WEFTEC, the annual water quality technical conference and exhibition, promises an extensive slate of educational programs and an exhibition of companies displaying industrial water-related technologies and services.
Evoqua Water Technologies Corp. acquired privately held IsH20Top (pronounced “isotope”) Group, a Quebec-based provider of high-purity water treatment equipment and systems, equipment maintenance services and service deionization. The acquisition strengthens Evoqua’s Canadian service capabilities.
BioSpray Tower will disinfect hard, nonporous surfaces, says the manufacturer. The EPA-registered disinfectant kills 99.9 percent of Legionella pneumophila when correctly applied to hard, nonporous surfaces like cooling towers.
Model TD-550 is suitable for crude oils and other heavy oils. It offers a detection range of low ppb to 5000 ppm. Features include a large full-color touchscreen interface and advanced datalogging and graphing capabilities.
Is it time to reconsider testing for total bacteria and Legionella in cooling tower water? Two case histories demonstrate how current water-testing methods could be indicating that bacteria control is acceptable and under good control — when the opposite is true.
Microbiological testing, specifically for total bacteria and Legionella bacteria in cooling tower water systems, has been using a methodology that basically has not changed for many years. The recent Legionnaires’ disease outbreaks due to cooling tower water systems has prompted a closer look at the methodology to determine if there is a need to consider a change that would be more representative of the true microbiological levels in these systems.
A South Dakota industrial manufacturer was using both ozone and a nonoxidizing microbiocide to manage microbiological growth in its cooling water system. The solution, unfortunately, was not controlling fouling as anticipated, and this prevented the facility from achieving its operational goals.
The International Water Conference (IWC), designed for understanding and dealing with the technical and business challenges of the industrial water treatment, will be held November 4-8 at Talking Stick Resort in Scottsdale, Ariz. The IWC presents scientific advances and practical applications in water treatment and use, cutting across a range of industries, technologies and functional areas.
