NORTH SHORE WASTEWATER TREATMENT PLANT DELIVERS OUTSIZED BENEFITS ON DIMINUTIVE SITE

A RTIST RENDERING : A CCIONA /M ETRO V ANCOUVER

The treatment process will remove organic matter, collecting the sludge from primary and secondary processes into anaerobic digesters that convert it to biogas and a reduced amount of biomass. A co-generation engine will then condition and combust the biogas to produce electricity and heat for use within the facility. Energy will also be recovered from eÕuent to heat oÆce space in the plant. Lillian Zaremba, P.Eng. and Senior Project Engineer, Utility Research and Innovation with Metro Vancouver,

emissions, expecting to reduce greenhouse gases by 75 percent over the existing plant. And this achievement is made even more remarkable considering the footprint constraints of its tiny urban site. ENERGY RECOVERY AND EFFICIENCY Recovered energy from captured biogas from the wastewater treatment process will provide heat and power for in-plant use.
