Moreover, the data reported in Table 2 indicate that SBBGR was
able to meet the COD limit for discharge into sewer system
(500 mg l1) for any OLR value in the range 0.4e2.6 kgCOD m3 d1.
For OLRs higher than 3 kgCODm3 d1 (i.e., phase 5), this latter limitwas exceeded, indicating that SBBGR is not able to stand such a high
OLR value.
