  • Patent number: 11547971
    Abstract: A ceramic filter membrane module enables a fluid to be filtered, such as raw water, with higher efficiency using multiple ceramic filters in a housing. As the diameter of a through-hole located at the center is considerably larger than the diameter of the surrounding flow path, water pressure pushing the raw water is applied from the through-hole at the center toward the outside of a filter body, such that the raw water passes through the filter body smoothly, thereby improving the purification efficiency and uniformly setting the overall flow direction of the raw water. As packing members are installed and fixed between the housing and the ceramic filters, sealing of the incoming raw water and the filtered water becomes more effective, such that the risk of leakage is reduced. As a plurality of ceramic filters are housed in a single housing, economic benefit can be achieved.
