Industries that produce most products use water in some stages of the production process. Strong industrial reliance on water makes it important to preserve water and ensure that water pollution reduced. Industry is reliant on water for all levels of production as it is often used as a raw material, solvent, coolant, transport agent, and energy source. Water is a necessity for all industrial production hence water must be protected, conserved, and used in a proper manner. For most industrial purposes, the water used needs to be freshwater and not saltwater as the salt content can corrode metal parts of the plant. Therefore, treated water is essential for industrial productions.
