“…The objective was only to check the order of removal to be compared to the further chemical oxidation process. In any case, it can be highlighted that previous works report adsorption as the main way of pharmaceutical removal from urban wastewater [25][26][27][28][29][30]. In Figure 5, on the other hand, the changes observed on TOC with time corresponding to the experiment of Figure 4 are presented.…”

Removal of nine pharmaceutical compounds: acetaminophen, AAF, antipyrine, ANT, caffeine, CAF, carbamazepine, CRB, diclofenac, DCF, hydrochlorothiazide, HCT, ketorolac, KET, metoprolol, MET and sulfamethoxazole, SMX, spiked in a primary sedimentation effluent of a municipal wastewater has been studied with sequential aerobic biological and ozone advanced oxidation systems. Ozone, UVA or Fe(III) during photocatalytic ozonations also allowed mineralization increases, compared to the single ozonation process, from 13% to about 35%. Biodegradability of the treated wastewater increased 50% in the biological process and other 150% after the ozonation processes. Both untreated and treated wastewater was non toxic for Daphnia Magna except when Fe(III) was used in photocatalytic ozonation. In this case, the ferryoxalate formed seems to be the reason of toxicity. Kinetic information on ozone processes reveals that pharmaceuticals at the very low concentrations they are found in urban wastewater are mainly removed through free radical oxidation.2

“…Conventional wastewater treatments for pharmaceuticals are ineffective in eliminating and/or degrading most of these compounds. Therefore, residual quantities remain in the treated water, and have been found to accumulate in drinking water 3,4 . Particularly, paracetamol is one of the pharmaceuticals of common use worldwide due to its effectiveness in the relief of pain and fever.…”

Activated carbon of dende coconut mesocarp was used to investigate the removal of paracetamol from water by adsorption. The results indicated that the retention of paracetamol was favored in activated carbon with neutral surface properties. The textural features and presence of a transport pores network contri buted to ensuring the accessibility to the inner porosity, and the microporosity must be large enough to accommodate the paracetamol molecule. Chemisorption and mainly physisorption are important in the paracetamol removal. Pseudo-second order equation and Langmuir model were chosen to best present the experimental data. The adsorption process was non-spontaneous and endothermic with increase in system dis order.

“…In this respect, biological or biotreatment of wastewater is a better option. The most common biological wastewater treatment applied in the treatment of municipal and industrial wastewaters is the use of activated sludge alone (Nyholm et al 1996;Radjenovic et al 2009) or in combination with algae (Gonzalez et al 2008;Su et al 2012a). However, problems related to dewatering and disposal of sludge have made researchers look for other alternatives.…”

Discharge of untreated domestic and industrial wastewater into aquatic bodies is posing a serious eutrophication threat, leading to a slow degradation of the water resources. A number of physical, chemical and biological methods have been developed for the treatment of wastewaters; among these, the use of microalgae is considered as a more eco-friendly and economical approaches. Microalgae are versatile organisms which perform multiple roles in the environment-bioremediation of wastewater, gleaning of excess nutrients and in turn, generate valuable biomass which finds applications in the food, biofuel and pharmaceutical industries. They are currently being utilized to reduce the high nutrient load (especially N and P) from wastewaters, which fulfill the growth requirements of microalgae, making it a suitable cultivation medium for biomass production. The present review represents a comprehensive compilation of reports on microalgal diversity of wastewaters, followed by a critical overview of their utilization, suitability and potential in bioremediation vis-a-vis biomass production. This review also emphasizes the superiority of polyalgal and consortial approaches in wastewater treatment, as compared to the use of unialgal inocula, besides providing useful pointers for future research needs in this area.
