Concrete filter plate 

The filter plate is a key device in the water treatment process, which plays a dual role in the filter tank to carry the filtering of the filter material layer and back flushing water (gas) distribution. The quality of the filter plate (especially the flatness and precision of the filter plate) is directly related to the filtered water quality, water volume and long-term operation benefits of water plants and sewage plants. The traditional water distribution system of the filter tank has large resistance in filtering and backwashing, uneven water distribution, many dead water areas, and the filter material is easy to harden and accumulate mud. At the same time, due to the local flushing intensity, the supporting layer is loose, and sand leakage and other adverse consequences occur.
