The submerged membrane process is more adaptable to variations in raw water quality than the casing membrane and has advantages such as stable processing performance compared to existing water treatment processes and less foot print. However, energy consumption is relatively high compared to existing water treatment, so it is necessary to study how to reduce the maintenance cost. This water treatment system reduces the membrane filtration load by applying pre-treatment of plate settler, improvement of solid-liquid separation and discharge function of sludge, and thus it is possible to reduce the energy consumption of membrane filtration process It was possible. |
