Wabag Wassertechnik AG has been awarded two new contracts for its BIOPUR biofiltration process in Switzerland and Spain. The first project is in Windisch, Switzerland, which is in a nature conservation area, while the second is in a cliff cavern near a bathing beach in Llanes, Spain. Originally designed for 30 000 population equivalents, the Windisch wastewater plant is being enlarged to treat 90 000 PE. Wabag's two-stage BIOPUR biofiltration process with upstream denitrification is being used for the expansion, with a tertiary filtration stage in combination with powdered activated carbon or ozone addition. The €3.5 million Wabag contract includes the entire electromechanical equipment for the biofiltration process. Start-up is planned for 2015. Meanwhile Llanes' existing wastewater plant is being extended with a biological stage to treat 34 000 PE. Under a €0.5 million contract, WABAG is providing the basic engineering and selected components to a Spanish consortium headed by Sadyt, which will complete the project by 2014 as the general contractor.
