Tag: Energy recovery

Sometimes, a picture is worth more than a thousand words. In the image below, you can see an industrial water supply system with two pressure reducing valves installed in series.

Our engineers have recently visited the site and assessed that the dissipated pressure can instead be transformed into electricity with one of our turbines. This will reduce the energy demand and the customer’s carbon emissions, while ensuring the same pressure reduction effect currently achieved by the valves alone.

If you have a site with potential for energy recovery, do not hesitate to contact us. We will develop a suitable pre-feasibility assessment for you to evaluate the hydropower potential.

The Easy Hydro team visited a hydropower plant to assess the potential for hydropower generation using the environmental flow with a cost-effective turbine to be installed in parallel to the existing groups. The existing potential is currently being dissipated by a reservoir discharge control valve.

The Easy Hydro team together with some other partners of the iAMP-Hydro project visited various PPC hydropower plants where the digital solutions developed in the project will be validated. The visit was very fruitful in order to confirm the details of the existing SCADA and the plant’s operating strategy.

In the coming weeks, the lab work will commence in order to develop and test the advanced conditions monitoring system and the predictive maintenance algorithms.

A special thanks to the PPC Renewables team for being such great hosts and for their hospitality! Stay tuned for further interesting updates in the coming weeks.

Easy Hydro on behalf of a large mining company has investigated the possibility of generating hydro power from the wastewater of a mineral processing plant which flows by gravity into a clarifier. The fluid is heavily loaded with fine quartz particles which have the potential to quickly erode mild metal components.

In order to guarantee a satisfactory life span for the equipment, Easy Hydro has specifically designed an energy recovery turbine capable of withstanding these harsh operating conditions due to a combination of a slow-moving impeller and an erosion-resistant polymer coating.

The Easy Hydro team visited an active landfill in southern Europe. Due to its location on a mountain top and in order not to contaminate the nearby aquifers, the site must continuously capture and treat the leachate. Produced by the organic waste decomposition process as well as the rainwater, which falls within the perimeter of the landfill.

To accomplish this, a treatment plant has recently been built to perform an onsite preliminary water treatment. The partially treated water then flows by gravity to a nearby urban wastewater treatment plant via a 6 km pipeline.

Easy Hydro is collaborating with the landfill operator to assess the feasibility of installing multiple turbines along the outfall pipeline which could help the site reduce the amount of electricity currently being imported from the grid.

Located in dry Southern Spain, this hydropower scheme was built in the 1960s and features a 650 kW Francis turbine. Even if the design capacity was adequate to the amount of water flow available at the time, the effects of climate change have caused a drastic reduction in water availability. As a result of this, the turbine has only been operated sporadically over the last decade since on most days there wasn’t a sufficient water flow to start the unit.

After diagnosing the situation and assessing the historical flow records, the Easy Hydro team recommended adding a low-cost Pump As Turbine (PAT) in parallel to the existing 650 kW unit. The new equipment was recently installed and will soon be commissioned, thus providing a stable 90-100 kW power generation and utilizing the water that otherwise bypasses the main turbine.

A water utility in Northern Spain is set to reduce its electricity bill thanks to an Easy Hydro energy recovery solution.  A 50 kW turbine now sits at the inlet of a treatment plant, supplied by a gravity-fed water source.

For this project, Easy Hydro provided the design expertise and the equipment (turbine, valves, electrical and control panels) required to complete the project.
