Abstract

resumo patente de invenção: "processo para desaguamento de lodo". a presente invenção refere-se a um processo para desaguamento de lodo, em que uma solução aquosa de agente floculante polimérico é adicionada ao lodo, em que o lodo compreende um componente a ser removido pelo agente floculante, que é adicionado ao lodo, em que para limitar a proporção residual do agente floculante em um filtrado do lodo, o processo compreende uma primeira e/ou uma segunda etapa, em que a primeira etapa compreende: medir uma primeira informação de teor relativa à quantidade total de material sólido no lodo (orgânico e inorgânico); e medir uma segunda informação de teor relativa a um teor de material de areia no lodo, em que as primeira e segunda informações de teor são usadas para controlar a adição da solução aquosa do agente floculante polimérico ao lodo, em que a segunda etapa compreende medir uma informação material relativa a uma propriedade material do filtrado, em que a informação material é usada para controlar o teor do agente floculante polimérico no filtrado.
