Abstract:
PURPOSE: A wastewater treatment equipment using magnetic filter is provided, which can remove impurities containing magnetic material by using a magnetic filter of low friction of flow, so that the filter can treat much wastewater with a small facility and can save filtering time, thereby resulting in less concentrated water of impurities. The filter can actively cope with various changes of various conditions of wastewater such as flow rate, temperature and pressure. CONSTITUTION: The system comprises the followings; (i) a wastewater tank (10) from which wastewater is fed to a magnetic filter tower (30) by a pump (11); (ii) a magnetic filter tower (30) in which two magnetic filters (33) with spray nozzles (32) are set upper and lower and wastewater is fed from bottom to top through the magnetic filters (33) for removing magnetic impurities, the washing of the magnetic filters (33) is carried out by cutting electric power to the electromagnet in the filter and spraying washing water through the spray nozzles (32); (iii) a concentrated liquid tank (13) for storing washed water of the magnetic filters (33) containing impurities; and (iv) a filtered liquid tank (12) for storing filtered water discharged from the top of the magnetic filter tower (30).
