Abstract
Provided are a cleaning apparatus and method for maintaining high efficiency intelligent separation membranes. The cleaning apparatus includes a raw water solenoid valve, a filtered-water solenoid valve, a backwash water solenoid valve, a drain solenoid valve, a first chemical tank, a second chemical tank, an online measurer, and a controller. The raw water solenoid valve is disposed at a raw water pipe to provide raw water to the separation membrane. The filtered-water solenoid valve is disposed at a filtered-water pipe to drain filtered water which is drained from the separation membrane. A one end of the backwash water solenoid valve is connected to the raw water pipe to provide backwash water of a backwash water vessel to the separation membrane through a backwash pump, and another end is disposed at a backwash water pipe which is connected to the backwash water vessel. The drain solenoid valve is disposed at a drain pipe which is connected to the raw water pipe to drain backwash water and chemicals which are drained from the separation membrane. The first chemical tank is disposed at the filtered-water pipe in parallel, and provides a first chemical to the separation membrane. The second chemical tank is disposed at the filtered-water pipe in parallel, and provides a second chemical to the separation membrane. The online measurer is disposed at the raw water pipe to measure a quality of raw water. The controller checks a total population of algae of raw water which is measured by the online measurer according to a predetermined time. The controller provides chemicals of the first chemical tank to the separation membrane when the total population of algae is less than a reference value. The controller provides chemicals of the second chemical tank to the separation membrane when the total population of algae is equal to or greater than the reference value. The controller chemical cleans the separation membrane for a certain time. The cleaning apparatus measures the quality of raw water to detect the total population of algae and change chemicals according to the total population of algae to clean the separation membrane, thereby enabling the efficient operation of the separation membrane. The cleaning apparatus extends the life of the separation membrane and thus can save cost expended in the replacement of the separation membrane. The cleaning apparatus prevents a load from being given to the pump due to decrease of the transmittance of the membrane and thus can save the driving cost of the pump that is expended in running.
