floor ceremony creature membrane system test

Drain processing by a/the floatation material


System outline

The test and development (the Ishigaki machine H Co., Ltd. production) of a high efficiency creature membrane 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 material layer (3.0 m`4.0 m)
High efficiency style speed (3.0 m/H`4.0 m/H)

Pilot machine (an/the experiment machine)
cross-section area 1m3
material foamed styrol production, diameter 1.9 m/m , 1.5 m/m
