Abstract
A side channel clarifier for use in wastewater treatment devices employing the circulation of water in a tank having a circuitous path for the purposes of aeration and biological digestion of wastes, wherein the clarifier is mounted in the wall of the channel so that the main flow of water in the tank is undisturbed, and that a portion of that flow is diverted into as quiescent clarification zone, where an inclined baffle collects settled sludge and returns that sludge to the main flow for further decomposition. Siphoning means are provided to ensure the return of a substantial portion of the sludge to the main flow before stagnation occurs and without disrupting the inflow of wastewater into said clarifier. Means are also provided to separate the clarified effluent for further treatment.
