The Energy Institute Yorkshire branch would like to invite you to the following technical visit.


During the 1990s, Yorkshire Water constructed incinerators at four locations to burn wastewater sludge. This sludge strategy was founded on the need to deal with sludges with high concentrations of metals. With the incinerators coming to the end of their life, Yorkshire Water has re-considered its strategy in the light of lower metal concentrations in the sludge allowing the potential to recycle sludge to land. Incinerators at facilities within North Leeds and Sheffield have been closed down and replaced respectively with thermal hydrolysis and mesophilic anaerobic digestion (MAD).

The economics of MAD has led Yorkshire Water to continue the replacement of their remaining incineration installations at Knostrop (South Leeds) and Huddersfield with the same technology.

The overall strategy has led to the construction of a new 30,000tds/a mesophilic anaerobic digestion project at Knostrop, which includes the generation of electricity from the generated Biogas in CHP engines and DEMON technology being used for sludge liquor treatment.

The visit will consist of a presentation followed by a tour of the facility, which is in the final stages of being commissioned and performance trials being undertaken.

PPE Requirements: The following PPE is mandatory for the tour: laced safety boots, hi-viz, helmet, eye protection, safety glasses, and gloves.

Directions: Approach the site off the A63 (Pontefract Lane), turn onto Knowsthorpe Gate, and then left into Knowsthorpe Road, and after approx. 150m turn left into the site entrance (before getting to the Hanson Cement Depot). Drive up to the site gate, to be signed in and given directions to the site office.
