심재호Jai Ho Shim
Abstract
Recently, as the raw water quality becomes to be polluted, and the seasonal and local variation of water quality becomes to be severs, a quantity or automatic control of coagylant dose have been required in the water treatment plant. The importance of quantity control of coagulant has been raised to enhance the water quality and water treatment efficiency, however, a low mechanical confidence and system organizing technique of the coagulant feeding system makes it difficult at this circumstance. Therefore the combination of the magnetic flow meter and control valve was set to improve the present coagulant feeding system and SCD(Stream Current Detector) which could sense the coagulating condition will be also tested to control the coagulant feeding rate automatically with water quality by the feed-back control mechanism. Hope improvement of water treatment technique by review of quantity control and feed back coagulant feeding system in consideration of changes in the raw water quality.
