THURSDAY 18 MARCH 2021 / 10:00 - 13:00 (GMT+1)
Keith Knox, Knox Associates (UK) Ltd
Recirculation of leachate has been practised for more than 40 years and is now commonplace around the world. Often it has been undertaken with little prior design thought and insufficient monitoring. During the last decade, the subject has been reviewed in a more structured way, with regard to objectives, design, operational performance data and monitoring of effectiveness and impact.
The aim is to make the Webinar as interactive as possible, with delegates introducing themselves and describing any recirculation projects or issues that they are involved in. During the presentation of webinar materials, delegates are encouraged to raise issues, discuss case studies and aspects of particular interest to them.
Webinar materials will be presented and discussed according to the following structure:

He has a strong interest in tropical landfills, landfill sustainability and reducing the aftercare period. He has been at the forefront of technical developments in leachate treatment, including ammonia nitrification, single tank SBR pre-denitrification, use of activated carbon, and high temperature stripping of ammonia. His research has included technical reviews of e.g. water balance, co-disposal, leachate recirculation, and leachate hard COD, as well as many experimental investigations. Keith has been involved in many leachate recirculation projects and in recent years has co-authored several technical review reports for organizations in the UK and Denmark.
