Trickling Filters: Photo Gallery of Different Media Types

Examples of cross flow media, both of which were originally made by Munters Corp. Notice that adjacent sheets run in opposite directions, creating a flow pattern that crosses and creates mixing points. These two media have different surface areas (89 and 98 m2/m3) and are classified using the LTF models as XF-89a and XF-98b.
Example of vertical flow medium. This particular plastic module was made by BF Goodrich and contains two different faces: one has straight and curved vertical faces (as shown) but the other side is a flat sheet. This medium has a surface areas of 89 m2/m3 and is classified using the LTF model as VF-89b.
Example of another type of vertical flow medium. This plastic module was made by Surfpac. Notice the highly curved surfaces which act to increase the detention time in the medium verus that possible with just a flat face. This medium has a surface areas of 89 m2/m3 and is classified using the LTF model as VF-89c.
