Enhanced nearest neighbors algorithm for design of water networks

▸ Nearest Neighbors Algorithm (NNA) was earlier applicable to fixed flowrate processes. ▸ Enhanced NNA extends to water networks with fixed contaminant-load (FC) processes. ▸ Priority is given to local-recycle (LR) match with maximized flowrate for FC process. ▸ LR match is later eliminated for FC process to give design with minimum network flow. ▸ Case studies show versatility of Enhanced NNA to yield superior practical designs.
