In 2018, a regional water corporation in Victoria engaged FILTEC to design, supply, install and commission a new UV system to replace the existing disinfection system at one of its sewage treatment plants. FILTEC utilised its partnership with Trojan Technologies to optimise the operations and maintenance process for its customer.

The UV system had aged and was underperforming, and the treated effluent did not meet E. coli discharge requirements to be released to a local creek. There were spacing constraints for retrofitting the new UV unit as the existing shed was built around the old UV system.

Working closely with the water corporation, FILTEC designed a new system to optimise the operations and maintenance process.

The TrojanUV3000Plus was chosen because it is an open channel UV disinfection system. It has more flexibility for retrofitting, allowing the system to be installed outdoors with the removal of parts of the existing shed.

Furthermore, the Trojan solution allows easy replacement of lamps, and maintenance and repair work to take place without draining the whole system.

The new TrojanUV3000Plus not only treats water that meets the E. coli discharge requirements, but reduces operation and maintenance costs for the sewage treatment plant.

Prior to the upgrade, the UV system struggled to meet discharge requirements and the plant had to truck the effluent for disposal.

In addition, for maintenance and repair the utility had to drain the entire system, causing interruption and incurring costs. The upgrade has resulted in significant cost savings and operational improvements.

With over 25 years of experience in water and wastewater treatment, FILTEC is dedicated to delivering advanced engineered systems and cost-effective solutions for water and wastewater treatment projects throughout Australasia.

Trojan Technologies has the largest UV disinfection installation base in the world.
