One of the filters is a membrane filter which produces waste water discharged through a discharge conduit. The discharge conduit is connected to an inlet of a discharge valve mounted on the main body. The discharge valve also includes an outlet for discharging the waste water received from the inlet. The discharge valve includes a passage and an additional conduit communicating the inlet with the outlet. The passage is opened and closed by a manually operated valve body, and the additional conduit is opened and closed by a solenoid valve.
