A liquid filtering device includes a filtration membrane unit, cleaning means that cleans a filtering surface of the filtration membrane unit from a side to which a water to be filtered is supplied, and pressure-detecting means that detects a differential pressure between before and after filtration by the filtration membrane unit, in which the filtration membrane unit includes two filtration membranes. A ballast water treatment apparatus includes the liquid filtering device, in which the liquid filtering device is used as a filtering device of seawater, and the ballast water treatment apparatus is carried in a ship.
