Sludge Watch ==> ENPAR - removing ammonia from sludge dewatering liquids

[maureen.reilly at sympatico.ca]

Sludgewatch Admin

Many sewage treatment plants release dangerous amounts of ammonia in their 
effluents.
The City of London Ontario comes to mind.

Canada has declared ammonia to be a critical Canadian Environmental 
Protection Act toxin
(CEPA list of toxins)   See: 
http://canadagazette.gc.ca/partII/2003/20030101/html/sor10-e.html

This is due to the dreadful damage ammonia does in the aquatic environment.
Sewage treatment plants must not be allowed to continue to pollute surface 
waters!

Canadian Wastewater Association (CWWA) is cranked that their sewage and 
sludge effluents are considered 'toxic'.  Ask the fish if its toxic.  CWWA 
complaints about being held to account for their massive toxic discharges is 
on their website.

Definition of Toxic: Of, relating to, or caused by a toxin or other poison: 
a toxic condition;
Capable of causing injury or death, especially by chemical means; poisonous:

CWWA  want the federal legislative language changed to something that sounds 
nicer than 'toxic'. 'Toxic' just sounds so ..um...nasty.   How about 
'substance that needs some management'...prettier isn't it?   Kinda like 
'biosolids'.... makes the mind go numb.

ENPAR is a technology that can remove ammonia from ammonia contaminated 
water before the water is discharged to the environment.  So the Canadian 
Wastewater Association (CWWA)  should stop whining and start shopping.

Company awarded United Kingdom patent for its ammonia treatment technology

    TORONTO, May 31 /CNW/ - ENPAR Technologies Inc. ("ENPAR" or "the
Company") is pleased to announce that it has received a patent for its AmmEL
System. Additional patents for the technology in Canada, the European Union
and the United States are anticipated within the near future.

    The current patent is for improvements made to the Company's US and
Canadian patents that were awarded on July 4, 2000 and December, 2005,
respectively. The improvements broaden the applications of the technology,
which now include treatment of solutions resulting from dewatering of sludge
or bio-solids and containing extremely high levels of ammonia (500-1500 
parts
per million), as well as tertiary treatment of solutions containing 
relatively
low levels of ammonia (10-50 parts per million).

    Dr. Gene Shelp, President and CEO of ENPAR, states that "historically,
the company files first in the United Kingdom in order to establish the
prior-art-date or date-of-disclosure, then patent applications are filed in
the United States, Europe, and Canada, and then in other jurisdictions of
interest".

    The handling of sludge produced from municipal waste water treatment
represents a major challenge for all levels of government as they strive to
develop a risk-free management strategy. A key approach is to develop a
biosolid product from the sludge, which is free of environmental concerns 
and
can be applied directly to the land. Alternatively, energy can be extracted
from the biosolids via various burning technologies. Regardless of the
ultimate fate of the biosolids product, water must be removed from the 
sludge,
and this water contains ammonia at toxic levels. The AmmEL-HC System is
proving to be extremely effective in converting this ammonia directly into
environmentally friendly nitrogen gas. The AmmEL-HC System enables
municipalities to achieve year-round compliance with government-mandated
environmental standards and regulations.

    ENPAR is a "Technology Company" applying its patented and proprietary
"Electrochemical Technologies" to the treatment of waste water and drinking
water contaminated by metals or nutrients i.e., nitrate/ammonia associated
with the mining, metal processing, chemical, agricultural, municipal and 
waste
management sectors. The common shares trade on Tier ll of the TSX Venture
Exchange under the symbol "ENP".
