ABSTRACT:
In a long vertical shaft bioreactor for the treatment of degradable wastes in a circulating loop, a process is provided for separating and treating the slowly biodegradable components of the waste. The process comprises the steps of aerating and oxidizing the waste liquor in the reactor to produce an effluent and a foam which foam contains the slowly biodegradable components, which have not been degraded in the oxidizing step, separating and collecting the foam, collapsing the foam and subjecting the collapsed foam to further aeration/oxidation treatment to produce a treated effluent. The thus further treated effluent is returned to the bioreactor for reprocessing.
