However, the height of the sewage level of the quicksand filter is the key point of the operation effect of the whole device. If the sewage level is too high, the sand filter material cannot be automatically cleaned, which affects the filtering effect. If the sewage level is too low, the overflow of clean water is too large, and the filtered clean water flows directly out of the sewage outlet, which reduces the water output and increases the sewage volume, affecting the entire treatment system. For this reason, we propose a quicksand filter with adjustable sewage level height. Utility Model Content
