GE’s Water & Process Technologies is collaborating with the University of Guelph (U of G) in Ontario, Canada, on a federal government-funded, research initiative to maximise renewable energy generation and simultaneously produce a pathogen-free biosolids fertiliser. A grand opening of the new pilot was conducted. It is located at the Southern Ontario Water Consortium (SOWC) wastewater demonstration facility adjacent to the city of Guelph wastewater treatment plant.

Water & Process Technologies’ aspirational goal is to shift wastewater treatment from a burden to an opportunity where valuable resources can be extracted—namely renewable energy, clean water and fertiliser, according to the company. Enhancing anaerobic digestion through biological hydrolysis technology is reportedly one of the keys to realising this goal. Biological hydrolysis technology maximises the efficiency of existing anaerobic digestion infrastructure by increasing its throughput capacity by up to three times, according to GE. This enables plant owners to treat more sludge and other organic materials, increasing biogas production that can be converted to renewable energy. At the same time, a valuable pathogen-free fertiliser product is produced.
