The presence of emerging contaminants in the aquatic environment and their potential effects on living organisms has become an issue of growing concern. Among emerging contaminants, pharmaceuticals may enter the aquatic environment due to their high consumption and their incomplete removal in conventional municipal wastewater treatment plants (WWTPs). The(More)
BACKGROUND Emerging contaminants (ECs) are commonly derived from industrial wastewater, which is often a consequence of an inadequate treatment of the latter. Improperly pretreated pharmaceutical wastewater could cause difficulties in operations of wastewater treatment plants while incomplete elimination of ECs during the processing might result in their(More)
This study explored the removal of five veterinary pharmaceuticals (VPs) (sulfamethoxazole (SMETOX), trimethoprim (TMP), ciprofloxacin (CIPRO), dexamethasone (DEXA) and febantel (FEBA)) from different water matrices (Milli-Q water, model water, tap water and real pharmaceutical wastewater using four types of nanofiltration (NF) membranes (NF90, NF270, NF(More)
This paper focuses on the investigation of different types of SPE sorbents for the preconcentration of eight veterinary pharmaceuticals from water samples. The pharmaceuticals studied were sulfamethazine, sulfadiazine, sulfaguanidine, trimethoprim, oxytetracycline, enrofloxacin, norfloxacin and penicillin G/procaine. Five different SPE materials (Strata-X,(More)
The production of pharmaceuticals has increased rapidly during the last several decades as they have been used for the health of both humans and animals. Routes of environmental exposure include the release of treated wastewater, the land disposal of livestock manures and municipal biosolids (i.e. sewage sludge), as well as the use of medicated aquaculture(More)
In this paper high-performance liquid chromatography with diode array UV detection (HPLC/DAD) after SPE sample pretreatment for simultaneous analysis of pharmaceuticals from three different classes: enrofloxacin, oxytetracycline and trimethoprim, has been developed, optimised and validated. The chromatographic separation was developed on spiked wellspring(More)
The treatment and reuse of rendering plant wastewater with membrane processes is a poorly investigated area that could result in substantial water savings. Membrane fouling is still the main obstacle when treating secondary effluents (SEs) with high content of effluent organic matter (EfOM). Thus, the optimization of coagulation with ferric(III) chloride(More)
This work addresses the removal of glucocorticosteroids (hydrocortisone, HYDRO; and dexamethasone, DEXA) and anesthetics (procaine, PROCA; and lidocaine, LIDO), from water with commercially available reverse osmosis/nanofiltration (RO/NF) membranes. The RO/NF experiments were of long-run type (24 h) in order to accomplish steady-state and to obtain accurate(More)
Our study details the investigation of real pharmaceutical wastewater (PhWW) treatment. A combination of the Fenton process, sand filtration, ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) was tested. The sample of PhWW was highly polluted, containing high chemical oxygen demand (COD, 25,000 mg·L), total organic carbon (TOC, 4,940(More)
