| Title | REMOVAL OF ENDOCRINE DISRUPTER COMPOUNDS FROM MUNICIPAL WASTEWATER BY AN INNOVATIVE BIOLOGICAL TECHNOLOGY |
| Abstract | The removal of selected endocrine disrupter compounds (EDCs), namely estrone(E1),
17b-estradiol (E2), 17a-ethynylestradiol (EE2), bisphenol A (BPA) and 4-tert-octylphenol (4t-OP)
from municipal wastewater was investigated using a sequencing batch biofilter granular reactor
(SBBGR), a new system for biological treatment based on aerobic granular biomass. This new
biological treatment is characterized by high biomass concentration (up to 40 g/L), high sludge
retention times (up to 6 months) and low sludge production (i.e., an order of magnitude lower
than commonly reported for conventional biological technologies). The investigation was carried
out comparing a demonstration SBBGR system with a conventional full-scale activated sludge
process. Results showed that the SBBGR performed better than a conventional activated sludge
process in removing E1, E2, BPA and 4t-OP. In fact, the average removal percentages of the
above mentioned EDCs, obtained during a four month operating period, were 62.2, 68, 91.8,
77.9% and 56.4, 36.3, 71.3, 64.6% for the demonstrative SBBGR system and the conventional
activated sludge process of the municipal sewage treatment plant, respectively |
