On May 4-5th, the International Ozone Association (IOA) in conjunction with teh International UV Associations (IUVA)will hold their joint regional conference and exhibition at the Hyatt Regency Hotel in Cambridge, MA

The conference will provide technical presentations to scientists and engineers interested in the use of ozone or UV technologies.  Applications will include municipal drinking water treatment, wastewater treatment, food and beverage processing, and water reuse. 

The IOA and the IUVA are calling for papers for this conference.  Abstracts can be sent to abstracts@io3a.org by December 1, 2008.

for more information on this conference contact Diana Schoenberg at 480-544-0105 or dianas@io3a.org.

This conference, held every two years, draws hundreds of participants and papers and is the largest conference covering ozone and UV technologies in the Americas.  if you are interested in learning more about ozone or UV technologies for water treatment applications, this is the conference you should attend.

Ozone has long been considered an effective biocide in both liquid and gas phases.   New research suggests ozone in the gas phase may be able to keep produce such as lettuce free from pathogens.

Research on E. coli transmission showed ozone gas is faster and more effective than chlorinated water at sanitizing leafy greens.  Researchers  say it could be fed into lettuce storage areas operating under cooling vacuums.

The results of the research study were presented at a conference  atteneded by 300 food industry executives, growers and regulators in Monterey, CA. t

The research was funded by Fresh Express after the 2006 E. coli outbreak in spinach that resulted in the deaths three people. and sickened many more.  While Fresh Express was not linked to the 2006 spinach incident, the company funded the researxch as a way to prevent a future outbreak.

Ozone gas is currently used in a wide variety of applications, most prominently drinking water treatment where nearly 30% of the public drinking water systems use ozone in one way or another.  Ozone is also widely used in the food an beverage industry for various sanitizing applications.

Unlike most other biocides ozone is produced on site and eliminates the need to purchase, store or transport chemicals.  The feed source can be air and it is produced in an ozone generator.

Spartan Environmental Technologies supplies a variety of ozone based systems including ozone generators.

Ozone drinking water treatment is an important part of water quality protection in the US.  The chart above shows the growth in the use of ozone for treating drinking water in the US.  Overall 270 million Americans are served by public water systems.  On average, Americans use about 150 gallons per day per person of water.  This means that the public water works are producing in total about 40 billion gallons of water per day. 

The chart shows that about 30% of this total, or 12 billion gallons per day, is treated with ozone.  Over 240 plants employ ozone drinking water treatment.  Ozone generator capacity for all of those plants is around 450,000 lbs of ozone, nearly 1,900 lbs/installation. 

What is all of this ozone being used for?  There are numerous applications for ozone water treatment for potable water.  These include taste and odor control, color removal, filtration enhancement, disinfection and removal of toxic chemicals in the water such as those formed from the reaction of chlorine with organic compounds.  Most drinking water plants take advantage of more than one of ozone’s capabilities, essentially getting a 2 for 1 or 3 for 1 benefit for every dollar spent on the ozone generators.

Spartan Environmental Technologies supplies ozone generators and associated equipment for drinking water treatment.   You can contact us at 800-492-1252 or info@spartanwatertreatment.com.
