Extracting value from sewage sludge


Barber, WPF

Proceedings of the IWA Sludge Tech conference, 2016

Abstract

Although wastewater and sludge are resource‐rich, wastewater treatment works were designed to destroy rather than recover value. Water within wastewater is routinely returned to waterways and not used, whilst nutrients such as nitrogen and phosphorous are destroyed using chemical and biological nutrient removal techniques.

Only between 15 to 20 % of the nutrients are recovered, assuming the biosolids are used in agriculture as a fertilizer product. Learn more about extracting value from sewage sludge by Cambi Technical Director, Dr Bill Barber.
