New generation High rate anaerobic reactor with advance oxidation Anaerobic treatment
Anaerobic treatment is the economic choice for the treatment of sewage and industrial effluents containing organic matter measured as COD.
In an anaerobic reactor, a variety of micro-organisms have to work together to convert organic pollutants into biogas. Biogas contains 50 to 80% methane.
The UASB reactor is the commonly used anaerobic reactor for low and medium strength wastewater. When UASB applied to complex wastewaters containing
insoluble COD contributed by fat and proteins.
Fat content of wastewaters accumulates in the reactor adsorbed on methanogenic sludge and as scum on the gas-liquid interface. Eventually sludge
density is so reduced that catastrophic sludge washout occurs and reactor failure occurs.
BFBR-New Generation high rate anaerobic reactor
♦ An Patented Technology in Technical collaboration with CSIR, Government of India
♦ Overcomes the limitations of the UASB.
♦ These reactors are designed with in-house biological growth and chemical equilibrium anaerobic digestion simulation model.
♦ The key feature of the is the buoyant granular bed filter along with close spacing lamella settler integrally provided with the gas-liquid
separator in the reactor which retains sludge and effluent solids.
♦ The high velocity backflow is created by periodic release of gas accumulated in the reactor, thereby avoiding extra pumping systems and power consumption.
♦ The filter bed is kept free from choking by intermittent inverse fluidization, which back flushes retained solids into the reactor mixed liquor.
♦ Start-up quickly and operate at greater efficiency than other reactors without flocculants or granular sludge.
♦ Improving efficiency of removal and efficiency of methanization of fat and lipids in anaerobic reactors so as to avoid pre-treatment requirements.
♦ Floating fat and scum retained and remixed for complete degradation.
♦ It will provide the performance of an anaerobic membrane bioreactor without the drawbacks of expensive systems and high power costs.
♦ Enhancing volumetric organic loading rate in the anaerobic treatment of complex wastewater.
♦ Improving process efficiency in order to obtain high quality effluent (COD less than 150 mg/l) so as to avoid aerobic post treatment for organic carbon removal.
♦ Improving pathogen removal efficiency in the case of anaerobic sewage treatment.
♦ Reducing chemical costs for pH control in anaerobic reactors.
♦ COD can be reduce upto 80-95%,
♦ Save over all 30-50 % of total power and space in the existing ETP. The potential applications for Effluent
♦ Paper mills
♦ Dairy, Ice cream
♦ Food processing
♦ Tannery & Slaughter houses
♦ Edible oil
♦ Fish mill
♦ Sewage treatment
♦ Pharmaceutical
♦ Organic chemical effluent
