PROBLEM TO BE SOLVED: To freely perform the supply of new filter material and the taking out of waste filter material in a filtration equipment using a filter material having an adsorption function when the filter material is frequently exchanged for recovering the adsorption function. SOLUTION: A new filter material feed pipe, a new filter material storage tank, an air pipe, a new filter material air lift pipe, and a new filter material air lift outflow pipe are installed for the supply of the new filter material to supply it. In order to take out the waste filter material, the waste filter material is made to flow into a waste filter material storage tank by operating the air lift pipe of a filtration tank, an air pipe, and a waste filter material transfer pipe to store the waste filter material in the waste filter material storage tank, and a waste filter material transfer pump and an injector are installed to transfer the waste filter material to the outside of a system.
