FORT LAUDERDALE, FL, Oct. 5, 2004 (PRNewswire-FirstCall) -- Enviro Voraxial Technology Inc. has published a comprehensive report describing the impressive results from the company's VAS4000GS Voraxial® Grit Separator, which has been operating for the past eight months at the Northwest Regional Water Reclamation Facility in Tampa, Fla.

The report illustrates the Voraxial Grit Separator's superior performance over existing grit separation technology. It achieved an overall separation efficiency of 81% to 89% (by weight) of the entire range of grit particles sizes in the influent wastewater stream. For sugar sand particles (particles less than 150 microns in size), the product's efficiency exceeded existing standard equipment design by over 20%. This increase in separation performance translates into operating cost savings and increase plant efficiency for the wastewater industry by: 1) increased efficiency of the grit solids removal, 2) decreased pump and tank maintenance costs, 3) extended time period between tank cleanings, and 4) reduced solids loading in clarifiers and sludge handling facilities.

An additional benefit is its in-line piped arrangement. Since it can be installed as an in-line piped grit removal system; the capital cost of constructing concrete grit chamber tankage is unnecessary - resulting in a new grit separation system which reduces headworks construction costs approximately 30% according to Frank J. DeMicco, COO of EVTN. It can be easily and economically retrofitted into existing plants to handle any increase in volume or to improve grit separation efficiency.

Further, the in-line piped arrangement allows it to be utilized at pumping stations or lift stations to reduce the amount of sand and grit pumped to the wastewater facility. Current grit separation devices cannot economically address this issue.

"These results clearly demonstrate that the VAS4000GS Voraxial Grit Separator is a highly efficient grit removal device. The separator achieved excellent overall efficiency and the data shows that the separator can remove sugar sand and grit efficiently," said Dan Samela, PhD, PE.

About Enviro Voraxial Technology
Enviro Voraxial Technology Inc.'s patented VoraxialTM Separator is a cost-efficient, continuous flow separator that simultaneously separates liquid/liquid, liquid/solid or liquid/liquid/solid mixtures at extremely high flow rates while achieving very high levels of purity. Its technological superiority over conventional technologies is in its ability to produce a real-time, high "g" centrifugal force to yield a high-purity product or products at a volume of 3 gallons per minute to over 10,000 gallons per minute.

The Voraxial Separator technology is scaleable and nearly universal in its implementation. Although the technology is applicable to almost any industry separation process, the company is focusing its near-term efforts in the following four vertical markets: municipal wastewater industry, oil exploration and production, oil refineries, and manufacturing.

EVTN has begun the sales and marketing efforts in these markets with: 1) the installation of the Voraxial Grit Separator demonstration for the removal of sand and grit at Hillsborough County Wastewater Facility in Tampa, Florida, 2) unit delivery to an oil-service company that not only performs wastewater treatment for offshore oil production platforms, but also provides services for industrial applications, and 3) unit delivery to an environmental service company for liquid/liquid and liquid/solid separation at the refineries in Colorado and Wyoming.

EVTN is continuing to develop and market its Voraxial Separator as stand-alone technology as well as a key component to improve the efficiency of self-contained treatment systems for multiple applications.
