Abstract

<B>"PROCESSO PARA TRATAMENTO DE CORRENTES AQUOSAS QUE COMPREENDEM BIO-SóLIDOS"<D> A presente invenção refere-se a um processo que pode ser utilizado para a clarificação de correntes substancialmente aquosas, e opcionalmente para a separação de bio-sólidos, especialmente proteína provenientes de operações de processamento de alimentos, os qual compreende a colocação de uma corrente aquosa, que inclui bio-sólidos, em contato com um colóide inorgânico aniónico e um polímero orgânico, para flocular os bio-sólidos.<B> "PROCESS FOR TREATING AQUEOUS CHAINS THAT UNDERSTAND BIO-SOLIDS" <D> The present invention relates to a process that can be used for the clarification of substantially aqueous currents, and optionally for the separation of bio-solids, especially protein from food processing operations, which includes placing an aqueous stream, which includes bio-solids, in contact with an anionic inorganic colloid and an organic polymer, to flocculate the bio-solids.
