1 STATE-OF-THE-ART FOR WATER NETWORK DESIGN USING GRAPHICAL VISUALISATION TOOL

Water is one of the most important resources for mankind. Over the years, the price of quality raw water has steadily increased due to increased demand and rising costs of water treatment. As a result, various water conservation strategies including water recovery, reduction, elimination, outsourcing and regeneration have been implemented world wide. Water pinch analysis is among the well established tools for water conservation which involves targeting and design of maximum water recovery network using graphical, algebraic or mathematical approaches. Each method has its own advantages and disadvantages. This work presents the state-of-the-art for the design of optimal water networks using graphical composite curves. The graphical visualisation tool offers valuable insights for practitioners to explore various water network targeting and design possibilities. The proposed tool is capable of handling global water-using operations
