TRILITY’s expertise and heritage is a critical part of the Company’s offering to its clients across the private and public sectors. Both enable the Company to innovate continuously across every operating site, drawing on the experience and knowledge delivered over two decades. It follows that every TRILITY employee has a commitment to developing effective solutions through engineering excellence for our clients using conventional and contemporary technologies.
Our approach means that we can support and enable the transfer of knowledge and expertise across to our client for the benefit of their business, customers and stakeholders. This enables TRILITY to build enduring and mutually beneficial relationships with a variety of stakeholders through collaboration or partnerships where there is a common objective.
Once an objective has been achieved at a particular site, TRILITY management ensures that these innovation activities are integrated across its business group and there is continued development for skills and process to support the introduction of new thinking or a new technology.
Innovation and technology at work
The Victor Harbor Wastewater Treatment Plant (WWTP) is a membrane bioreactor treatment process commissioned in 2005 and operated by TRILITY. The plant was designed to utilise polymer sludge thickening and clay-lined lagoons to dry the waste activated sludge.
TRILITY has overseen the upgrade of the sludge drying lagoons at WWTP. High rainfall caused these lagoons to become overloaded and form objectionable odours, leading to complaints from neighbouring residents, financial penalties and a letter issued from the Environmental Protection Authority requesting immediate and permanent actions.
TRILITY’s Operations and Engineering teams worked together to find a temporary solution to immediately mitigate the odour as well as a permanent, sustainable solution for the remaining operational years.
Water-capping was the most effective method for immediate odour mitigation and provided extra time to commence and complete the permanent solution of decommissioning the sludge thickener and installing underdrains. Not only did these upgrades significantly reduce sludge drying time and odour but they were more environmentally sustainable, more cost effective, reduced overall power consumption and enable the plant to provide greater volumes of reuse water to the community.
