Phosphorus is both an essential nutrient for life and a pollutant in freshwater environments.  Point discharges from wastewater treatment plants are an opportunity to control and even recover phosphorus.  In the UK, legislation has driven widescale implementation of chemical dosing in response to meet tightened phosphorus consent limits.  These largely incorporate chemical dosing and technology to remove the solids generated.  To meet and maintain compliance levels, operators, process scientists and managers will need to understand the principals of chemical dosing, the impact upon the treated wastewater (e.g. in terms of alkalinity consumption, chemical breakthrough) and the actions that can be taken to optimise. 

In addition, larger sites will in the future see P consents and this will drive investment in Biological Phosphorus Removal and nutrient recovery.

This course works through each aspect of chemical and biological treatment, reviews proprietary technologies and provides attendees with the basis to develop control and optimisation strategies for their sites.

Course Aim

To understand the factors influencing chemical and biological phosphorus removal.  This includes worked examples on calculating chemical dose rates, solids removal and proprietary technologies and configuring activated sludge plants for biological phosphorus removal.  Nutrient recovery technologies will also be discussed.

Learning is delivered through a combination of lectures, case studies and worked examples.

Course Programme

  • The importance of characterising and fractionating wastewater for P removal
  • Chemical phosphorus removal including worked examples for determining optimum does rates and sludge generated
  • Technologies for removing phosphorus and the suspended solids generated
  • Biological phosphorus removal
  • Innovations for phosphorus removal
  • Nutrient recovery, principles and technologies

Trainer Profile

Matthew Smyth  BSc, MRes, MBA, MCIWEM CSci CWEM

Technical Director

Matt has been in wastewater and sludge for twenty years and works with water companies, industry and waste producers to develop and implement solutions.  He’s been delivering courses on tertiary and advanced wastewater treatment for several years and has now focused this course to reflect the increasing importance of phosphorus.  He championed Aqua Enviro’s 2017 event, ‘The Big P’, which saw the findings of the Chemical Investigation Programme presented and has worked on numerous projects to evaluate the environmental benefit and costs of phosphorus removal and recovery.
