<p>PROBLEM TO BE SOLVED: To provide filtration equipment having a deliquoring function.SOLUTION: Filtration equipment 11 includes a pump 12 for pumping up liquid L stored in a tank T, a cyclone type separator 13, a sludge pot 14, an on-off valve 15, a gas-liquid permeable filter 16, a switching valve 17 and an ejector 18 which are configured as an integrated unit. The cyclone type separator 13 centrifugally separates sludge S from liquid L discharged from the pump 12 while swiveling the liquid L and causes the sludge S to precipitate. The gas-liquid permeable filter 16 serves as a sludge container for storing the sludge S separated from the liquid L. The switching valve 17 selects one of two pieces of piping 32,33 of a return passages for returning the sludge-removed liquid L flowing out from a central upper part of the cyclone type separator 13 into the tank T. The ejector 18 provided in one piping 33 has a gas suction port 34 and the gas suction port 34 communicates with a downstream side of the filter 16 via the piping 35.</p> |
