ABSTRACT:
Odors can arise from an enclosed waste processing system designed to convert solid waste into an aqueous pulp and extract a solid phase and an aqueous phase from the waste. The odors are the result of anaerobic portions of the system in which anaerobic microorganisms convert waste including fatty soils into volatile odor components including low molecular weight carboxylic acids. The action of these microorganisms can be controlled by maintaining the pH, of the aqueous phase common to all portions of the system, at above a pre-selected alkaline pH. Such a pH can be maintained by dosing the aqueous phase in the system with an appropriate amount of one or more alkalinity sources on a timely basis.
