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 cooling tower treatment with and without mineral removal

Abstract This paper builds on a prior paper by this author, McGrane (1991), In that paper, ozone is used as the sole means of cooling tower water treatment. The paper discusses water conservation by increased cycles of concentration, greatly increased efficiency through extremely low biological populations, and corrosion data which is compared to ozonated and chemically treated towers. ...

Cooling tower legionella pneumophila study CDC

Abstract Since the late 1970s, there have been many small and large outbreaks of Legionnaires’ disease. Most of these outbreaks have been traced to either cooling tower water systems or potable water systems. Although the bacteria most often associated with Legionnair’s disease, Legionella pneumophila, is present in many waater systems, outbreaks are usually a result of ...

Ozone systems for beginners

This paper is intended for people who know a cooling tower when they see one but have little or no knowledge of their care or what part ozone plays. I have tried to make this as simple as possible and there is even a block diagram on the last page to help you out. Ready? Okay, here is what you need to know first: The sole function of ozone use in evaporative cooling towers is to disinfect water. ...

Application of an environmentally optimum cooling water system design in water and energy conservation

Recirculating cooling water systems are consist of a cooling tower and heat-exchanger network which conventionally have a parallel configuration. However, reuse of water between different cooling duties enables cooling water networks to be designed with series arrangements. This will results in performance improvement and increased cooling tower capacity. Research on recirculating cooling water ...

Do You Need a Raw Water Treatment System for Your Plant?

Determining whether or not you need a raw water treatment system for your industrial facility can be a difficult decision. But if your plant draws from a raw water source (such as a river, lake, ocean, or groundwater), chances are you will need some sort of treatment. If left untreated, what is present in your water source can cause a variety of issues, such as contamination in drinking water ...
