Ozone in Cooling Water Treatment

When commercial ozone generators were first introduced for cooling water treatment, they were marketed as a stand-alone treatment, a cure-all or panacea. We now know this is not the case. Because there have been many misconceptions regarding ozone, this article is intended to review the basics of ozone, its true capabilities and limitations, and its potential benefits in cooling water treatment ...

Sanitation Using Ozone & Chlorine

For nearly 100 years, ozone has been used all over the world for water sanitation. It is nature’s strongest oxidizer and has a byproduct of pure oxygen. Chlorine, on the other hand, is a very effective, time-proven chemical, but is ineffective against hard-to-kill microorganisms such as cryptosporidium. It also has some unpleasant byproducts. Together, however, these two substances can ...

Ozone treatment for cooling towers

Abstract The use of ozone as a maintenance treatment for cooling towers has good potential for operation and maintenance savings in the Federal secior. A small amount of ozone acts as a powerful biocide thai decreases or nearly eliminates the need to remove quantities of water from the cooling tower in order to decrease the concentration of organic and mineral solids in the system. ...

Ozone for Waste water Treatment

Ozone has been used for many years to treat pathogens such as bacteria and algae in water for applications such as drinking water supplies and air conditioning system cooling water. More recently, most water bottlers have adopted ozone. Ozonated water for treatment of fruit, vegetables, fish, etc. in the U.S. awaited the GRAS approval. Now that has happened, and projects are emerging everywhere. ...

A study on the effects of ozone dosage on dissolved-ozone flotation (DOF) process performance

Dissolved-ozone flotation (DOF) is a tertiary wastewater treatment process, which combines ozonation and flotation. In this paper, a pilot-scale DOF system fed by secondary effluent from a wastewater treatment plant (WWTP) in China was used to study the effect of ozone dosage on the DOF process performance. The results show that an ozone dosage could affect the DOF performance to a large extent ...

Using Ozone Disinfection for EDC Removal

Clark County Water Reclamation District (CCWRD) serves the suburban area in and around the city of Las Vegas. The Las Vegas Valley is served by three treatment plants, which all discharge to the Las Vegas Wash. The wash empties into the Las Vegas Bay of Lake Mead. Lake Mead is also the source of drinking water for the Las Vegas Valley. In 1996 USGS reported symptoms of estrogen exposure in carp ...

Ozone-based reclamation of an STP effluent

The system ozone and hydrogen peroxide was used to reclaim wastewater from the secondary clarifier from a Sewage Treatment Plant (STP) of Alcalá de Henares (Madrid-Spain). The assays were performed by bubbling a gas mixture of oxygen and ozone, with ~24 g Nm-3 of ozone concentration, through a volume of wastewater samples for 20 minutes at 25°C . The removal of dissolved ...
