Abstract: The invention includes an anaerobic solids digestion apparatus comprising a digester, at least one draft tube; at least one nozzle and a biogas source; a method for digesting a waste stream in an anaerobic solids digestion apparatus comprises feeding a waste stream to a digester; reacting the anaerobically biodegradable material in the waste stream with anaerobic bacteria in the digester; introducing a mixed liquor into the digester and mixing the mixed liquor; and a method for minimizing the use of inhibitory polymers by concurrently digesting and concentrating the mixed liquor in the digester.

Abstract: A phase separator, upflow reactor apparatuses and methods for separating phases are provided. The phase separator includes a first separation unit and a second separation unit, each of which has walls defining a coagulation area. One of the walls adjoins a deflector inclined to the horizontal and vertical. The separator also includes a plurality of parallel plates spaced from each other and vertically and horizontally inclined which each have a lower edge. The other wall of the separator adjoins one of the parallel plates and the deflector extends below and across the lower edges of the parallel plates. Each of the first and the second separation units is capable of separating a gas from a liquid by diverting the gas around one wall of each of the separation units and by creating a circulation of the liquid around at least one of the parallel plates such that liquid is directed into the coagulation area.
