Biological control is critical to the prevention of waterborne disease and to the proper operation of equipment such as cooling towers, condensers, heat exchangers, water scrubbing systems, and reverse osmosis units. Inadequate control of fungus, algae and bacteria in such units can lead not only to illness (such as Legionnaire's disease) but also to fouling and corrosion, causing equipment failure, unscheduled downtime, reduced heat transfer efficiency and lost production. On the other hand, it may be appropriate to encourage microbial growth in a wastewater treatment system to ensure the health of beneficial microorganisms that remove certain kinds of organic matter. GE Water & Process Systems offers a range of products and treatments to eliminate or augment microorganism growth in water systems, including: Spectrus OX and NX oxidizing and non-oxidizing biocides BIOSCAN™ 2 ATP microbial monitoring system BioMate™ biocides for membrane systems BioPlus™ products to enhance microbial growth
