There is no question that the use of chlorine offers you a highly effective way to purify water and wastewater. The only question is: Which form of chlorine should you use?
An overview of UV disinfection and its applications.
An overview of an American Water Works Association Research Foundation project.
Membrane filtration, widely used in chemical and biotechnology processes, is already established as a valuable means of filtering and cleaning wastewater and industrial process water.
This paper summarizes ozonation and by-product formation chemistry as well as ways to control by-product formation.
In this article, some of the many reasons ozone would be chosen over other oxidants such as chlorine are discussed. If you have a reason to apply ozone as part of your water treatment project, you may be required to conduct a pilot study prior to installation of the equipment.

This paper evaluates the effectiveness of generating chlorine dioxide gas using Eka Chemical's method of sodium chlorate/hydrogen peroxide/sulfuric acid technology as it compares to the Rio Linda (Vulcan) chlorine gas/25 percent sodium chlorite system process at the El Paso Water Utilities' 40 mgd Canal (Umbenhauer/ Robertson) Water Plant in El Paso, Texas.
Is a new method of generating chlorine dioxide gas using sodium chlorate more effective than the typical sodium chlorite system?
ADM Milling Co./Nokomis Mill is a grain milling company that produces flour for regional bread manufacturers. Located in Minneapolis, ASM produces 10,000 cwt., or one million pounds of flour a day. Their use of chlorinated water results in the treatment of 1.2 to 3.5 gallons of water per minute.
ADM Milling relies on chlorinated water in the tempering process of grain milling production. In short, the tempering process cleans the wheat to rid it of dirt and debris, toughens the outer layer of the wheat kernal, and softens the inside - or the part ADM harvests and turns into flour.
In order to comply with more stringent government regulations, one plant converted from chlorine to ozone treatment.
