“…Two of the three studies had a similar experimental set-up consisting of a 1-L batch reactor, 100 to 500 μg/L initial SMX concentration, and synthetic WW Yu et al 2011), yet vastly different results. This discrepancy might be explained by the use of immobilized cell biocarriers prepared by combining polymer and dry sludge in a 2:1 ratio (2.5 cm diameter) in the study by Yu et al (2011). Without the immobilized cell biocarriers, 24 % SMX was removed overall after 48 h (6.5 % removal due to adsorption in the first 12 h) .…”

Antibiotic compounds, like sulfamethoxazole (SMX), have become a concern in the aquatic environment due to the potential development of antibacterial resistances. Due to extensive consumption, excretion and disposal, SMX has been frequently detected in wastewaters and surface waters. This has led to numerous studies investigating the nature of SMX, with many researchers focusing on the biodegradation and persistence of SMX during wastewater treatment and in the environment. This review provides a summary of recent developments, outlines the discrepancies in observations and results, and demonstrates the need for further research to determine optimal biological removal strategies for SMX and other antibiotics.

“…detected ibuprofen as the most abundant compound in four Spanish WWTPs, where concentration levels ranged from 3.73 to 603 μg/L. Several studies reported that the dominant ibuprofen removal mechanism in biological systems (membrane bioreactors(Abegglen et al, 2009) and immobilized cell processes(Yu et al, 2011)) is biodegradation. Other authors also attribute the high removal of ibuprofen to aerobic biodegradation processes during WW treatment rather than to sorption processes.…”

In this study, a 1200L outdoor pilot scale microalgal photobioreactor (PBR) was used for toilet wastewater (WW) treatment and evaluate its ability to remove pharmaceutically active compounds (PhACs). The PBR was operated at two different hydraulic retention times (HRTs), which were 8 and 12days, during Period I (September-October) and Period II (October-December), respectively. Algal biomass concentrations varied by operating period because of seasonal changes. Nutrients (ammonia, nitrogen and total phosphorous) and chemical oxygen demand (COD) were monitored and efficiently removed in both periods (>80%), attaining the legislation limits. At the theoretical hydraulic steady state in both periods, pharmaceutical removal reached high levels (>48%). Two harvesting techniques were applied to the PBR microalgae effluent. Gravity sedimentation was efficient for biomass removal (>99% in 7min) in Period I when large particles, flocs and aggregates were present. In contrast, a longer sedimentation time was required when biomass was mainly composed of single cells (88% clarification in a 24h in Period II). The second harvesting technique investigated was the co-pelletization of algal biomass with the ligninolytic fungus Trametes versicolor, attaining >98% clarification for Period II biomass once pellets were formed. The novel technology of co-pelletization enabled the complete harvesting of single algae cells from the liquid medium in a sustainable way, which benefits the subsequent use of both biomass and the clarified effluent.

A B S T R A C TSodium thiosulfate-modified activated carbon (TDAC-ST) was prepared from Thalia dealbata, and its ability to remove streptomycin (STM) from aqueous solutions was examined. The surface properties of TDAC-ST and the original carbon (TDAC) were also measured by scanning electron microscopy, N 2 adsorption/desorption isotherms, Fourier transform infrared spectroscopy, and energy dispersive spectroscopy. The results indicated that modification with sodium thiosulfate slightly decreased the carbon's surface area but introduced more functional groups and improved the adsorption ability greatly as compared to the original carbon. The effects of solution pH, initial STM concentration and contact time on adsorption system were also studied. The kinetics data followed the pseudo-second-order kinetics model, and the adsorption isotherms fit the Langmuir isotherm equation quite well, and the maximum adsorption capacity of was 247.65 and 170.84 mg/g for TDAC-ST and TDAC, respectively. The results indicated that sodium thiosulfate modification could greatly enhance the adsorption of STM onto activated carbon, and TDAC-ST was a promising adsorbent for the removal of streptomycin from aqueous solutions.
