The Deltec Fluidized bed filters are better known as the Rowaphos reactor because the fluidised bed filter is frequently used with Rowaphos (phosphate remover). However, it can also be used for filtering over coal, biopellets for biological filtering using bacteria or as a fluid bed sand filter.
These high-quality fluidized bed filters are equipped with a twist off bayonet cover. This facilitates access to replace the media. The water is supplied via the central tube and is led back upwards by a diffuser plate.
