Abstract

"MéTODO E INSTALAçãO INDUSTRIAL PARA ESPESSAMENTO DE LAMAS DERIVADAS DE TRATAMENTO DE áGUAS ATRAVéS DE FLOCULAçãO-DECANTAçãO COM FLOCO LASTREADO". A invenção refere-se a um método para espessamento de lamas derivadas a partir de uma unidade de tratamento de águas através da floculação-decantação com floco lastreado com micro-areia ou outro material granular denso usando um tratamento do líquido por ciclone (1) de decantação da lama. A invenção é caracterizada pelo fato de que ela compreende estágios sucessivos que consistem em: remoção de gases (3) da lama de transbordamento do tratamento do líquido por ciclone (1) proveniente da unidade de floculação-decantação lastreada, o referido estágio de remoção de gases sendo realizado sobre uma superfície de desgaseificação correspondente a uma velocidade superficial de desgaseificação de menos de 100 m/h; injetar pelo menos um agente floculante (4) na referida lama; e espessar a referida lama em pelo menos um espessador lamelar de lamas (6), com uma carga no piso de repouso calculada na superfície do piso do espessador maior que 200 kg de matéria suspensa por m^ 2^ por dia e a concentração da lama extraída maior que 10 g/1.
