Specialists in water and wastewater technology
Technical Consultancy, Advice and Company Training by Judd Water and Wastewater Consultants
Judd Water and Wastewater Consultants is owned by Simon and Claire Judd. We offer technical consultancy, advice and company training worldwide. We are based just outside London in the UK.
Our services are based on Simon Judd’s 40 years’ experience in water and wastewater treatment, as an academic and from his extensive work with industry clients. Although widely recognised as a specialist in membrane bioreactors (MBRs) and membrane technology, his work has encompassed most water and wastewater treatment technologies.
A little bit about us

Our latest book ‘What are MBRs? A pocketbook of membrane bioreactor technology’ (2026) includes digital material for more extensive knowledge.
We created and manage The MBR Group – a discussion forum on LinkedIn.com which currently has 14,000+ members.
According to the academic database ‘Scholar GPS’, Simon is the #1 most highly-ranked scholar in membrane bioreactor research (at December 2025).
