Abstract

MENENDEZ GUTIERREZ, Carlos. Secondary sedimentation in biological wastewater treatment. Ing. hidrául. ambient. [online]. 2022, vol.43, n.3, pp. 24-33.  Epub Oct 22, 2022. ISSN 2788-6050.

In conventional biological wastewater treatments, biological and physical processes co-exist, one as important as the other, on which the purification efficiency depends. Among the latter secondary sedimentation can be mentioned. Malfunctioning of settlers, whatever be the cause, can have a significant impact on the expected efficiency of treatment.

Keywords : IVL; sludge bulking; sedimentation; biological treatment.
