Abstract

PURPOSE: To always maintain sludge indexes to objective value regardless of quantitative and qualitative variations of inflow sewage by calculating the sludge indexes from measurable values of movements of materials in an anaerobic tank and a precipitation pond and by adjusting the removal of the sludge amount in response to the difference between the calculated value and objective value of the sludge indexes.
