ENPAR successfully completes on-site testing of its pilot ammonia treatment plant

    TORONTO, May 27 /CNW/ - Dr. Gene Shelp, President and CEO of ENPAR
Technologies Inc. (TSX:ENP), ("ENPAR") is pleased to report that ENPAR has
completed the testing of the pilot scale ammonia treatment plant at a mine
site in northern Ontario.
    The testing program clearly demonstrated that the Company's patented
AmmEL-LC Water Treatment System effectively removes ammonia from mining waste
water to below the discharge requirement of 10 mg/L at a low operating cost of
approximately $0.10 per m(3) water treated. Furthermore, the efficiency of the
technology is not affected by low water temperature. The latter point is very
important because many mining sites occur in regions of the world where
temperatures are below 5 oC for several months of the year.
    The Company is currently utilizing the pilot scale test data to complete
the engineering design and assessment of related costs with the intent of
submitting a cost proposal to the mining company for a full-scale treatment
plant. As previously reported, ENPAR anticipates a commercial contract for the
construction and installation of the plant as part of the planned development
at the mining site.
    The mining industry represents an attractive market opportunity since
commercial blasting agents containing from 70-94% (by weight) ammonium nitrate
are extensively used. Leaching of the undetonated portions of the blasting
agents often result in elevated levels of ammonia and nitrate levels in mine
effluents. Mining companies continue to seek innovative approaches to assist
in managing ammonia in waste water.
    Ammonia also enters water from municipal waste water treatment
facilities, fertilizer runoff, leaching septic tanks, land application of
biosolids and raw sewage, and numerous industrial processes. This ammonia
water can be detrimental to fish and lead to eutrophication of water bodies.
Thus, the AmmEL technology represents a promising avenue to profitability and
maximizing shareholder value.
