Flotation technique with coagulant and polymer application applied to the post-treatment of effluents from anaerobic reactor treating sewage

This paper presents the results of a study performed with a lab-scale batch DAF unit fed with previously coagulated (with FeCl3 and/or cationic polymer) effluent from a pilot-scale expanded bed anaerobic reactor treating domestic sewage. The association between ferric chloride and polymers was studi...
