The inclined plate packing is mainly made of a blend of ethylene propylene copolymer and polypropylene materials. Based on the shallow bed theory, a sedimentation section with a reasonable sedimentation distance is set above the inclined plate, while the geometric shape of the lower part of the plate is controlled to form a stable contact clarification section. This is achieved through contact action and the shallow pool sedimentation mechanism, thereby separating flocs from water. Various spacing inclined plate packings are supported by plastic ribs of different heights, which are thermally fused to the inclined plates. Multiple ribs are required to support every two inclined plate sheets, making the assembly process complex. Moreover, the traditional inclined plate internal water flow channels are rectangular, suitable only for upward flow sedimentation tanks.
The slanted tube packing is primarily used for desilting at the inlet of water supply and drainage projects, sedimentation of industrial and domestic water, wastewater sedimentation, oil separation, and tailings concentration treatment. It can also be applied in the renovation of old ponds. Currently, there are two types of slanted tube packing available: slanted tubes and straight tubes. The materials available are polypropylene and ethylene propylene copolymer.
