water microbiology Applications
Water is essential for life. It is part of the environment, being used in industrial processes and available as tap water. To secure the safety of water that is daily available, the amount of necessary microbiology tests to comply with regulatory requirements are increasing and are heavily relying on quick and accurate answers to confirm the identities of a broad selection of important micro-organisms.

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.
In 1985, the University of Surrey in collaboration with Oxfam developed the Oxfam DelAgua Portable Water Quality Monitoring Test Kit. The Oxfam DelAgua kit enables field workers to test water quality in remote and isolated situations and in circumstances where there is no access to a water testing laboratory. Since its development in 1985, the water test kit has been used by all the major International NGO-s and other aid agencies in over 130 countries around the world.
In 2006, The University of Surrey and other investors founded DelAgua Water Testing Limited to take over the management of the DelAgua organisation. Since then, various improvements have been made, including:
- The upgrading of all kits
- The upgrade of the design, manufacturing and distribution functions
- R&D to produce a portable microbiological testing kit that provides quantitative results in less than 20 minutes.
- The upgrade of existing services and the introduction of new services, including:
- Free access to a water quality risk assessment software program on DWT`s website
- Free access to a library of reference documents on DWT`s website
In addition to distributing its own kits and consumables, DWT also offers a distribution service for other manufacturers` products. The most popular products are detailed on this website, but those not detailed can also be supplied - DWT is able to source in excess of 60,000 products from numerous manufacturers.
DWT is committed to providing services and products to enable the provision of clean drinking water for everyone around the world.

A brewery process presents one of the biggest challenges possible to a microbiological control program. Microorganisms are responsible for both the production and the degradation of the product. Microbial control is also critical for production and filling equipment. A brewing environment offers various applications where chlorine dioxide may be employed, like as terminal sanitizing rinse in the CIP systems or sanitizer for pasteurizers or filler head assemblies.

Most food processing facilities currently use a combination of different chemicals for all surface and machine disinfection. They periodically rotate the use of different sanitizers to prevent the harmful microorganisms from building a resistance to their killing properties. Unfortunately facilities are still experiencing pathogen outbreaks. Chlorine dioxide’s unique killing ability does not allow for the build up of resistance or mutation, and therefore eliminates the need for all of the other chemicals. Chlorine dioxide is effective for use in controlling microbiological growth in flume waters and other food processing water systems such as chill water systems and hydrocoolers.
In recent years ozone laundry technology has proven itself to be an effective tool in helping to reduce water usage and energy consumption while also reducing wash and dry times, ensuring the absence of microorganisms, and improving the quality and useful life of laundered products. There are economic advantages to an ozone system as well as microbiological and environmental benefits. Currently in the United States there are over 2,000 ozone laundry systems in place and as many as 3,000 more in the United Kingdom alone.
