  • BioSense a Biofilm Monitor and Controller

    Abstract Biofilms (slime) can form on virtually every nonshedding surface, in a nonsterile aqueous environment i.e. anywhere where a water source is present; such as cooling/heating systems, swimming areas and in drinking water purification. These Biofilms can cause a myriad of problems including; harbouring harmful bacteria such as Legionella, inducing corrosion, and reducing ...

  • Multifunctional magnetic nanoparticles for orthopedic and biofilm infections

    Bone related infectious diseases (including osteomyelitis and prosthesis infection) are of great concern to the medical world. These types of deep tissue infections involve biofilms and are frequently chronic and always painful. Biofilms are infections whereby bacteria form a robust colony protected by a sticky slime matrix from the body's immune system (or natural clearance) and are resistant to ...

  • Biofilm control strategies in industrial processing waters

    Bacterial biofilms cause a number of serious problems for industrial fluid processing operations. Mechanical blockages, impedance of heat transfer processes and microbially induced corrosion result in billions of dollars of losses each year. In engineered systems, such as cooling water systems, food processing, and other industrial applications possible risk to public health and product spoilage ...

  • Organic matter removal from saline agricultural drainage wastewater using a moving bed biofilm reactor

    We investigated the effect of salinity on the removal of organics and ammonium from agricultural drainage wastewater (ADW) using moving bed biofilm reactors (MBBRs). Under the typical salinity level of ADW (total dissolved solids (TDS) concentration up to 2.5 g·L−1), microorganisms were acclimated for 40 days on plastic carriers and a stable slime layer of attached biofilm was formed. Next, ...

  • Microbial control reduces sulfide

    The article is about sewage odour control using a totally NEW technology known as Microbial Control. Microbial control treats the cause of sewage odour, corrosion and methane gas production in sewers by removing the biofilm / sediment (slimes) complexes where sewage odour and methane gas are produced. Without sewage odour you cannot have sewage infrastructure corrosion from sulfuric acid. As ...

  • EPA Proposes Two Test Methods and Guidance for Evaluating Antimicrobial Pesticides

    The U.S. Environmental Protection Agency (EPA) has recently announced the availability of two proposed test methods and associated testing guidance for evaluating antimicrobial pesticides against two biofilm bacteria, Pseudomonas aeruginosa and Staphylococcus aureus, for comments.  EPA states that registrants of antimicrobial products with public health claims are “required to submit ...

  • Extended CSO control storage: what could possibly go wrong?

    The Thames Tideway Tunnel (TTT), is one of the main components of the London Tideway Improvements Programme, designed to capture combined sewer overflows (CSOs) which currently discharge untreated combined sewage into the tidal river Thames. CSO discharges would be stored in the tunnel until there is capacity at Beckton sewage treatment works (STW), to accept, for treatment, pumped sewage from ...

  • Future-oriented further developments: wastewater heat utilization plants with a return on investment (ROI) of 2 - 6 years

    Sewage is dirty and stinks. Out of sniffing distance – out of mind. Up until the 1980s sewage was taboo and not given the attention it deserves. One cold winter morning in 1988, 23 years ago, Urs Studer stopped beside a steaming manhole cover and wondered how such a source of heat could go untapped. Ever since he has been dedicating himself intensively to the recycling of sewage heat. At ...

  • Hospital cooling tower application

    The Challenge: One of the largest teaching hospitals in Illinois wanted to improve safety and “green” operations in their cooling tower water treatment chemical regimen without sacrificing effectiveness. The Solution: Replacement of bulk bleach with on-site generated MIOX® mixed oxidant solution, Earthwise reduced the hospital's liability from ...

  • Overcoming iron bacteria problems: An Australian perspective

    Iron bacteria are becoming an increasing problem in groundwater bores and are estimated to affect about 40% of the world’s water bores with anecdotal evidence indicating that this number is steadily increasing. Iron bacteria derive energy during their metabolism through oxidising soluble ferrous iron, present in the groundwater, to its insoluble ferric form. The resultant biofilm is ...

  • Legionella

    Nomenclature Legionnaires' disease a pneumonia caused by any serogroup or sub-group of Legionella pneumophila Legionella pneumonia a pneumonia caused by any species of Legionella Pontiac Fever an acute, self-limiting, “flu-like” illness caused by certain species of Legionella Legionellosis any human ...

  • Santa Cruz Meets THM/DBP Challenge with Unique Air Stripping Process - Case Study

    Summary Santa Cruz has successfully demonstrated an innovative way for the City to meet its water quality goals while using process recycled water as part of its supply source. Using the recycled water had caused concern about reliably meeting the U.S. EPA THM/DBP potable water quality standards in its finished water. The City evaluated various aeration treatment processes and chose an E-Z ...
