Australia’s Largest Ultraviolet Disinfection System

Trojan Technologies (Germany) and exclusive distributor in Australia, Aquatec-Maxcon PTY Ltd., have been selected by the Eastern Tertiary Alliance to provide the ultraviolet (UV) disinfection system for the Eastern Treatment Plant Tertiary Upgrade Project in Melbourne, Australia. Trojan will be supplying seven closed vessel (in-pipe) UV reactors equipped with revolutionary TrojanUV Solo Lamp™ Technology. The UV system will disinfect average and peak tertiary treated effluent flows of 380 and 700 million liters (101 and 187 million gallons) per day respectively, making it the largest UV installation in Australia.

The objective of the upgrade project is to significantly improve the quality of treated water at the plant. This will further reduce the impact associated with the current discharge quality on the receiving marine environment Boags Rocks, near Gunnamatta Beach, as well as produce a high quality recycled water resource which can be used for a broader range of non-potable recycling applications. These include residential third-pipe schemes (e.g. toilet flushing, garden watering, car washing), watering public gardens and irrigating food crops.

“This is the kind of environmental solution we’re proud to be part of; one that will have immediate positive impact on aquatic life and recreational waters,” says Marv DeVries, president, Trojan Technologies. “We’re proud to have our new Solo Lamp™ selected and stand out as the disinfection technology of choice.”
