Description

Washing type filter, water quality management system including this filter, and water quality management method The present invention relates to a washing-type filter that cleans various foreign substances attached to the outer surface of a filter by having a washing means automatically move in both directions to reliably detach the foreign substances, a water quality management system including the filter, and a water quality management method. Generally, water treatment methods for filtering foreign substances contained in raw water are classified according to the treatment principle into biological treatment, which removes organic matter by microorganisms; chemical treatment, which removes heavy metals using chemicals; and physical treatment, which removes impurities and solids by machines such as screens. Here, the filtration process, which is one of the physical treatments, involves introducing raw water containing contaminants into a filtration device to filter out the contaminants using a separate filter, thereby discharging clean treated water. If the filtration process is carried out for a long time, the amount of foreign matter attached to the outer surface of the filter gradually increases, and the filtration performance deteriorates; in this case, all foreign matter attached to the filter is removed through a backwashing process and then discharged to the outside. However, since foreign substances attached to the filtration filter are not reliably removed even by the backwashing process, a problem is occurring where filtration performance is not restored and filtration efficiency decreases. Therefore, there is a problem in that the backwashing process cycle becomes shorter, the lifespan of the filter decreases rapidly, and the replacement cycle of the filter becomes shorter, leading to increased maintenance costs.
