Abstract

An ultrapure water supplying apparatus may include an activated carbon filtering device, an ion exchange resin device connected to the activated carbon filtering device, a reverse osmotic membrane device connected to the ion exchange resin device, a hollow fiber membrane device connected to the reverse osmotic membrane device, a first fluid driving part between the reverse osmotic membrane device and the hollow fiber membrane device, and a control unit configured to control the first fluid driving part. The first fluid driving part may include first, second, and third pumps, which are connected in parallel to the reverse osmotic membrane device, and a pressure sensor located between the first pump and the hollow fiber membrane device. The control unit may be configured to control each of the first, second, and third pumps, based on a signal transmitted from the pressure sensor.
