An automated apparatus for introducing a mixed liquid base (lime) in a first container or tank (106, 106A) into a biological sludge in a second container (110, 110A and 110B) is described. The second container is used to house the sludge for a short period of time (2 to 12 hours) and then the liquid sludge is sent to a storage tank (112) for a longer period of time (6 months). The system (100) enables flushing of the lime supply conduits (108, 108A and 108B) with water to prevent clogging. The treated sludge is applied to soil as a fertilizer.
