Up flow Anaerobic Sludge Blanket (UASB)
Up flow Anaerobic Sludge Blanket (UASB) is unit Process used in waste water treatment plant. An UASB Process is used for the removal of COD, BOD.
Process Description :-
Up flow anaerobic sludge blanket (UASB) technology, normally referred to as UASB reactor, is a form of anaerobic digester that is used for wastewater treatment. The UASB reactor is a methanogen (methane-producing) digester that evolved from the anaerobic clarigester. Wastewater flows upwards through the blanket and is processed (degraded) by the anaerobic microorganisms. The upward flow combined with the settling action of gravity suspends the blanket with the aid of flocculants. Hitch only those microorganisms capable of attaching to each other survive and proliferate. Eventually the aggregates form into dense compact biofilms referred to as “granules” Biogas with a high concentration of methane is produced as a by-product, and this may be captured and used as an energy source, to generate electricity for export and to cover its own running power.
Target Impurities :-
- COD
- BOD
Advantages :-
- Producion Of Methane gas
- Low operating cost.
- Sludge generation is very low.
- Supernant comes from UASB is use for Gardening.
- Reduction of High strength BOD & COD can be easily done.
