About
The Advanced Immobilized Cell Reactor Technology
The
Advanced Immobilized Cell Reactor is a tall column packed
with special activated carbon, patented by a research laboratory
of the Government of India.
Bacteria
is immobilized in the pores of the activated carbon matrix;
dead bacteria are periodically replaced with new ones, in
the pores.
The
Advanced Immobilized Cell Reactor Technology integrates biological
& chemical oxidation in a single reactor. Counter-current
liquid and air streams allow simultaneous oxidation and desorption.
Organics are oxidized by compressed air from bottom.

Why
Proprietary Carbon Matrix Is Used:
Activated
Carbon has a low surface area. Cells are immobilized in both
oxic and anoxic zones of the carbon matrix; thus bacterial
oxidation happens in both zones. With the Activated Carbon,
Catalytic oxidation is facilitated, in addition to bacterial
oxidation.
Why
Cells Are Immobilized:
Immobilization
of cells protects the cells from being washed out with the
effluent. This insures consistent quality of treatment.
Also,
immobilization insures that there is greater cell density
at any flow rate. Thus, the Reactor is able to handle shock
loads.
Cell immobilization leads to greater catalytic stability,
which, in turn, means longer catalyst life.
Immobilization
invests the cells with the ability to tolerate higher concentration
of toxic compounds. This spells better treatment.
