Ultra Guard Excels at WEFTEC '99.

VANCOUVER, British Columbia--(BUSINESS WIRE)--Oct. 22, 1999--

Service Systems International Ltd.'s (OTCBB:SVSY) subsidiary, UV Systems Technology Inc, exhibited at one of the world's premier Technology expositions and forums, WEFTEC `99. WEF is instrumental in facilitating communication and keeping its members up-to-date with developments in the field of wastewater treatment. This organization brings together 27 member associations from around the world in addition to those in the US & Canada for a total membership of 40,000. New Orleans set a new record in the number of exhibitors renting floor space with over 800 companies exhibiting. Almost half of its membership (17,511) attended this year's event. Apart from showcasing equipment, this conference is a forum for exchange of information through technical papers and meetings in the areas of evolving environmental legislation & guidelines, case studies of existing systems with field data, new technologies, and research into new treatment methods. It brings consumers together with providers. Those who evaluate, work with and have a need for technology such as, researchers & consultants, governmental agencies, and utility operators/owners, come together with technology owners/equipment manufacturers, service providers and interested public.

Ultra Guard(TM)'s unique ability to disinfect waste with significantly fewer lamps than alternative UV systems whether conventional low-pressure low-intensity, low pressure high-intensity or medium-pressure high-intensity alternatives was referenced in the technical paper presented by Dr. Karl Scheible, HydroQual Inc:

"ALTERNATIVE UV DISINFECTION TECHNOLOGY DEMONSTRATION STUDY ON

LOW-GRADE WASTEWATERS AT THE ROCKLAND COUNTY SEWER DISTRICT

(RCSD) NO.1 WWTP".

During the Presentation Dr. Scheible outlined the performance of the five systems tested as follows: "This shows the results of the design analysis for each of the configurations. The conventional system would require approximately 9200 lamps. About 380 quadritube (Ultra Guard(TM)) lamps would be needed, and about 1500 low-pressure, high-output lamps in the PCI unit. The low-pressure, high-output Elsag unit (bought by Trojan Technologies Inc.) would require 3800 lamps, while the medium-pressure unit needed 880 lamps." One of the significant findings of the Rockland study was that systems with a smaller spacing between the lamps performed significantly better than wider spaced systems in wastewaters with relatively high `solids loading'. Besides the higher germicidal per lamp output, Ultra Guard(TM)'s patented reactor chamber removes the `distance effect' that saps energy from other systems. It brings contaminants to the UV source through induced turbulence. Contaminants that are furthest away from the lamp are directed through design-induced hydraulics into intimate contact with the UV source rather than dissipating energy by traveling through a UV absorbing medium to get to a distant particle. In spite of the dramatically reduced number of lamps reported by the RCSD paper compared to others tested, it is a testament to the performance of an older version of the Ultra Guard(TM) System. The enhanced new design performed even better in Rosemere and Peterborough. Nonetheless, the paper speaks to advantages judged important in the specific application considered. It further confirms the determinations by LA County Sanitation District (reported at the Jointly sponsored Electrical Power Research Institute and U.S. Department of Energy `EPRI/DOE' conference, August 31, 1999), the Rosemere project and recently awarded world scale project in Peterborough, Ontario (CH2MHill/Gore & Storie Peterborough Engineering report).

WEFTEC also hosted a meeting of the Environmental Technology Verification (ETV) Committee to which Ultra Guard(TM) was invited. This committee is developing the testing protocol for evaluating technologies in wet weather applications such as Combined Sewer Overflow (CSO). The application of UV technology in this sector represents an area of acute need with vast potential. Given the numerous merits of Ultra Guard(TM) System and the award of the world's biggest pumping station/CSO project, Western Beaches - Toronto (September '99), the testing is welcomed as another opportunity to demonstrate the enhanced abilities of its latest full-scale demonstration unit (PDU). Ultra Guard(TM) Management sees this as another milestone on the road to increasing market capture. Its demonstrated ability to handle high particle loadings and to function effectively even in poor transmissivity fluids are definite assets for CSO application. Ultra Guard(TM) looks forward to confirming the findings of other projects through the EPA sponsored ETV program. Testing is expected to begin early in the New Year.

Given the growing project list, papers & reports related to Ultra Guard(TM)'s advantages at this and other conferences, the three-day event was marked with a flurry of visitors to Ultra Guard(TM)'s WEFTEC '99 booth. Staff fielded over 150 inquiries from interested parties. These varied from utilities looking for efficient disinfection technologies to companies that expressed an interest in representing Ultra Guard(TM). The company is presently responding to numerous proposal requests, negotiating with a number of candidate rep organizations and following-up with others that have the qualities required to maximize market share. These include organizations that have experience representing competing lines, as well as OEM manufacturers that provide turnkey treatment plants around the world.
