The HydroRipple速 Clarifier uses a siphon system to intermittently inject water into the clarifier chamber, creating "ripples" that allow for a homogeneous and concentrated sludge blanket. This concentrated blanket is contained by sludge concentrators to maintain contact time between water and sludge. The clarifier requires no mechanical equipment in the water and operates simply and consistently without need for adjustment due to variations in flow or water quality. It is suitable for use with various clarification and treatment processes.
