PURPOSE: A submerged type membrane filtering apparatus with a contamination preventive function is provided to cleanly maintain the quality of membrane filtering water by monitoring the contaminated state of a membrane filtering module using a sensor. CONSTITUTION: An air cleaning unit(30) cleans a plurality of membrane filtering modules with air. A membrane filtering unit assembly(20) is easily installed and separated by each membrane filtering module. Membrane filtering water is transferred to each membrane filtering module through transferring pipes(60). A contamination preventive unit(110) connects transferring pipes and transfers a signal detected by a contamination monitoring sensor to a controller in order to supply cleaning chemical.
