Rev Environ Sci Technol 2006, 5:732.Conclusions This quick screening study of 10 STPs of seven various cities confirmed that the general performances of STPs when it comes to BOD, COD and SS removal were ranged amongst 66 to 95 . The performance of UASB reactors at Saharanpur (38 MLD STP), Karnal (40 MLD STP), Vadodara (43 MLD STP) Noida (34 MLD) and Ludhiana (111 MLD STP) were ranged from 55 to 80 for removal of BOD, COD and TSS. This short investigation also highlighted the functionality of distinct post treatment choices presently installed at STP.The DHS as well as the activated sludge course of action wereefficient to remove organics and nitrogen from the UASB effluent. The treated effluent is inKhan et al.
