What steps is your facility taking to practice energy recovery?

10/29/14 webinar covered:

WERF’s ENER1C12 research on energy neutrality or “net zero” for water resource recovery facilities is aimed at characterizing the energy balances of common wastewater treatment configurations and evaluating the potential for employing best practices and innovative but demonstrated technologies to improve wastewater treatment energy balances. The research profiles success stories of energy neutral or near-neutral facilities and provides guidance to water resource recovery facilities on how they can follow the “roadmap” that will enable them to locate or benchmark themselves and chart their own path to net zero.

The Philadelphia Water Department will share its experiences and insights on striving for “net zero”.

Also during the World Environmental health Day seminar series: Patrick Lucey talked about the Triple Bottom Line approach of Dockside Green in British Columbia.

Sustainable Fish Farming?

Is this sustainable practice? There are many cases of so called sustainable practices across the globe. But question here is how fit the fish raised in sewage for human consumption? Even if with full or partial treatment, there is a lot left in the wastewater to get accumulate in the fish due to their higher tolerance towards toxic substances. We can count many pollutants of interest e.g. detergents, PPPs, Trace Elements, Micro Pollutants, list could be exhausting. If fish for human consumption is raised in such waters, is there any study conducted to assess the edibility of the fish? Is there any database available which describes how much pollutants of concern are getting accumulated in fish and to what level they could affect human beings?
