When filtering highly turbid water, the mainstream method is to perform filtration after removing turbidity by coagulation, flocculation, and sedimentation process as pretreatment for filtration. On the other hand, since the “GL” module has a high turbidity discharge property, it is possible to apply the direct coagulation membrane filtration process in which membrane filtration is performed without flocculation and sedimentation process. In this paper, it was clarified that the direct coagulation membrane filtration process using the “GL” module has various advantages such as reduction of footprint by saving process, improvement of treated water quality, and high flux by suppressing membrane fouling.
