4th July 2017 - 5th July 2017, Manchester United Football Stadium
This two-day conference and exhibition will explore the balance between reducing phosphorus consumption within catchments, and effective means for recovering phosphorus as a nutrient. The findings from the UKWIR low-P trials to evaluate source control technologies will also be presented.
“The UKWIR National P Trials steering group is very happy to be supporting the BIG P conference and will be using the event as a platform to disseminate the findings from the low-P trials”. Pete Vale, Technical Lead – Innovation, Severn Trent Water.
This event will bring together experts in the field of phosphorus, technology suppliers and operators. It is the must attend event for anyone considering Phosphorus removal and/or recovery.

Phosphorus is currently the limiting factor preventing good chemical status under the Water Framework Directive for UK inland surface waters. Phosphorus is also a finite resource, used extensively in modern domestic practice from detergents to fertilisers, it is even used within drinking water networks to prevent lead dissolution.
Typically, aerobic wastewater treatment does not substantially reduce phosphorus concentrations and WwTW’s therefore become a point source discharge. Diffuse sources are often also present, although often less controlled for example through fertiliser runoff.
Removal of phosphorus from point source discharges into the water catchment will create real ecological benefits within waterways, this has driven new discharge consents and as a result technologies and methods have been developed to reduce effluent phosphorus concentrations to sub 0.5mg/l levels.
Since Phosphorus is finite, technologies and methods have been developed to recover it, particularly as struvite fertiliser. The current market value of phosphorus is low and as a result, economic recovery is a challenge, However, there are other enabling drivers that allow the capital and operating cost deficits to be internalised, including the nuisance associated with struvite precipitation, the impact of P on dewatering processes and broader benefits derived from reduce greenhouse gas emissions associated with reduced usage of phosphorus fertilisers.
Before capital and operational solutions are brought to bear, a thorough, detailed understanding of methods of removal, control and recovery is needed. Furthermore, understanding the types of phosphorus and phosphorus compounds within wastewater streams and the most appropriate methods to treat each type of compound will be invaluable in ensuring effective technology selection for Phosphorus removal from point sources.
