Waste Water Energy Recovery – The Final Frontier

Wael will be presenting about the opportunity to recover energy from waste water. In mechanical designs, domestic water is usually a huge energy user. Generally, we only use domestic water momentarily and then it goes down the drain. The presentation will look at different opportunities to recover that energy from the drain water and give examples of how we can use that recovered energy in mechanical systems.
