“…Elimination of IBP was mainly by biodegradation and elimination of DCF relied on sorption but not biodegradation. Similarly, Kruglova et al [33] detected high biodegradation for IBP and no biodegradation for DCF and carbamazepine in nitrifying activated sludge under 12°C temperature conditions.…”

“…DCF, IBP and NPX contain carboxyl groups belonging to acidic functional groups, which could decrease the surface pH to increase their absorption coefficient [31]. Many studies investigated the degradation of NSAIDs and the results indicated that DCF was much more difficult to remove [16, 32, 33]. Kimura et al [32] found that IBP had higher removal rate than DCF in conventional activated sludge.…”

This study covers three widely detected non-steroidal anti-inflammatory pharmaceuticals (NSAIDs), diclofenac (DCF), ibuprofen (IBP) and naproxen (NPX), as NSAIDs pollutants. The objective is to evaluate the impact of NSAIDs at their environmental concentrations on microbial community assembly and activity. The exposure experiments were conducted under three conditions (5 μg L-1 DCF, 5 μg L-1 DCF+5 μg L-1 IBP and 5 μg L-1 DCF+5 μg L-1 IBP+ 5 μg L-1 NPX) in sequencing batch reactors (SBRs) for 130 days. Removals of COD and NH4+-N were not affected but total nitrogen (TN) removal decreased. IBP and NPX had the high removal efficiencies (79.96% to 85.64%), whereas DCF was more persistent (57.24% to 64.12%). In addition, the decreased removals of TN remained the same under the three conditions (p > 0.05). The results of oxidizing enzyme activities, live cell percentages and extracellular polymeric substances (EPS) indicated that NSAIDs damaged the cell walls or microorganisms and the mixtures of the three NSAIDs increased the toxicity. The increased Shannon-Wiener diversity index suggested that bacterial diversity was increased with the addition of selected NSAIDs. Bacterial ribosomal RNA small subunit (16S) gene sequencing results indicated that Actinobacteria and Bacteroidetes were enriched, while Micropruina and Nakamurella decreased with the addition of NSAIDs. The enrichment of Actinobacteria and Bacteroidetes indicated that both of them might have the ability to degrade NSAIDs and thereby could adapt well with the presence of NSAIDs.

“…Activated sludge contains microorganisms that mineralized TCC radiolabeled in either ring (Gledhill, 1975). Carbamazepine was removed very slowly by nitrifying enrichment cultures (Dawas-Massalha et al, 2014), but was completely stable in nitrifying activated sludge (Kruglova et al, 2014). In both the surface and subsurface-applied aggregates a very significant portion of the [carbonyl-14 C]-CBZ was lost to the atmosphere (Fig.…”

“…Results vary depending on the compound. [25][26][27][28][29] CBZ has been found to be stable during treatment in sludges. Mass losses for the other compounds, atrazine (ATZ), desethylatrazine (DEA), carbamazepine (CBZ) and caffeine (CAF) were not statistically different from 90%.…”

Sewage sludge sorption and desorption measurements were conducted for nine diverse contaminants of varying polarity: caffeine, sulfamethoxazole, carbamazepine, atrazine, estradiol, ethinylestradiol, diclofenac, and, for the first time desethylatrazine and norethindrone. Two types of sorption behaviour were observed. Compounds with a log octanol-water partition coefficient, log Kow, below 3 showed little or no sorption over 48 hours of shaking, while compounds with log Kow over 3 showed 30 to 90% sorption within the first few minutes. After 6 hours of shaking, mass loss through suspected biotransformation became evident for some compounds. At the pH range considered (5.7-6.7), diclofenac (pKa 4.0, log Kow 4.5) was the only compound in which pH dependent sorption could be quantified. The log sewage sludge-water distribution coefficients, log Kd, ranged from 0.2 to 2.9, and, as expected, increased with increasing log Kow of the compound and organic carbon (OC) content of the sewage sludge. A sewage sludge precipitated with alum had a substantially lower Kd values, as well as lower OC content, compared to alum-free sludge. Desorption was studied by sequentially replacing supernatant water. With each water replacement, log Kd values tended to either remain similar (following a linear isotherm) or in some cases increase (following a Freundlich-type isotherm). The length of time required to restore equilibrium increased with each rinsing step. A literature review of reported Kd values compared well with the alum-free sludge data, but not the alum-sludge data. Sewage sludge Kd across the literature appear more consistent with increasing Kow.
