Water companies are moving away from viewing their wastewater as a problem seeing it more as a potentially valuable commodity. We need to realise the potential of wastewater treatment facilities as factories for resource recovery.
Technology is now available to focus wastewater and sludge treatment on resource recovery. But choosing the optimal mix of technologies to recover energy, nutrients and exotics, that maximises added value and makes best use of existing processes, is complex; getting it wrong can jeopardise compliance or increase costs.
This project will:
- extend the well-established PlanIT-STOAT strategic wastewater modelling software to evaluate costs, benefits and impact of resource recovery processes in an existing treatment train.
- establish a Resource Recovery User Group (RRUG) to screen and short-list up and coming, promising technologies.
BUSINESS BENEFITS TO CLIENTS
- Allow investment targeted on new process plant to be retrofitted with minimum risk to compliance, to increase revenue from the production of renewables and fully capitalise on government incentives.
- Provide confidence in procurement of new technologies that have been independently assessed and verified.
- Provide participants with a strategic tool to aid selection of new processes to complement existing treatment configurations and understand new technology benefits and limitations.
- Assess technologies and systems that provide recovery of resources and identify what impacts each has on the performance of the overall treatment train.
- Extend the PlanIT-STOAT framework to resource recovery processes.
- Organise a RRUG workshop for technology providers to showcase new solutions, benchmark claims and identify where the technologies would be best deployed.
PROJECT OUTPUT AND IMPLEMENTATION
- Enhanced PlanIT-STOAT-Resource-Recovery tool that will enable optimum placement of new processes within the wastewater and treatment train to maximise business benefit and minimise risk of compliance being compromised.
- A technology selection platform to: benchmark technologies; define their scope of application and potential for delivery of resource value; and facilitate integrated treatment process for resource recovery.
