移 floor ceremony creature membrane ろ過 system test

Drain processing by a/the floatation ろ material


System outline

The test and development (the Ishigaki machine 工 Co., Ltd. production) of a high efficiency creature membrane ろ過 system
The purpose that improves the problem of the creature membrane processing device of ● established.
(1) the problem of a/the washing system
Remaining quantity adjustment of an/the a. microorganism
Lots of the machine that appoint b. washing water/air quantity,
Washing number control for c. load fluctuation
(2) the correspondence problem to load fluctuation
(3) the anxiety to unattended operation
(4) the difficulty of a/the scale up
○ High efficiency style ろ material layer 厚 (3.0 m〜4.0 m)
○ High efficiency style ろ過 speed (3.0 m/H〜4.0 m/H)

◇ ◇ Pilot machine (an/the experiment machine) ◇ ◇
ろ過 cross-section area 1m3
ろ material foamed styrol production, diameter 1.9 m/m φ, 1.5 m/m φ
ろ material layer 厚 2 m/4 m
