FILTER MEMBRANE SYSTEM SOLID-LIQUID SEPARATOR AND WASTE WATER TREATMENT EQUIPMENT WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a filter membrane system solid-liquid separator which can efficiently carry out waste water treatment, can lower equipment expenses and operating cost, prevents a decrease in membrane permeation flux due to the formation of scale and slime on the filter membrane in the solid-liquid separator, reduces the frequency of cessation of operation for washing operation and can also lower power cost and to provide a waste water treatment equipment with the solid-liquid separator. SOLUTION: The filter membrane system solid-liquid separator 3 is obtained by disposing a filter membrane unit 10 formed by alternately arranging a plurality of rectangular platelike flat membrane modules 11 and a plurality of hollow fiber membrane modules 12 each comprising a plurality of hollow fiber membranes 13 in the horizontal direction in a solid-liquid separation vessel 3a and further disposing a gas dispersing means 7 under the unit 10 in the vessel 3a.
