Estimation of wastewater treatment objectives through maximum entropy

Article Abstract:

The method of balancing objectives of cost minimization and pollution prevention is examined in publicly-owned wastewater treatment plants. Parameters in the objective of plants are studied as the basis for ranking its objectives while considering necessary trade-offs between cost and water quality. An estimated model of wastewater treatment is derived as a useful tool in gathering information for publicly-owned treatment plants and policy makers in searching for alternative wastewater management guidelines.
