Calgon Carbon Awarded Contract to Remove NDMA
PITTSBURGH, PA -- January 7, 1999 -- Calgon Carbon Corporation
announced today that it has been awarded a contract from Suburban
Water Systems of Covina, California, for a Rayox® Tower to destroy
N-nitrosodimethylamine (NDMA) in water from one of its wells that has
been shut down since NDMA was detected earlier this year. The
installation is also being supported by Southern California Edison
under its Showcase Opportunity and Economic Kilowatt Incentive
programs. The contract is valued at $565,000.
The Rayox® Tower, which will utilize Calgon Carbon's proprietary,
high-power, ultraviolet (UV) lamps, will treat approximately 3,000
gallons of water per minute and reduce the concentration of NDMA from
90 parts per trillion to less than 2 parts per trillion. The system is
scheduled for delivery in the second quarter of 1999.
A suspected carcinogen, NDMA is often associated with the use of
liquid rocket fuel and the manufacture of rubber or certain chemical
intermediates. NDMA has been found in a number of groundwater aquifers
in Canada and the U.S., and in recent years, improved analytical
testing methods have permitted the detection of NDMA in low
concentrations in drinking water.
Commenting on Calgon Carbon's expertise in destroying NDMA, John
Mickler, managing director of Calgon Carbon's Advanced Oxidation
Technologies group, said, "Our high-power UV lamps have proven to be
very effective in destroying waterborne NDMA. Over the past nine
years, Calgon Carbon has installed more than 10 Rayox® systems for
the destruction of NDMA in groundwater, drinking water, industrial
wastewater, and rocket washwater."
Calgon Carbon Corporation is a leader in the production, supply and
design of products, services, and technologies for the purification,
separation, and concentration of liquids and gases.
