Major domestic petrochemical complexes are adopting modern water treatment approaches, including zero liquid discharge (ZLD) systems, to curb excessive water consumption.
Zero liquid discharge can be defined broadly as a process to achieve maximum water recovery from a wastewater source that would otherwise be disposed of.  This water is beneficially reused and the salts and other solids contained in the wastewater are discarded in a landfill.
According to Mohammad Ayazi, Research Institute of Petroleum Industry's director for development and optimization of Energy Technology Division, five petrochemical companies, namely Fajr, Maroun, Razi, Arvand and Ilam, have so far adopted the ZLD recycling system that has significantly reduced their water intake from nearby rivers, NIPNA reported.
