The Role of Ozone in Water Bottling
Water Quality Products
October 2003
L. Joseph Bollyky, Ph.D., P.E., Bollyky Associates, Inc. and Brian Johnson, Pacific Ozone Technology
Because of the relative and perceived ease of ozone treatment, many bottlers still don't use proven ozone process controls and monitoring technology. Thus, they're yet to assure precise ozone treatment, which is necessary when certain contaminants--such as bromide, from which bromate is formed--are present in the source water. The careful use of controls can result in bottled water of a higher quality.

The O-Zone: Today's Lesson: Ozonation of Cooling Towers
Water Quality Products
June 2003
Roger Nathanson
The objective of ozone use with cooling towers is to maintain the highest purity of water with the least amount of water waste and chemical use. Chemical use in cooling towers leads to ever-increasing total dissolved solids (TDS), which must be reduced by eliminating water (blow down/bleed off) and then refilling with raw/lower TDS water. This is a vicious circle that will never end unless one of the TDS-increasing culprits (a.k.a. chemicals) is eliminated or reduced.

Developments in Ozone Technology
Water Quality Products
July 2002
Rip G. Rice, Ph.D., RICE International Consulting Enterprises
Ozone technology developments have opened new applications for these established water treatment technologies. Driving these changes has been the identification of new, more disinfection-resistant microorganisms such as Giardia and Cryptosporidium cysts and governmental regulations designed to protect the public health from the hazards of ingestion of these microorganisms. Additionally, the desire to prevent or minimize the formation of halogenated disinfection byproducts formed during chlorination has stimulated new interest in the use of ozone. Combinations of ozone with hydrogen peroxide and/or ultraviolet (UV) radiation can destroy many contaminants present in ground water.
