Electrolytic Ozone Generation And Its Application In Pure Water Systems

Over the years manufacturers have become increasingly aware of the importance of water purity and its effect on the quality of the final product. One of the largest problems that confronts pure water system operators is bacterial recontamination shortly after the water purification equipment. There are several recommended methods of either preventing or removing such contamination but most have ...

Self-Cleaning Filtration for Pretreatment of Membrane, UV and Ozone Water Treatment Systems

Recent field data has shown the effectiveness of automatic self-cleaning filters in removing suspended solids down to less than 3 microns in size without flocculents, pre-coats or granulated media. Pre-treatment of ozone systems is often needed to remove organic solids that would utilize high amounts of ozone during oxidation leaving little for complete disinfection. Selfcleaning screen filters ...

Quantification of Helicobacter pylori in the viable but nonculturable state by quantitative PCR in water disinfected with ozone

Helicobacter pylori is a Gram-negative spiral-shaped bacterium that colonizes the gastric mucosa and is associated with gastric diseases. It may present a morphological adaptation when it is out of its natural environment, such as in water. The morphological adaptation is a coccoid form, which is a viable but non-culturable state (VNC) in which the DNA remains active and therefore infective. ...

A comparison of the Eulerian and particle tracking approaches for prediction of ozone contactor performance

The Eulerian and particle tracking approaches, two commonly utilized numerical methods, were evaluated for modelling drinking water ozone disinfection systems. The Eulerian approach predicts disinfection performance by solving an advection-diffusion equation. Alternatively, the particle tracking (Lagrangian) approach calculates disinfection efficiency by numerically introducing particles into the ...

The Use of Ozone in Cooling Towers

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 ...

Introducing ozone to water purification – Case Study

Traditionally, chlorine has been used to disinfect water for drinking. Unfortunately, chlorine produces carcinogenic by-products called trihalomethanes (THM’s) when it reacts with organic substances in surface waters. The recent adoption of the Surface Treatment Rules by the U.S. E.P.A. places strict limits on chlorine. Because ozone produces fewer disinfecting by-products, the EPA, along ...
