Abstract:
Biocidal activities of monochloramine and peracetic acid were studied on cysts of Naegleria lovaniensis. Until recently the most commonly used biocide to disinfect cooling water systems was hypochlorite. Owing to its negative impact on the aquatic environment, ecologically less harmful alternatives have been sought. As the biocidal activity of monochloramine and peracetic acid makes them good candidates for inactivation of pathogenic Naegleria species, these biocides were tested against Naegleria lovaniensis, a relative of the pathogen Naegleria fowleri, as an alternative treatment to hypochlo

Antimicrobial resistance is one of the greatest dangers to public health of the 21st century, threatening the treatment and prevention of infectious diseases globally.

In an era of antimicrobial resistance and emerging disease, the effective application of biocidal control measures is vital to protect public health.

There is a need to understand the importance of the mechanisms by which carbon (and hence COD) is removed from the wastewater.

Abstract The biocidal efficacy of halogenated hydantoins against laboratory-prepared biofilms was compared to the free halogen donors NaOCl and NaOBr. Higher biocide concentrations were required to control a filamentous biofilm than to control free floating planktonic bacteria. Control of a biocide-resistant S. natans biofilm was best obtained with a repeated slug+3 hour continuous treatment procedure or with conventional continuous biocide treatment. A bromine, methylethylhydantoin-containing oxidizing biocide (BrMEH) was found to be more efficacious than either free chlorine or free bromine

Abstract:
Abstract Cooling towers provide an ideal environment for the growth of Legionella pneumophila. Guidelines published by industry groups and governmental bodies recommend the use of oxidizing biocides for the control of L. pneumophila populations. We report here the results of a literature review on the biocidal activity of the oxidizing biocide bromochlorodimethyl-hydantoin (BCDMH) against L. pneumophila. BCDMH achieved &amp;gt;99.9% reduction in viability within 10 minutes of planktonic, pure culture L. pneumophila with 1 ppm free residual chlorine in a typical cooling water. Studies in dynami

Abstract:
Abstract Microbiologically Influenced Corrosion (MIC) may be a factor in 15–30% of failures due to corrosion in all industries. Chemical treatments for mitigating and controlling MIC processes represent significant cost and environmental liability. Because regulatory pressure on the use of toxic biocides is increasing, more environmentally acceptable control measures must be developed. To that end, laboratory experimental test-loops (TLs) were used to test more environmentally acceptable treatment chemicals. Produced waters from natural gas production and storage fields were recirculated throu

Abstract:
Antimicrobial resistance (AMR) is the resistance of a microorganism to an antimicrobial agent (a substance that kills or stops the growth of microorganisms) that was originally effective for treatment of infections caused by it. As a result standard antimicrobial drug treatments may become ineffective, lead to infections persisting, increasing the risk of spread to others, and negative clinical outcomes. AMR is a major public health issue worldwide and it is estimated that unless action is taken to tackle AMR, the global impact of AMR could be 10 million deaths annually from drug-resistant inf
