A multiobjective optimization model for processing and distributing biosolids to reuse fields

摘要: Advanced wastewater treatment plants remove deleterious nutrients, chemicals, and microorganisms from produce biosolids products to be reused at farms other sites. These are carefully regulated by environmental restrictions but still may malodorous the local populations. In this paper, we develop a multiobjective optimization model simultaneously minimize odours as well processing distribution costs. The employs linear odour function bilinear costs; latter being approximated via Schur's decomposition special ordered set (SOS) type 2 variables resulting in mixed integer problem. Such can used proactively these least product minimal We demonstrate use of with case study for Blue Plains advanced plant run DC Water Sewer Authority Washington, DC.
