Description:
The Phase I objective is to demonstrate the disinfection capability of a new lamp and estimate commercial cost. Disinfection testing will be conducted in collaboration with a major manufacturer of ultraviolet (UV) disinfection equipment and will include comparison testing with commercial systems. A successful Phase I will lead to a prototype in Phase II and subsequent commercialization for use in UV disinfection. The change in regulations for drinking water treatment is leading to alternatives to chlorine for disinfection. As a result, the use of UV light for disinfection is growing rapidly. The disinfection capability of commercial UV systems is determined by available mercury lamp technology. Phoenix Science & Technology has developed a new UV lamp with the potential to increase disinfection dosage by a factor of 2.8 with the same electrical power. Because electricity is the largest cost of disinfection, use of the new lamp will reduce cost.Journal Articles:
