The occurrence and fate of five acidic drugs (Mefenamic acid, Ibuprofen, Ketoprofen, Diclofenac and Clofibric acid) were analysed in three sewage treatment plants (STP) over 4-7 consecutive days. The results point out that the five substances were persistent in wastewater effluents after municipal wastewater treatment. At the most, half of Mefenamic acid was eliminated. Ibuprofen was well remov...

The presented studies were carried out to get more information about physiological properties of methylotrophic bacteria selected from sewage sludges derived from mechanical and biological sewage treatment plants. All the isolated bacterial strains belonged to facultative methylotrophs. The majority of them utilized glucose, starch and lipids. Moreover, most of them were also found to possess p...

The performance of isolated designed consortia comprising Bacillus pumilus, Brevibacterium sp, and Pseudomonas aeruginosa for the treatment of sewage wastewater in terms of reduction in COD (chemical oxygen demand), BOD (biochemical oxygen demand) MLSS (mixed liquor suspended solids), and TSS (total suspended solids) was studied. Different parameters were optimized (inoculum size, agitation, an...

Huge amounts of waste biosolids are produced from biological processes as waste water treatment, agriculture and food production. The volatile compounds could be utilised as a source for renewable energy in anaerobic processes. However, the anaerobic degradation is slow so that large fermenters are necessary. By ultrasonic disintegration the rate limiting hydrolysis of volatile solids is substi...

The treatment of the sewage sludge produced in the biological treatment plants have increasingly become a serious problem. For this reason, when the reuse and the disposal of the sludge are taken into consideration, the pathogens that the sludge contains should be seriously reduced. In this study, as an alternative to traditional treatment methods for the purpose of pathogen inactivation in sew...

We report here the genome of Pseudomonas putida strain UASWS0946, a highly ammonia-tolerant nitrifying strain isolated from sewage sludge aerobic granules, which displays adequate genetic equipment for soil depollution, sludge treatment, and biological fertilization in agriculture.
