Abstract: A concentration adjustment unit adjusts a concentration of a fiber solution. An element forming unit includes an element forming tank, which receives the concentration-adjusted fiber solution, and a suction jig, which draws the concentration-adjusted fiber solution and accumulates fibers, which are contained in the drawn fiber solution, on a surface of the suction jig to form a filter element. A recovery unit includes a reservoir tank, which reserves recovered water that is drawn and is recovered through the suction jig. A filtration unit is provided in the recovery unit. The filtration unit includes a filter, which filters the recovered water, and jet nozzles, which remove the fibers, which are accumulated on a surface of the filter upon drawing and filtering the recovered water through the filter.
