Unit for aerobic or anaerobic effluent fermentation - consists of standard rectangular modules and permits different process sequences

摘要

Appts. consists of rectangular modules erected from flat walls and partitions with structural beams, etc., the total height being at least 7 m, and is suitable for using a two-parameter aeration system. Partitions are provided with openings which permit operating different processes, i.e. batch flow, parallel flow, batch addition of effluent, batch addition of biomass, and alternating aeration. - For anaerobic treatment, the fermentation compartments are pref. provided with downwardly converging pyramid-shaped bottom hoppers, circulation and homogenising being produced by sludge pumps.
