Sedimentation has been the mainstay process for solid-liquid separation in the water and wastewater industry since its inception, based upon the simple fact that because solids are heavier than water, they will settle in a quiescent basin. This belies some of the complexities of the detailed design of settlement basins, be they clarifiers or thickeners, and the mechanisms required to ensure that they function correctly and reliably in the given application. Ovivo’s expertise and offering in this field is second to none. Our application experience covers: circular, rectangular, conical and flat bottom tanks. Various clarifier (scraper) bridges are available together with innovative designs to encourage settlement and mixing of coagulants when used.
