WATER TREATMENT SYSTEM

A water treatment system is provided, which includes a gauging well configured to temporarily store a source water therein, an integrated inclined plate sediment portion configured to mix the source water supplied from a feeding pipe of the gauging well with a drug, and coagulating and settling the source water, a filtration portion configured to filter out treated water which is completed preliminary treatment at the integrated inclined plate sediment portion, a sterilization portion configured to sterilize a filtrate water from the filtration portion, a turbidimeter provided on the feeding pipe to measure turbidity of the source water, a drug pump configured to supply the drug of a drug tank to the inclined plate sediment portion, and a controller configured to control the drug pump to adjust an amount of the drug to be supplied to the inclined plate sediment portion in accordance with turbidity as measured at the turbidimeter, in which the integrated inclined plate sediment portion includes a mixing basin where the source water and the drug are allowed to react with each other, a sediment basin connected to a rear end of the mixing basin to discharge a sludge formed as a result of reaction with the drug to outside, and an inclined plate unit formed inside the sediment basin to separate the sludge from the source water.
