Optimal design of Water Treatment Networks: effluent and piping disaggregated modelling

Water availability is of crucial importance to industry; therefore, optimal management of this resource has garnered increased importance. This work focuses on industrial water treatment networks (WTN) optimal design models, and can be divided in two sections. The first section addresses the modification of typical mathematical routines to implement efficient and rigorous effluent formulations, using an integer disaggregated formulation. The second section considers network piping expenditures, employing a two-step methodology to account for the discontinuous classes of commercialized piping.
