In this review, dairy wastewater- treating anaerobic granular reactors are evaluated. Several reactor system have been constructed for dairy waste water treatment, and many different operational strategies have been developed to maximize methane production. Reactors are compared based on COD removal efficiencies and methane production performance. Among the individual reactor system, the UASB reactor has been wildly preferred for dairy waste water treatment due to its simple construction, ease of operation and high performance.  To browse it, please click at the following link :http://dairyknowledge.in/sites/default/files/anaerobic_granular_reactor_...
