Industrial water treatment is used to optimize most water-based industrial processes, such as: heating, cooling, processing, cleaning, and rinsing so that operating costs and risks are reduced. Poor water treatment lets water interact with the surfaces of pipes and vessels which contain it. Steam boilers can scale up or corrode, and these deposits will mean more fuel is needed to heat the same amount of water. Cooling towers can also scale up and corrode, but left untreated, the warm, dirty water they can contain will encourage bacteria to grow, and Legionnaires' Disease can be the fatal consequence. Also, water treatment is used to improve the quality of water contacting the manufactured product e.g. semiconductors, and/or can be part of the product e.g. beverages, pharmaceuticals, etc. In these instances, poor water treatment can cause defective products. Domestic water can become unsafe to drink if proper hygiene measures are neglected.


Advancements in water treatment technology have affected all areas of industrial water treatment.

Although mechanical filtration, such as reverse osmosis, is widely employed to filter contaminants,

other technologies including the use of ozone generators, wastewater evaporation, and bio remediation

are also able to address the challenges of industrial water treatment.Ozone treatment is a process in

which ozone gas is injected into waste streams as a means to reduce or eliminate the need for water

treatment chemicals or sanitizers that may be hazardous, including chlorine.
New water treatment technology and equipment now allow almost full reclaim, while eliminating costly disposal fees and hazardous waste.
