MF Membrane application for
waster water treatment
(Membrane Bio Reactor : MBR).
Advantages of MBR processMBR system can ・dispenses sedimentation tank by using MF membranes ・diminishes aeration tank by higher MLSS concentration ・discharges treated water without SS and colon bacillus and recycle water ・dissolves bulking problem
