Abstract
An improved digestion process applicable to aerobic and anaerobic digesters is provided for waste treatment facilities during normal and overload conditions. The digestion system utilizes the addition of a lactobacillus fermentation product in a concentration sufficient to improve the digestion of units without deleteriously affecting the digestion system during normal load conditions. In addition, the use of the lactobacillus fermentation product facilitates recovery of digester systems from sour digestion conditions ('stuck digesters') in relatively short periods of time. Further, the ability of the digestion system to operate at higher-than-normal loadings and lower-than-normal detention times permits the use of existing facilities at not only peak periods which would otherwise be subjected to overloadings, but to be able to actually operate a system at twice designed loading, thus allowing for increased digester system capacity without incurring new capital equipment costs.
