Running Gear: One Francis turbine with 10 kW induction generator.
Scope: Controls, switchgear, utility interconnection, wicket operator, and belt drive generator.
This project is an energy recovery system for a municipal water pollution control facility in Ohio. Treated municipal wastewater, which flowed from a de-chlorination tank over a weir, now operates the turbine that uses all flow up to 15 MGD. The generator operates in parallel with grid power and reduces the electrical usage of the facility.
The generator, mechanical and electrical systems were designed in close cooperation between PHT and The James Leffel and Co., resulting in an integrated, water-to-wire solution. The digital controls provide fully automatic operation and a color touch panel user interface for the plant operator.
