The results show that starting from a 4-CP initial concentration from 100 to 500 mg L-1 and using an ozone flow rate of 5.44 and 7.57 g h-1, 4-CP was completely removed. A kinetic constant around 9·10-2 min-1 was calculated for the ozone direct attack. The biodegradability (BOD5/COD) of the pre-ozonated solutions increased from 0 until a range between 0.2-0.37. The combination of the ozonation and aerobic biological treatment in an aerobic sequencing batch biofilm reactor (SBBR) gave an abatement of more than 90% of the initial TOC.", pages = "447-455(9)", url = "http://www.ingentaconnect.com/content/tandf/bose/2008/00000030/00000006/art00010" doi = "doi:10.1080/01919510802488037" }
