ROTARY FLAT MEMBRANE SEPARATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a rotary flat membrane separation device which is so designed as to take as broad an effective membrane area as possible while the deflection of a rotary flat membrane disc by rotation is controlled. SOLUTION: This rotary flat membrane separation device has a plurality of hollow rotary shafts l, each of which has a plurality of rotary flat membrane discs 2 fitted to the shaft 1 at an equal interval, the rotary flat membrane discs 2 fitted to the adjacent rotary shafts 1 being intermeshed with each other at an equal interval. In addition, the device is characterized in that the diameter of a collar 3 fitted between the rotary flat membrane discs 2 mounted on the same rotary shaft 1 is equivalent to 0.18-0.34 of the diameter of the rotary flat membrane disc 2.
