Filtralite® Clean HR 3–6 has been installed in the first biofilter stage of the Pas de la Casa Wastewater Treatment Plant in Andorra, replacing the old filter media to significantly improve treatment performance and reduce both energy and water consumption.
Located in a sensitive mountain environment in the Pyrenees, the plant faces strict discharge limits and environmental requirements. In this biofilter stage, Filtralite® Clean is used for BOD removal, helping the facility meet demanding effluent standards and ensuring that treated water released into the environment is safe and compliant.
Thanks to its high porosity and large surface area, Filtralite® Clean enhances biofilm growth and ensures a stable and efficient biological treatment process. The improved biofiltration not only increases treatment capacity but also reduces operating costs by minimising backwash frequency and energy use.
The installation demonstrates how Filtralite® biofilter technology can save money and space, avoid odour generation, and improve overall performance compared to traditional biological treatment solutions. This makes Filtralite® Clean an ideal choice for wastewater treatment plants located in environmentally sensitive areas where sustainability, efficiency, and reliability are essential.
