Fluidized Bed Bio-Reactors

In Fluidized Bed Reactors, cells are "immobilized" in small particles which move with the fluid. The small particles create a large surface area for cells to stick to and enable a high rate of transfer of oxygen and nutrients to the cells. The fluidized bed reactor is most suitable when a high viscosity substrate solution and a gaseous substrate or product are used in a continuous reaction system. Here also we have four phases in treatment i.e. Preliminary treatment, Primary, Secondary & Tertiary Treatment. Preliminary Treatment In Preliminary treatment removal of contents as Poly-ethenes, Papers, fibres, Vegetable & edible pieces, grits, Oil – grease etc. by bar Screening chambers & Oil-trapping is carried out in the equalization sump. Primary Treatment In the next Primary Treatment stage we go for chemical treatment for adjusting ph and this chemical dosing is optional will depend on the raw water. Secondary Treatment In the secondary Treatment Removal of organic matters suspended solids by Biological treatment, decomposition and Clarifications are carried out with specialized attached growth biological treatment technology. Here the Biological action takes place in aeration tank , tube settlers and the clarified water is passed to chlorine contact tank. Tertiary Treatment In the Tertiary Treatment the water from chlorine dosing tank is allowed to settle in buffer tank. From Buffer tank the water is pumped to sand filter & carbon filters respectively. Features
