Incorporating Production Scheduling in the Optimal Operation of Wastewater Treatment Plants

摘要

The generation of wastewater is common to every industry, as a result of the production process. Whenever organic compounds must be removed, the most suitable treatment is through the activated sludge system. During the treatment, there is an increase in the mass of microorganisms, which needs to be removed. In multiproduct lants, production tasks affect the wastewater characteristics and therefore may have a significant impact on the sludge discharge. The purpose of this paper is to develop an optimization model to minimize the sludge discharge by incorporating scheduling decisions. Reductions of approximately 10percent are achieved with respect to the optimal dynamic operation of treatment plants.
