Corrosion: What Is It and How to Control It

What is corrosion? Corrosion is the degradation or deterioration of a material caused by a reaction to its environment. In building plumbing systems, corrosion can occur in our piping systems and water-bearing equipment due to reactions, chemicals, and impurities in the water. These processes result in uniform corrosion, pitting, cracking, or erosion, ultimately causing the […]

The Biocide Chlorine Dioxide Stimulates Biofilm Formation in Bacillus subtilis by Activation of the Histidine Kinase KinC

MOSHE SHEMESH, ROBERTO KOLTER, RICHARD LOSICKAMERICAN SOCIETY FOR MICROBIOLOGY, JOURNAL OF BACTERIOLOGY, DECEMBER 2010 IntroductionThe goal of this study was to examine how biofilm formation is stimulated by chlorine dioxide, a chemical that is typically very effective and fast-acting against bacteria. The study examined how chlorine dioxide works and how the biofilm acts as a protector […]

Controlling Legionella in Hospital Drinking Water: An Evidence-Based Review of Disinfection Methods

YUSEN LIN, JANET E. STOUT, VICTOR YUCAMBRIDGE UNIVERSITY PRESS, INFECTION CONTROL AND HOSPITAL EPIDEMIOLOGY, FEBRUARY 2011 IntroductionThis study reviewed the efficacy of different disinfection methods for controlling Legionella in hospitals, including copper-silver ionization, chlorine dioxide, hyperchlorination, monochloramine, UV, point-of-use filtration, and superheat-and-flush. The four criteria each disinfection method must meet to validate efficacy include: ResultsA summary […]

PROIETTO, NAVNEET SAINI, PAOLA BORELLA, ANNALISA BARGELLINIAMERICAN SOCIETY FOR MICROBIOLOGY, APPLIED AND ENVIRONMENTAL BIOLOGY,  MAY 2016 IntroductionThis study evaluated four disinfection methods for their efficacy in controlling Legionella and their corrosive effects on water pipes. The four methods included: ResultsLegionella controlOf the four disinfection methods […]

Use of Copper-Silver Ionization for the Control of Legionella in Alkaline Environments at Healthcare Facilities

DAVID M. DZIEWULSKI, ERIN INGLES, NECULAI CODRU, JOHN STREPELIS, DIANNA SCHOONMAKER-BOPPELSEVIER, AMERICAN JOURNAL OF INFECTION CONTROL, JULY 2015 IntroductionThis study examined two healthcare facilities using copper-silver ionization to control Legionella in alkaline water conditions. One facility was an acute care facility with a pH range of 8.7-9.9. The other was a long-term care facility with a pH […]
