In collaboration with the Spanish company ESEKI, a Banki IREM TBA 2-0.8 turbine-generator unit with a capacity of 15 kW was installed at the Urdalur wastewater treatment plant in Spain.
In water distribution systems, excess pressure is often dissipated through pressure regulating valves, resulting in the loss of potentially valuable energy. In this project, a PRV bypass was implemented, diverting the flow towards the microturbine to generate electricity without affecting pressure regulation or the plant’s water supply.
Thanks to its design, the turbine automatically adapts to the available flow rates, ensuring efficient plant operation.
What are the key features of this installation?
- Compact and robust design: allows installation in limited spaces and ensures long service life with minimal maintenance requirements.
- 15 kW renewable energy generation: reduces operational costs and dependence on the power grid, supplying part of the energy required by the water treatment plant.
- Use of residual energy: optimizes system performance by recovering energy that would otherwise be lost.
- Carbon footprint reduction: lowers emissions associated with conventional electricity consumption.
- Replicable model: suitable for other water treatment plants, distribution networks, and industrial systems with overpressure.
This project is a clear example of how BANKI and PELTON IREM micro-hydroelectric solutions can be integrated into existing infrastructures to enhance energy efficiency and contribute to a more sustainable future.
