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. ...
The City of Phoenix is investigating the use of various disinfection technologies for its 91st Avenue wastewater treatment facility. Key to this investigation is the implementation of a UV system to meet State of Arizona, Class A+ disinfection requirements. During this evaluation, the range of alternatives was expanded to include ozonation and other advanced oxidation processes (AOP), to examine ...

The system is completely from European origin and will be delivered with a ...
Project Description: Lenntech has engineered, manufactured and assembled an ozone disinfection system in Malaysia. The ozonated water is used to disinfect recicrulated potable water on an oil rig in the South China sea. The generator produces 10 g/h of ozone. The Lenntech ozone system series are equipped with top brand instrumentation and equipment. The system is completely from European origin ...
Project Description: Lenntech has engineered, manufactured and assembled a membrane degassing system in the State of Libya. The degassed water is used to for oxygen removal prior to boiler feed. The Lenntech ozone system series are equipped with top brand instrumentation and equipment. The system is completely from European origin and will be delivered with a certificate of origin. Scope of ...
The European Biocidal Products Regulation (Regulation (EU) No. 528/2012) stipulates that biocidal products may only be made available and used on the market if they are certified in accordance with this regulation. Unlike the previous biocidal products legislation, so-called “in-situ” procedures such as electrolysis, chlorine dioxide and ozone now also fall under this certification ...
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 ...
US Environment Protection Agency (USEPA) regulations require mining operations to remediate their waste streams prior to environmental discharge. Wastewater streams from gold mine operations can be particularly toxic due to the potential for cyanide contamination and the concentration of metals contained in the wastewater effluent. This paper reviews the challenges and success of installing and ...
Abstract Ozone, like all oxidizing gases, is potentially harmful if human exposures occur at a significant concentration for a sufficient duration. This paper discusses the physical properties of ozone, current exposure standards, toxicology of ozone, and recommended safety practices for safe operations in cooiing water treatment ...
Growing operational costs and lower-than average occupancy rates spurred Apple Farm Inn and Suites, San Luis Obispo, Ca., to explore economic and facility-efficiency benefits obtained through the installation of an ozone laundry system. At the Apple Farm Inn laundry facility, an evaluation lasting several months was conducted in late 2006 into 2007, comparing the costs of laundering by ...
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 ...
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 ...
Novartis’ animal health manufacturing facility produces veterinary products for the UK and international market. Novartis committed to a £5 million investment in the site to ensure that it is a Centre of Excellence for the production of non-sterile liquid manufacturing within Novartis Animal Health. Puretch supplied a new purified water ozonated distribution system to the facility. ...
Historic activities at the site involved degreasing and industrial clean-ing service using solvents, primarily tetrachloroethene (PCE) and trichloroethene (TCE) to support the growing aerospace industry in Southern California. Site investigations indicated the presence of volatile organic compounds (VOCs), including. PCE, TCE, cis-1,2-dicloroethene (1,2-DCE), 1,1-dichloroethane (1,1-DCA), ...
The objective of this research was to include ozonation prior to an activated sludge treatment and investigate the effect on the nitrogen species, their fate and the consequences of this oxidation upon the biomass. Three parallel treatment systems were used: the base system, where feed went directly to the activated sludge reactor, and two others, where the influent was ozonated at two different ...
Abstract Ozone generating equipment was retrofit into the laundry washroom of the Gaston Memorial Hospital in Gastonia, NC, and began operating in the early part of July, 2010. Three ozone generating systems service six washer-extractors in the washroom. The performance of this fine-bubble ozone diffusion laundering system has been monitored since that time, with various adjustments made to ...
The removal of selected pharmaceuticals and personal care products, atrazine, and disinfection by-product precursors, was evaluated during a pilot-scale study conducted at the Bollman Water Treatment Plant in Concord, California, USA. Treatment alternatives included ozonation followed by biologically active filtration (BAF), and nanofiltration. Both technologies exhibited excellent broad-spectrum ...
The IE Oil Field Treatment System (OFTS) offers a portable, yet high-quality, answer for oil well operators seeking to treat produce water from their drilling operations. The OFTS utilizes the extraordinary separation and dewatering characteristics of the FloccinAgent™ line of products, coupled with IE’s technical expertise and experience in wastewater treatment, to quickly and efficiently remove ...
The first comprehensive study - bench-top laboratory investigations, pilot scale testing, and critical monitoring and evaluation of field applications - addressing the effects of ozone as a stand-alone cooling water treatment program is presented. The study also represents the first critical comparison of ozone-treated systems with non-treated systems. Excellent corrosion control can be attained ...
