Contact Dr Ewan McAdam

Areas of expertise


Dr McAdam worked in industry for five years before joining Cranfield, initially as an analytical chemist for an executive agency of the UK's Department for Environment, Food and Rural Affairs (Defra) and subsequently as an analytical chemist for a global pharmaceutical manufacturer. Following on from these positions, he worked as a consultant across a range of industrial manufacturing sectors managing risk assessment and compliance issues with respect to gaseous and aqueous emissions, as well as leading on due diligence auditing. He returned to academic study in 2003 at Cranfield University to complete a doctorate in engineering (EngD) which focused on developing membrane bioreactors for nitrate removal from potable water and ion exchange brines. He has stayed within the Cranfield Water Science Institute to continue work on the development of novel membrane processes in addition to undertaking various projects focused on future energy generation, contaminant transformation, separations and resource recovery.

Current activities

He is a Reader in Process Engineering and is also programme manager for the STREAM IDC (  A particular area of expertise is in gas separation, where he is currently actively engaged with industry in developing new technology solutions for odour removal, biogas pre-conditioning to remove trace contaminants, enrichment of biogas to natural gas standards, and separation of dissolved gases from water (e.g. THMs, methane) to protect human health and enable energy recovery. In addition, Ewan contributes to the ‘sewage works of the future' theme at Cranfield Water Science Institute, having worked on the design of intensive and extensive anaerobic systems for temperate wastewater treatment, with an ultimate objective of providing enhanced local energy generation.
