Bioaugmentation of bioreactor systems with pre-cultured bacteria has proven difficult because inoculated bacteria are easily eliminated by predatory eukaryotic-microorganisms. Here, we demonstrated an intermediate thermal treatment was effective for protecting introduced denitrifying bacteria from eukaryotic predators and consequently allowed the inoculated bacteria to survive longer in a denitrification reactor. © 2013 The Society for Biotechnology, Japan.

It relates to a treatment of oil-containing waste water using a membrane biological reactor membrane biological reactor biological reactor (MBR), and it is to provide a new treatment apparatus which is capable of suppressing a reduction in biological treatment activity and suppressing an effect on a separation membrane. Provided is a membrane biological reactor having a biological reaction chamber and a membrane separation chamber, in which the it has a configuration that, within the biological reaction chamber, at least one partition is installed to have a first reaction chamber, a second reaction chamber, and if necessary, an additional reaction chamber so as to form an upflow and downflow flow path, an aeration device and a scum/oil skimmer are installed at least in the first reaction chamber, and a mixture liquid containing activated sludge is withdrawn from the membrane separation chamber and distributed and returned at least to the first reaction chamber and the second reaction chamber.

It is an object of the present invention to provide an electrical deionization apparatus having a novel constitution with excellent deionization efficiency. As means for solving this problem, according to one embodiment of the present invention, there is provided an electrical deionization apparatus having deionization compartments, concentration compartments and electrode compartments partitioned from one another by a plurality of ion exchange membranes between a cathode and an anode, wherein, in the deionization compartments and/or the concentration compartments and/or the electrode compartments, at least one of anion exchange fibrous material layers and cation exchange fibrous material layers are disposed on one another intersecting a water-passing direction.
