Project Appreciation and Objectives
A large number of innovative wastewater treatment technologies, many of which claim significant performance improvements, are appearing on the market. Often the processes are in the early or embryonic stages of development and the claimed advances are an innovative use of an established technology, rather than a complete new technology. WASC's are aware of the need to identify energy efficient processes to enable them to balance the challenges of their wastewater quality improvement programme with the need to reduce energy use and carbon emissions.
This project will identify emerging technologies and examine case studies, pilot trials and reference sites to determine their potential for achieving improvements in treatment performance and efficiencies. The project will:
- Undertake a review and assess the technical capability, cost-effectiveness and carbon footprint of emerging technologies in wastewater treatment. Identify suitability for installation including limitations of retrofit/installations in order that WASC's can understand the practicalities of using novel processes.
- Produce a database of novel and new wastewater treatment technologies that will enable improved investment decisions to be made.
Benefits to Clients
- Improve the capability and robustness of existing wastewater treatment processes for compliance with more stringent consents without the need for additional investment in asset replacement.
- Reduce the current level of uncertainty/risk of failure with new processes and minimise the investment risk from a technical and financial perspective.
- Make better investment decisions relating to emerging wastewater treatment technology.
- Undertake a detailed review of recent advances in emerging wastewater treatment technologies.
- Conduct a full performance/capability assessment of short-listed treatment options.
- Assess the capital and operating costs of short-listed treatment options.
- Review retrofit/installation practicalities.
- Produce recommendations on the suitability of the short-listed processes or options.
The output of the project will be a collation of a database of emerging wastewater treatment technologies, their whole life costs (capex / opex), carbon emissions and process robustness / reliability. An assessment of their performance, cost-effectiveness, reliability and robustness will be made to substantiate the performance claims and their applicability for the UK Water Industry.
