Abstract

SISTEMA DE TRATAMENTO DE áGUAS DE LASTRO DE NAVIOS, PLATAFORMAS DE PETRóLEO E DE EMBARCAçõES EM GERAL, ATRAVéS DE PROCESSO EM REATOR ELETROQUìMICO. A presente invenção se refere à utilização de um reator eletroquímico para esterilização e desinfecção de água do mar e de águas de lastro de navios, de plataformas de petróleo através da passagem em reator eletroquímico, que poderá ser instalado e operado tanto a bordo, como nos portos e terminais aquaviários. Podendo operar tanto em fluxo contínuo quanto em batelada. A água de lastro a ser esterilizada é bombeada continuamente, passando através de um sistema de filtragem, circulando entre catodos constituídos de placas, grades ou telas de titânio e anodos constituídos por placas, grades ou telas de titânio revestido com óxidos metálicos, que não estão separados por qualquer meio físico, exceto a própria solução a ser tratada. A água de lastro poluída com elevada concentração bacteriana (média de 10¬ 6¬ a 10¬ 8¬ UFC/l00 mL) foi esterilizada, a partir da aplicação de uma intensidade de corrente de 6,5 A e uma tensão entre catodo e anodo de cerca de 3,9 V, com tempo de residência médio de 6 minutos. Neste regime o consumo energético específico para geração do íon hipoclorito usado no processo de esterilização foi de 7,9 kWh/kg.
