Wastewater

TL;DR: The occurrence of four anti-inflammatory drugs (diclofenac, ibuprofen, ketoprofen and naproxen), an antiepileptic drug (carbamazepine) and a nervous stimulant (caffeine) in influent and effluent samples from four wastewater treatment plants in Seville was evaluated.

TL;DR: A review of realistic aquaculture waste solids management strategies can be found in this paper, where the main reason for treating solids to be discharged from flow-through systems is to reduce potential negative impacts on the surrounding aquatic environment.

TL;DR: Phylogenetic analysis based on 16S rDNA sequences of the 72 clones developed from the sludge at pH 6.0 shows that 85.7% of the clones were closely affiliated with genus Thermoanaerobacterium in family Thermoanobacteriaceae; the remaining 14.3% were with an uncultured Saccharococcus sp.

TL;DR: If struvite were to be recovered from wastewater treatment plants worldwide, 0.63 million tons of phosphorus (as P(2)O(5)) could be harvested annually, reducing phosphate rock mining by 1.6%.

TL;DR: The results of this investigation showed that the ozonation process is capable of achieving high levels of COD and aromaticity removals at about their natural pH values.
