Low Energy Wastewater Treatment Systems

  • Duration: One day
  • Location: Cranfield campus
Low Energy Wastewater

Over 75% of all sewage treatment facilities in the UK treat the wastewater from less than 2,000 population equivalents. To ensure financial and operational carbon sustainability the water industry is looking for more innovative solutions to treatment rather than necessarily choosing to close these works to pump to larger facilities.

This specialist one-day short course covers the design principles of the most commonly used biofilm technologies, new developments in other low energy technologies, and offers practical tools for technology assessment, selection and research.

Course Objectives

On successful completion of this short course you will be able to:

  • Describe key components and design criteria employed for all the technologies covered
  • Critically assess and select technologies, commercially available or new developments, according to the key pillars for technology selection based on project or treatment scheme drivers.

These outcomes are expected to aid participants when working in process engineering, research and development, and investment planning roles in the water industry.

Course Topics

The introductory lecture covers the principles required for understanding biological treatment systems and sets the scene for technology appraisals, innovation and design. The removal mechanisms for each the technologies will be covered in detail to enable a fundamental process understanding. Each technology will be discussed in terms of process resilience and reliability, tradeoffs, and future proofing.

  • Definition of 'low' energy treatment systems and principles of technology assessment
  • Design, performance, innovation, tradeoffs, and challenges of LETS
  • Case studies from the UK and the rest of the world
  • Trickling filters
  • Rotating Biological Contactors
  • Wetlands and Reed Beds
  • Algae bioreactors
  • Next generation anaerobic ponds
  • Putting it all together – creating robust flowsheets.

Who should attend

Those in roles in process engineering, research and development, and investment planning roles in the water industry.
