The TrojanUVPhox™ was designed to maximize efficiency - using 50%-90% less energy than other similarly sized UV reactors. Through the extensive use of computational fluid dynamics models and other computer simulation tools, it has been optically and hydraulically optimized to provide extremely efficient and cost-effective UV treatment. Its unique design allows for the use of multiple reactors in series.

Who Needs RED? An Empirical Method For Validating The Log-Inactivation Of A UV Reactor Thereby Eliminating The Need For RED And RED Bias UV reactors are traditionally validated by determining the Reduction Equivalent Dose (RED) that a reactor will achieve as a function of flow, UV transmittance (UVT), and lamp UV output under various operating conditions. RED is determined by relating the log-inactivation of a test microbe to a dose value using the UV dose-response curve of that microbe measured in the lab using a collimated beam apparatus. Because UV reactors deliver a dose distribution, the RED is dependent on the UV sensitivity of the organism being treated. By Keith G. Bircher Calgon Carbon Corporation

Case Study: Newport News Uses Emerson Ozone Instrumentation For Safe, Effective Disinfection Maintaining the quality of the water supply is the top priority for municipal drinking water treatment plants across the country. Water plants use several treatment processes to ensure water quality and safety, and these treatment steps include disinfection. Traditionally, chlorine is used in both primary and secondary disinfection treatments and has been used since 1908. Some water plants are moving to ozone for primary disinfection. One water utility that is taking this direction is Newport News Waterworks. Newport News Waterworks constructed a pilot plant that uses ozone in the primary disinfection process

ABOUT
WATER DISINFECTION
Water disinfection is the process of removing unwanted chemicals, biological contaminants, suspended solids and gases from contaminated water. It is also the elimination, deactivation or killing of pathogenic microorganisms.
Methods used include physical processes such as filtration, sedimentation, and distillation, biological processes such as slow sand filters or activated sludge, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.
Ozonators produce small quantities of ozone which is a strong oxidizing agent that kills pathogens over a short period of time.
Boiling:
In an emergency, boiling is the best way to disinfect water that is unsafe for drinking because it kills protozoan parasites, bacteria or viruses. Boiling however is energy intensive.
Distillation:
The water is usually boiled in a chamber making water to vaporize, and the pure steam leaves the non volatile contaminants behind. The steam is then condensed to form safe water. Just like boiling, distillation requires lots of resources to set up.
Reverse Osmosis (RO):
Water molecules are forced through a semi-permeable membrane, leaving the larger contaminants behind. Clean and safe water is collected from the "clean" side of the membrane leaving the contaminants behind
Water Filtration:
The contaminants are physically prevented from moving through the filter media which traps unwanted contaminants.
Ultra Violet Light:
Water passes through a clear chamber where it is exposed to Ultra Violet (UV) Light. UV light instantly destroys bacteria and viruses there by disinfecting water.
Water Softeners and deionizers:
Water passes through a media bed, usually sulfonated polystyrene beads. Deionization process gets rid of ions from water through ion exchange.
