<p>The invention provides a water processing method and a water processing apparatus. The water processing apparatus enables original costs and maintenance costs to be restricted, and is capable of detecting a blocking state of a film. The water processing apparatus comprises: a film module (2); a liquid feeding pump (P1) allowing processed water to pass through the film module (2); a power meter (22) for measuring power cunsumption of the liquid feeding pump (P1); a flow meter (23) for metering the flow amount of the filtered water that pass through the film module (2); and a cleaning time detection unit (30) for calculating power consumption per unit of flow of the liquid feeding pump (P1) based on measuring values from the power meter (22) and the flow meter (23), wherein if a value corresponding to the power consumption exceeds a prescribed value, the cleaning time is determined to be up.</p> |
