Ozone has been successfully applied to industrial cooling water systems with the resultant improvement in operational efficiency due to increased heat transfer, reduced system corrosion, improved environmental impact and reducedon-going chemical expenditure. The aim of this paper is to provide practical advice on the options available for the application of ozone and the potential benefits which ...
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. ...
Comparison of electrolytic oxidation v. ozone as biocide and reducing rate of TDS build-up in Cooling Tower Blow Down Water. Performed by Pureflow PtY Ltd of Singapore at Singapore Polytechnic Institute. Open evaporative cooling systems have been widely used throughout industry to remove heat from process systems and modern buildings for the purpose of air conditioning. As a result, due to this ...
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. ...

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 ...
This paper presents the operating results of ozone treatment of the water in a cooling system with an open loop containing the following elements: • Main cooling water pumps• Cooling water storage tanks• Distribution manifold to cooling water users• Cooling water collecting basins• Cooling water recycling pumps• Cooling tower The system reviewed in this paper is the side stream ...

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. ...
Ozonia Switzerland and a water treatment company have successfullyinstalled and commissioned a turnkey, fully assembled, containerised ozone system in a large Thermal Power Station. The ozone produced by the plant will be used to treat the raw make-up water being fed to the cooling towers and to compliment the proprietary biocide dosing program being used in the cooling system at the ...
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 ...
E.ON Benelux NV has replaced its existing ozone generators with Primozone® Ozone Generators for treatment of recirculating water in cooling towers at one of its power stations in Rotterdam, Holland. E.ON, one of the largest energy providers in Europe, have been using ozone for treating their cooling tower water for a decade. At its RoCa Power station in Rotterdam, Holland the existing ozone ...

The green movement has put environmental issues, such as clean energy and global warming, front and center on the world stage as the biggest names in finance, like Warren Buffet and ...
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 ...
Background and Company Performance Industry Challenges Tertiary and advanced wastewater treatment (WWT) is one of three stages in the cleaning of wastewater generated by the municipal and industrial sectors. Building on and improving upon the results of treatment through initial primary and secondary WWT stages alone, tertiary treatment is performed prior to waste ...
Situation: In January of 2000, Zentox Corporation replaced the existing ozone treatment system on the Vehicle Assembly Building (VAB) and Launch Control Center (LCC) cooling towers with a state-of-the-art ozone water treatment system that is centered on the Clean Streams™ Ozone Transfer Process. The cooling towers, a launch critical system located adjacent to the VAB, had been on ozone ...
Situation In May of 1997, Zentox Corporation replaced a traditional chemical treatment program at the Northern Virginia Community College Manassas campus with an ozone water treatment system centered on the Clean Streams™ Ozone Transfer Process. Two 220-ton BAC cooling towers were installed as part of a renovation of the chiller plant and condenser water system. The campus has two ...
