Tohkemy MBR Unit Water Treatment Systems

Manufacturer: Tohkemy Corporation
Model: MBR Unit

Features

Resolve the problems of the wastewater increase with increased production
Changing to the MBR from the installed sedimentation treatment equipment can correspond to them.
Shorten the treatment time and improve efficiency
Filtration under reduced pressure separates solid and liquid and doesn’t need any time for sedimentation and separation.
Besides standard biological treatment aeration vessel has the MLSS as approx.2,000~3,000mg/L, the MBR vessel can make the high concentrated one as approx.8,000~10,000mg/L, which means the efficient biological treatment possible.
The treatment water quality is as good as to be reused.
The SMF membrane nominal pore diameter is 0.05μm, which makes the turbidity of treated water less than 1 degree.
It doesn’t need for sand filtration as the latter part of treatment.
