“…In particular, electrochemical oxidation (ELOX) has been extensively investigated for the mineralisation of several organic compounds [47] , [48] . PAR or AMX were degraded, employing EOX using a boron-doped diamond (BDD) anode [14] , achieving good elimination results (>90%) when treating medium-high concentrations, 21-1000 mg L -1 for the paracetamol case [49] , [50] , [51] , [52] , [53] , [54] and 47.5-1455 mg L -1 for the case of amoxicillin [55] , [56] , [57] , [58] , [59] , [60] , [61] , [62] . Regarding dexamethasone and sertraline, very few studies reported their degradation with ELOX so far, or with different ELOX-combined treatments, even so achieving good results in terms of degradation, >70% [63] , [64] , [65] , [66] , [67] , [68] , [69] .…”

“…Combined technologies, sometimes called hybrid processes, have also been developed in order to improve removal capacities. In wastewater, amoxicillin elimination has been investigated for a combination of ultrasound and ozone oxidation [26], combined Fenton process [27,28], adsorption and ozone oxidation [29], electrocoagulation as single or in combined processes has been applied to the amoxicillin removal [30][31][32][33], but never coupled to a membrane separation. "Energy consumption of nanofiltration processes is deleteriously impacted by the unavoidable membrane fouling [34].…”

The present study deals with the treatment of an artificial pharmaceutical waste which contained amoxicillin (AMX) by using successively an electrocoagulation (EC) with Ca(NO3)2 as an electrolyte and a nanofiltration (NF) with a Nanomax-50 membrane. The effect of the current intensity and of the operating pressure was investigated for separately EC and NF, respectively. The AMX removal as a function of pH and initial AMX concentration was also investigated for the separately conducted EC and NF processes. The best percentage removal of AMX by EC and NF was recorded to be 52.7% and 99.0%, respectively. In the case of the sequential processes EC followed by NF, the removal of AMX was 98.2% and J o u r n a l P r e -p r o o f 97.5% at pH 2.5 and 10, respectively. The contribution of both EC and NF towards the AMX removal efficiency in the case of the sequential process was very much significant. It is remarkable that the EC pre-treated feed into NF was explored with several benefits such as high removal efficiency, calcium involved in EC process, prolonged membrane life and reduced power consumption. The electrogenerated solids (the sediment and the cathode deposit) were characterized using Fourier Transform Infra-red spectroscopy (FTIR), Energy Dispersive Spectroscopy (EDS) coupled to Scanning Electron Microscopy (SEM), X-ray Photoelectron Spectroscopy (XPS) and Thermo Gravimetry Analysis (TGA). It appeared that calcium was involved in the electrogenerated solids. It gave a cathode deposit of Ca(OH)2 in which some AMX was embedded.

“…Concerning most commonly used technologies of activated sludge, biotransformation is shown as an essential but insufficient step in the removal of hormones and antibiotics [11]. There have been many attempts to regulate both treatment and emission of these substances, however, they have received little attention in most countries around the world [12]. The US Environmental Protection Agency (USEPA) and the European Union has included some medicines in its list of contaminant and monitored substances [13][14].…”

Contaminants removal from industrial effluent is a major environmental concern. In this context, Algestone Acetophenide and Estradiol Enanthate are synthetic sex hormones widely used in the manufacture of contraceptives, whose presence in waterbodies may lead to environmental hazard. Given that so far, the methods employed in the removal of these drugs have presented limited efficiency or high implementation costs, the present work presented an electrochemical reactor composed by 32 carbon steel electrodes (1728 cm 2), which was employed in a real scale model to remove these synthetic hormones in an industrial pharmaceutical effluent. After 60 minutes the removal efficiency of the hormones Algestone Acetophenide and Estradiol Enanthate was of 88.9% and of 91.8% respectively, with low energy consumption (< 0.742 kWh.m-3). Physicochemical parameters such as color, turbidity, Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) also showed good removal efficiency too (> 50%), which implicates that the method herein depicted may be a valuable alternative to promote the removal of these contaminants in industrial wastewater.
