Industrial water recovery is commonly accepted as a promising mean to the water scarcity problem faced by the world-wide community. However, many regard that water recovery can only be achieved by the installation of purification units (e.g. filter) at the effluent discharge point of the wastewater treatment tank. This is indeed not true, as there are always direct reuse and recycle opportunities to be explored prior to the use of purification units, provided that appropriate mixing and segregation rules are followed.
Water pinch analysis technique has been widely accepted as a systematic design tool in synthesizing a water recovery network for maximum efficiency. It establishes the minimum fresh water and wastewater flowrates needed for a process plant after maximizing the reuse/recycle potential of its water sources, base on first principle (termed as targeting). After the water flowrate targets are established, some design rules are used to synthesize a network that achieves maximum water recovery.
