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.
