Reduce biofilm formation

by LG Sonic     based in Zoetermeer, NETHERLANDS

In many industrial or professional applications where water is being stored, biofilm may grow. The growth of biofilm can damage the installations and reduce efficiency of the circuit. A biofilm can grow certain substrates which can be found in water. When temperatures are high, for example in cooling towers, a matrix of different micro- organisms such as bacteria, fungi, algae can grow very rapidly causing the formation of a biofilm on certain surfaces submerge in water. During the formation of this biofilm, certain micro organisms starts producing extra cellular polymeric substances (EPS) which reinforce the biofilm structure.

Cooling Tower, algae and biofilm control

by LG Sonic     based in Zoetermeer, NETHERLANDS

“Efficiently lowers algae, biofilm formation, bacterial counts and chemical consumption.” When temperatures are high, for example in cooling towers, a matrix of different microorganisms such as bacteria, fungi, EPS and algae can grow very rapidly. The disadvantages of biofilm formation in cooling towers can be enormous. Therefore water used in cooling towers needs frequent treatment and chemical shocks to keep levels of micro-organisms to a minimum.

Biowater’s technologies, such as our CFIC® process, can produce effluent water quality that is acceptable for re-use, reducing the stress on ecosystems in water stressed areas.

Microbial testing in cooling water system industry

by LuminUltra Technologies Ltd.     based in Fredericton, NEW BRUNSWICK (CANADA)

Superior reliability for superior control! Biocide treatments are essential to control microbiological growth in cooling systems. If not properly managed, the warm environments of cooling systems are ideal for the growth of microorganisms. As microorganism communities grow in cooling systems, they can attach to pipe walls and form biofilms. These biofilms pose serious risks, from human health risks like Legionnaire`s disease to reduced operating efficiency and eventually to equipment failure via microbiologically influenced corrosion (MIC).

Water treatment for legionella prevention and control

by Applied Oxidation LLC     based in Chattanooga, TENNESSEE (USA)

Whether you find yourself in a hotel bath room, cruise ship cabin, hospital, office building, industrial plant, greenhouse, car wash facility or your own hot tub, the combination of certain temperature levels, stagnant water and the presence of biofilm in water systems is a potential recipe for disaster: an outbreak of Legionnaires’ disease. An outbreak of Legionnaires’ disease is often the result of negligence, having legal repercussions for responsible parties. Because of its chemical and biocidal characteristics, chlorine dioxide is ideal for maintaining good standards of water hygiene. Chlorine dioxide has consistently been demonstrating to be the best molecule for eradicating the causative organism of Legionnaires’ disease.

Water treatment for cooling towers

by Applied Oxidation LLC     based in Chattanooga, TENNESSEE (USA)

Controlling and preventing the growth of microorganisms in a cooling tower is extremely important and required to keep the system running at optimal levels. The presence of microorganisms will cause the system to breakdown and decreases the efficiency of the heat transfer. Typically oxidizing biocides such as chlorine and bromine have been used to treat cooling water. Unfortunately these chemicals are highly reactive with other chemicals and microbiological species found in the water. Chlorine dioxide however is very non-reactive to other compounds found in the water and retains biocidal efficacy. Likewise it is also a superior chemical for removing the biofilm, which leads to the most predominant problems that all cooling towers face.

Monitoring of Algal Production / Monitoring of Algae Growth

by Chelsea Technologies Group     based in West Molesey, UNITED KINGDOM

Over the past 20 years active fluorescence has been widely adopted by the scientific community, ecosystem managers and crop growers as a rapid and non-invasive method of estimating photosynthetic performance within a wide range of organisms, including phytoplankton (microalgae and cyanobacteria), biofilms, benthic autotrophs (corals, macroalgae and sea grasses) and terrestrial plants. The main rational for applying active fluorescence is that changes in key fluorescence parameters can reveal the early onset of chronic and acute degradation of photosynthetic performance and subsequent growth, e.g. resulting from nutrient deficiency or the presence on one or more toxicants.

Over the past 15 years we have been developing an active fluorescence technique called Fast Repetition Rate (FRR) fluorometry to monitor algae populations in the open-ocean, primarily to support climate and ocean modelling.

Force Main Systems Sulfide Odor Control with Hydrogen Peroxide

by USP Technologies     based in Atlanta, GEORGIA (US) (USA)

Force main systems are typically high sulfide odor generators due to septicity conditions related to full pipe flow and a greater anaerobic slime layer (biofilm) thickness. Primary factors that influence sulfide loading generation in a force main include sewage temperature, BOD, retention time, pipe size and flow. Gaseous hydrogen sulfide (H2S) release at the force main discharge is usually the main concern related to odor and corrosion control needs; however, corrosion problems within the pipe can be of a concern (e.g. "crown cutting") at locations where air pockets can lead to concentrated H2S gas build up. Some basic considerations for assessing an appropriate sulfide odor treatment method for force main systems include: Retention time / duration of control Pump station type / cycling (e.g. vfd; start/stop, etc). Force main injection tap points, if any (e.g. air relief valves) Existence of intermediate re-lift stations or in series pump stations Manifold force main systems

DOCUPAK LLC REDUCES COOLING TOWER CHEMICAL USAGE BY A THIRD

by Scalewatcher North America Inc.     based in Oxford, PENNSYLVANIA (USA)

Docupak LLC, a full service marketing company headquartered in Alabaster, Alabama, has reduced chemical usage by a third and removed all scale from its cooling tower at its plant after installing the patented, award-winning Scalewatcher computerized, electronic water-conditioner from Scalewatcher North America. In addition there are no longer signs of algae growth on the cooling tower louvres. Founded in 1998, Docupak, the operating name of Document and Packaging Brokers Inc., develops and distributes materials for businesses nationwide. In addition to its headquarters in Alabaster, Alabama, the company also operates a further plant in Alexandria, VA and has sales offices in Atlanta, Chicago, Cincinnati, Dallas, Los Angeles, Tampa and Washington, D.C. Aware that health agencies continually draw attention to the risks of limescale and algae in cooling towers and wanting to reduce the use of chemicals in the cooling tower, Plant Manager, Anthony Kinstley decided to install the Scalewatcher electornic water-conditioner through local dealer, Al Chatham of Water Processing and Well Supply in Harpersville, Alabama. An industrial Scalewatcher was installed on to the water-feed line to the building and then a further unit was specifically fitted on to the recirculation line of the cooling tower. “Since using the system the scaling on our cooling tower has been eliminated and we currently use only a third of the original chemicals intended for the water treatment within our system”, said Anthony Kinstley. Many air conditioning and refrigeration plant systems are water-cooled. The heat generated by cooling coils is removed by water, which is passed through a water-cooling tower. These are recirculating systems, which operate at temperatures ideal for bacterial and algae growth, and have plentiful supplies of nutrients. In cooling towers, temperature, water hardness, pH, scale and corrosion are all factors, which increase the chance of biofilms, algae and Legionella colonization. The environmentally friendly Scalewatcher provides a permanent solution to hard water problems without the need of chemicals, salt or maintenance. It works by producing a varying electronically applied force field, induced by a coil wrapped around the outside of the pipework, which keeps the minerals in suspension and thus prevents limescale forming. The water’s increased solubility enables it to dissolve existing scale, which is gradually washed away. “Scalewatcher has proven itself to be highly effective. I would highly recommend this product and service without limitation,” concluded Antony Kinstley. Scalewatcher models are based on continuous research and over 25 years experience and expertise as market leaders in electronic scale control with countless units sold worldwide. The patented Scalewatcher systems are capable of treating pipe sizes from one to 120 inches. All Scalewatcher systems come with a full performance guarantee and are shipped throughout North America.
