UV Technology to Be Used to Destroy NDMA for a Water Reuse Application
Trojan Technologies Inc. has received a purchase order to supply a 3 mgdultraviolet (UV) system to destroy N-Nitrosodimethylamine (NDMA), a harmful environmental contaminant.
Once treated, the reclaimed water will be injected into an aquifer to prevent salt water intrusion and protect groundwater supplies. The contract valued at approximately Cdn $2M was awarded to Trojan as part of the Alamitos Barrier Recycled Water Project located in Long Beach, CA USA. Along with the Trojan UV system, the Alamitos Water Treatment Plant will also utilize membrane filtration and reverse osmosis in the treatment process.
The Alamitos Barrier Recycle Water Project, sponsored by the Water Replenishment District of Southern California (WRD), will purify water for reuse, that would otherwise be discharged to the ocean.
"Using advanced water treatment technology, such as ultraviolet light for the destruction of NDMA, will purify water leaving the treatment plant to levels that exceed drinking water standards for NDMA," said Dr. Bruce Mowry, General Manager with the WRD. "This project, one of the first of its kind, will allow our local groundwater supplies to be protected from salt water intrusion which, if left unattended, would destroy invaluable drinking water supplies."
"This Alamitos Barrier Project reinforces Trojan's position as a leader in the Environmental Contaminant Treatment (ECT) market," said Marvin DeVries, Executive Vice-President Trojan Technologies. The ECT market is a new market opportunity for Trojan developed through the acquisition of AUVS in March, 2001. Revenues in 2001 were approximately $1.3 million and significant growth is anticipated in this market. The equipment will be shipped to the site in the summer of 2002.
Environmental contaminants are compounds that are mobile in water, toxic at low concentrations, resistant to biodegradation and difficult to treat by conventional technologies. Examples of environmental contaminants include NDMA, 1,4-Dioxane, and Methyl Tertiary Butyl Ether (MTBE), which are byproducts of many industrial manufacturing processes and often found in groundwater supplies.
