Abstract:

The urgency of water crisis has attracted more and more research in the field of process systems engineering. Starting from describing the status of water crisis globally and in China, this paper introduces water crisis related policies from government and opinions from academic circles. Documentation retrieval for water network and virtual water studies since 1994 is conducted. The topic is systematically reviewed in three levels according to the scale size. ① Water network integration and optimization in a single enterprise, including water using network (WUN), wastewater treatment network (WWTN), total water network (TWN), complete water network (CWN), and three special problems, which are cooling water systems, WUN with internal water mains, water network for batch processes. Water allocation and heat exchange network (WAHEN) problems and simultaneous process synthesis with heat and water integrations are also included. ② Inter-plant multiple water network integration, including water networks integration in eco-industrial parks. ③ Virtual water and water footprints studies across prefectures/countries. These studies are very useful in water conservation, wastewater reduction, energy efficiency improvement in enterprises and eco-industrial parks, and also provide the basis for policy arrangements for governments particularly those of water scarce areas.

Key words: water network, process systems integration and optimization, water conservation and wastewater reduction, simultaneously optimization of water and energy, eco-industrial park, virtual water, water footprint
