The present invention relates to a method and an apparatus for treating washing water using a coagulation-ceramic ultrafiltration membrane. The water treated by the method and the apparatus can be reused as washing water. According to the present invention, the method for treating washing water is characterized by sequentially carrying out the following processes: a coagulation-combined ceramic ultrafiltration membrane process including a coagulation process and a ceramic filtration membrane process; an ion exchange process; and a reverse osmosis (RO) pressure type filtration process. The production of high quality and ultrapure production water is possible by the method for treating waste water, and the method can reduce membrane fouling in the rear stage processes ( an ion exchange system, RO process), which further leads to reduction in operation costs. |
