Abstract

"SISTEMA PARA TRATAMENTO DE áGUA DE LASTRO, EMBARCAçãO, MéTODO E SISTEMA DE CONTROLE DE ORGANISMOS EM áGUA DE LASTRO DE UMA EMBARCAçãO, E, SISTEMA PARA GERAçãO DE BIOCIDA MODULAR". São descritos aparelhos e métodos de um sistema para tratamento de água de lastro (10). O sistema para tratamento de água de lastro (10) inclui um sistema de controle (30) e um sistema de tanque de lastro (60). O sistema de controle (30) controla a concentração de um biocida no sistema de tanque de lastro (60). Em adição, o sistema para tratamento de água de lastro (10) pode ser implementado em uma embarcação (9). O sistema de controle de lastro (30) é capaz de controlar a concentração de um biocida no sistema de tanque de lastro (60) por meio do controle da quantidade de biocida alimentado no sistema de tanque de lastro (60) a partir do sistema para geração de biocida (20). Também, a água de lastro de uma embarcação (9). Um método representativo inclui a provisão da água de lastro, e o tratamento de água de lastro com dióxido de cloro.
