From incineration to digestion over 10 years: PRESENTATION ONLY

Jolly, M.1 and Taylor, T. 2, 1 Black & Veatch, 2 Yorkshire Water, UK


Plenary talk 

Yorkshire Water have a plan to close down four sewage sludge incinerators that have been the main disposal route for sludge produced in the Yorkshire area since the 1990s. The incinerators are being replaced by thermal hydrolysis and mesophilic anaerobic digestion (MAD). Black & Veatch are currently working on a scheme to build a new sludge treatment facility at Knostrop in Leeds to treat up to a maximum of 48,000tds/year of sewage sludge. This involves MAD followed by lime addition and liquor treatment by the DEMON process.
