Option 1.  Davyhulme Advanced Sludge Treatment Plant:              

United Utilities flagship Advanced Sludge Treatment Plant at Davyhulme, Manchester

You will have an opportunity to see the whole of the sludge treatment train from the import cake silos, pre-dewatering centrifuges, Cambi Thermal hydrolysis plant, digesters and dewatering, as well as the NEW Malmberg BIOMETHANE PLANT.  The site aims to process 91,000 tonnes of dry solids per annum and the tour will be led by Tom Stead, United Utilities’ experienced Production Engineer, able to talk you through plant modifications and efficiencies made over the past 6 years.

The visit will also include a workshop and lunch designed to enable participants to network with one another and engage with experts in the field.

Davyhulme visit is sponsored by Helix ECL

Option 2. Saria’s ReFood Anaerobic Digestion Plant  SORRY, THIS IS NOW FULL

Commercial (waste-fed) facility, Widnes


You will have an opportunity to see the whole digestion process at a commercial (waste-fed) anaerobic digestion facility, from feedstock (e.g. preparation, pre-treatment), digestion and gas and digestate handling.

ReFood Widnes was Saria’s second Anaerobic Digestion facility in the UK and their first Gas to Grid plant. It is permitted to process up to 150,000 ton p/a following the recent expansion of the plant completed Spring 2017.

We are extremely privileged to tour ReFood’s anaerobic digestion facility at Widnes.  The recently expanded site processes up to 120,000 tonnes per year of solid and liquid food wastes.  The resulting biogas is upgraded and injected into the local gas grid, whilst the digestate is despatched from site as certified Biofertiliser for use by farmers.

Our visit will include a walk-through of the whole process, from receipt of wastes through de-packaging, digestion and biogas up-grading.  We will have an opportunity to view ReFood’s bespoke waste reception facilities, on-site laboratory and biogas upgrading facility – and to discuss approaches to odour management and process control.

Experts will be on site to answer questions on biogas upgrading, process management and optimisation in food waste AD, as well as digestate quality management and certification.

The visit will include a discussion on the challenges faced by AD facilities outside the Water Industry, what the future might hold, as well as allowing delegates to network with one another and experts in the field.
