A FEEDER

摘要

In forming an aqueous microbiocidal solution, the solution is formed by passing water through a bed of at least one 1,3-dibromo-5,5-dialkylhydantoin in non powdery particulate form disposed in a feeder tank. Described are the particular 1,3-dibromo-5,5- dialkylhydantoins used and their compacted forms together with the particular design features of the feeder tank (10).
