There are now over 660 Anaerobic Digestion (AD) facilities in the UK processing a range of organic materials (such as sewage sludge, food waste, livestock manures and purpose grown crops/crop by-products) into biogas and digestate. During AD, much of the nitrogen in the feedstock is converted into ammonium, increasing the quantity in the resultant digestate. There are a number of approaches for the digestate, which include:
The right choice will be site specific and depend upon an array of factors including: the ability of the site to treat the ammonia load and meet its discharge consent to watercourse; landbank availability for digestate or dewatered product; markets for the recovered ammonium sulphate (or nitrate) or the cost-benefit of installing a new process.
Due to wider environmental factors, other countries are ahead of the UK in nutrient recovery, meaning established techniques already exist to recover the valuable ammonium, which is often currently lost into planetary cycles.
This event will investigate the options for managing ammonium, and seeks to bring together key stakeholders interested in advancing recovery, recycling and removal techniques.
Call for Papers
We are currently inviting abstracts on this subject. In particular papers are encouraged where operating data on specific technologies can be shared and used to promote discussion and to assist investment decisions.
If you would like to give a talk at the event, please submit the following details to firstname.lastname@example.org by Wednesday 18th January 2017.
