BioFerric-Flocculant Enhanced Primary Treatment Process (BEPT) for Sewage Treatment

摘要

The present invention relates to one step “BioFerric flocculant enhanced primary treatment” (BEPT) process for domestic sewage treatment. More particularly, it relates to a novel composite flocculant consisting of acidophilic bacteria, and bacteriogenic flocculants for sewage flocculation and settling that enhanced the sewage treatment process by minimizing the chemical uses and steps and direct dewatering of sludge without preconditioning.
