In the four configurations of Fig. 4, the internal -i.e. nitrate- recycle from the aerobic zone vanishes. Thus, the anaerobic character of the first zone increases and so do the P release. Optimal solutions for A2/0 and 5-stages Bardenpho process configurations are the same (the differences observed are due to numerical aspects) since the internal recycles vanish they present a zone (P and 2 reactors) with anoxic conditions followed by a zone (3 and 4 reactors) with anaerobic conditions, and finally an alternate aerated zone. The external C source is added to the anaerobic zone (reactor 3). In VIP and modified UCT configurations the sludge recycle is directed to... [Pg.167]

The poor settling of the sludge in the secondary settling tank causes Xy to be lower, which requires a higher sludge recycle ratio to maintain the same mixed liquor concentration in the aeration tank. [Pg.16]

The design of an activated sludge system requires the determination of the following items aeration tank volume V, oxygen requirement, daily sludge wasting rate, and sludge recycle rate R. [Pg.19]
