| Title | REMOVAL OF ENDOCRINE DISRUPTER COMPOUNDS FROM MUNICIPAL WASTEWATER USING AN AEROBIC GRANULAR BIOMASS REACTOR |
| Abstract | The removal of selected endocrine disrupter compounds (EDCs), namely estrone (E1), 17-estradiol (E2),
17-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 technology for
biological treatment based on aerobic granular biomass. This new biological treatment is characterized
by high biomass concentration (up to 40 g L-1), 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 both a lab-scale SBBGR system and a demonstrative
unit with a conventional full-scale activated sludge process. Results showed that the SBBGR, beside
its already known benefits (removal efficiencies around 90% COD even at a high organic load (i.e., 5.7 kg
CODm-3 d-1) and a sludge production value of around 0.06 kg TSS kg-1 COD removed), performed better
than a conventional activated sludge process in removing E1, E2, BPA and 4t-OP. The average removal
percentages of the above-mentioned EDCs, obtained during a 4-month operating period, were 60, 69,
93, 81% and 53, 41, 72, 67% for the demonstrative SBBGR system and the conventional activated sludge
process of the municipal sewage treatment plant, respectively. In addition, lab-scale and demonstrative
SBBGR systems showed similar efficiency for the removal of the investigated EDCs. |
