MOVING MEDIA BIO REACTOR TECHNOLOGY
Ref: Schedule of Rates MJP Pune Region 2012-2013
The Moving Media Bio Reactor Technology is a advanced biological treatment process which has a
combination of activated sludge process and attached growth process. The bio reactor has lot of packing material
called carrier media in suspension and provides a large surface area for micro organisms to grow and degrade the
organic matter in aerobic condition. Due to the use of carrier media, the higher concentration of bio mass is developed
which helps to reduce the basin size, accept higher loading rates and take shock loads.
The sewage after screening and grit removal flows by gravity into the BIO REACTOR wherein the attached
growth, aerobic microbes will utilize pollutant in presence of oxygen thereby, further reducing BOD. The air required
will be provided through coarse bubble air diffusers provided on the aeration grid at the bottom of reactor and using
positive displacement, twin lobe, root type air blower for supply of oxygen.
The PP media is provided in the aeration tank to allow the aerobic microbes to grow and get attached. This
media remains in fluid state in the aeration tank thereby keeping large number of microbial colonies moving in
the tank and provide high concentration of bio mass available at all the time. The microbes get exposed to bio degradable
organics in presence of oxygen and convert it into cell biomass, water molecule and carbon-dioxide. The
microbial colony grows on plastic media. The excess bio mass gets sloughed and moves with treated water
into subsequent unit. This sloughing action is a continuous process and the microbes keep on growing and
sloughing. This is a very fast process and hence system becomes self sustaining.
The dead bio mass generated will be separated in the CLARISETTLER TANK wherein tube media is provided for providing additional surface area for settlement of bio mass and thereby reducing the space requirement. The solid-liquid separation is achieved in this tank and clear supernatant will flow by gravity
The treated wastewater will be disinfected with Chlorine and allowed to react in CHLORINE CONTACT TANK
prior to suitable disposal.
