Fee: £295 plus VAT for 1-person, (includes slides presented).  20% discount on total price if all three courses booked at the same time: Activated Sludge & Wastewater courses

Course Overview

Over 80% of sewage sludge produced in the UK is treated by anaerobic digestion and advanced anaerobic digestion.  The biogas produced is a renewable energy source and can be used to generate electricity and heat or converted into biomethane for grid injection, whilst the biosolids produced are generally dewatered and applied to land.

Operators and managers are faced with the challenges of increasing energy production whilst minimising the costs associated with digestate disposal/recycling.  There are many factors that influence the financial balance.  With the advent of 2020 and a competitive bioresources market delivering upon innovation and efficiency, now more than ever it is vital to understand revenue and cost drivers at the site and business levels.

This course is aimed at operators, optimisers, process scientists and managers in the wastewater/sewage sludge sector.

Course Aim

Each one tonne of dry solids produced from wastewater contains 4-7 MWh of energy, the quantity recovered is a function of the digestion process, asset condition and quality of feedstock.  The digestate produced is both a cost to handle and an opportunity to recover nutrients and produce a compliant product.

This course is designed to help attendees understand and act upon the factors that influence biogas production, sludge dewaterability, biosolids compliance, cost and revenue generation.

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

Course Programme

  • The different phases of AD & key terms
  • Advanced anaerobic digestion – thermal and biological hydrolysis
  • Metrics for digester operation including VFA: alkalinity, hydraulic retention time, organic loading rate and rate of volatile solids destruction
  • Commissioning digesters and takeover testing
  • Common operational problems & solutions including foaming and inhibition
  • Dewatering digestate, chemical dosing techniques and technologies
  • Liquor Treatment – understanding the nitrogen cycle, technologies in the marketplace and optimisation
  • The Biosolids Assurance Scheme

Optional extras

  • a 1-2-1 follow up with trainer Matthew Smyth to reinforce learning at £205 plus VAT (2 hours).
  • a 1-day course, tailored to your requirements, is a popular choice by water companies or contractors to have delivered on their sites to operational staff. Please contact matthew.smyth@aquaenviro.co.uk if you’d like to discuss this option.
