The rise in world population and industrialization in developing nations has tremendously increased the demand for water and has resulted in wastewater contaminated with several pollutants. Thus, wastewater treatment, reuse, and safe disposal have become crucial for sustainable existence. Systematic guidelines which propose treatment based on inlet contamination and final desired conditions for water reuse and safe disposal can aid in designing efficient wastewater treatment and management systems. The treatment methods must vary based on the properties of the wastewater stream entering a treatment plant, such as: number of contaminants, their amounts, toxicity, shape, size, etc. To this end, a superstructure comprising of all possible treatment methods and an optimization strategy that eliminates certain technology options based on cost, and specific physical constraints, will make the generation of wastewater treatment networks more efficient. The technologies involved in wastewater treatment such as sedimentation, filtration, membranes, disinfection, adsorption, and activated sludge are modeled using the material and energy balance, equipment design, costing as well as environmental impact, which is in the form of linear and non-linear mathematical models. After model generation, the individual models are combined into the superstructure to create an optimization model where the technology selection is represented by integer constraints. The overall wastewater treatment process is optimized for cost using mixed integer non-linear programming (MINLP) solvers in GAMS (General Algebraic Modeling Systems).

This talk will help in understanding the following topics:

  • Technologies available for wastewater treatment
  • Superstructure generation
  • Mathematical formulation of simultaneous technology selection and cost minimization
  • MINLP optimization problems and solution methods
  • Capabilities of GAMS in solving large scale problems
