Cooling Tower, algae and biofilm control

“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.

Water treatment for cooling towers

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.

Water treatment for legionella prevention and control

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 hospitals

Horticultural and greenhouse operations are facing increasing challenges in dealing with sanitation issues related to water treatment. Over the course of growing a crop, pathogenic microorganisms accumulate and algae flourish on moist surfaces posing a constant threat to plants and produce. The main challenges lie the areas of irrigation water, elimination of biofilm and algae control. Existing biocidal products, while effective in killing algae, are not effective in removing biofilm from the water lines. The ultimate solution would be to employ a biocide that is capable to control algae on greenhouse surfaces and strip the biofilm in irrigation lines. Chlorine dioxide has demonstrated to possess both properties.

Irrigation Water Chlorine Dioxide Treatment

Irrigation Systems: A common problem encountered in all irrigation systems is growth of micro-organisms in the irrigation pipes causing poor flow, blockages and the potential for the spread of disease-causing organisms throughout the irrigated area, particularly fungal diseases. The micro-organisms flourishing in irrigation pipes include bacteria and fungi and, if sufficient light is present, algae. Irrigation pipes provide an ideal environment for the establishment of biofilm on the inside of the pipes.

Chlorine Dioxide Water Treatment for Power Plants

Chlorine dioxide is a significant product in the control of algae, planktonic and sessile bacteria, bio-film and scale in power plants, cooling towers, loops and cooling systems. CleanOxide helps maintain the efficiency of heat exchanger surfaces, reservoir intakes and ancillary equipment. Traditional oxidising agents such as chlorine and bromine, on the other hand, are associated with pH constraints and corrosion problems.

Force Main Systems Sulfide Odor Control with Hydrogen Peroxide

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

Biological wastewater processes for mining

The mining industry has the potential to use large amounts of wastewater in its operations. Often times these waste streams contain contaminants that require treatment before the water can be re-used or discharged. Biowater has successfully installed highly efficient biofilm treatment processes including our complete mix fixed film (CMFF®) system to remove BOD/COD, and nitrogen from mining waste streams. 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

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).

DOCUPAK LLC REDUCES COOLING TOWER CHEMICAL USAGE BY A THIRD

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.
