Abstract

"MéTODO PARA A REMOçãO DE PELìCULA BIOLóGICA". A presente invenção proporciona um método para a remoção de película biológica, lama floculante em volume ou lodo em volume biologicamente ativo a partir de um sistema aquoso. O método envolve a adição de uma ou mais hidantoínas cloradas tais como o dicloro- ou mono- cloro dialquil hidantoína ao sistema aquoso. De forma alternativa, a hidantoína ciorada pode ser formada in situ através da adição de uma fonte de cloro e uma hidantoína alquilada de forma separada ao sistema aquoso. A invenção é vantajosa de forma específica devido a marcante foto estabilidade das soluções de hidantoína clorada mesmo quando expostas a luz do sol.
