“…Increasing evidences suggest that environmental residues of PPCPs could adversely affect non-target organisms, ecosystem functions, and even human health (Prosser and Sibley 2015;Rosi-Marshall and Royer 2012;Wilkinson et al 2016). Due to their widespread use and bioactive nature, PPCPs are considered as a group of contaminants of emerging concern, and have drawn growing attention over the past decades from the scientific community and the public (Daughton and Ternes 1999;Evgenidou et al 2015).…”

Pharmaceuticals and personal care products (PPCPs) consist of a variety of compounds extensively used for the treatment of human and animal diseases and for health or cosmetic reasons. PPCPs are considered as emerging environmental contaminants due to their ubiquitous presence in the environment and high environmental risks. In wastewater treatment plants using conventional activated sludge processes, many PPCPs cannot be efficiently removed. Therefore, there is an increasing need for more effective and cost-efficiency ways of removing PPCPs while treating wastewater. Algae-based technologies have recently attracted growing attentions for their potential application in wastewater treatment and hazardous contaminant removal, which are advantages in reducing operation cost while generating valuable products and sequestrating greenhouse gases at the same time. This work reviews the up-to date researches to reveal potential toxic effects of PPCPs on algae and algae-bacteria consortia, identify mechanisms involved in PPCP removal, and assess the fate of PPCPs in algae-based treatment systems. Current researches suggest that algae and algae-bacteria consortia have great potentials in PPCP removal but more works are required before algae-based technologies can be implemented in large scales. Knowledge gaps are identified and further research focuses are proposed in this review.

“…They were chosen from the range of levels used in other studies [18,41]. In addition, several studies have detected such concentrations in the influent and effluent of WWTPs [42,43]. A total of 21 experimental runs were performed to investigate the influence of different parameters (i.e., initial pharmaceutical concentration, reaction time and current density) on the removal rate of studied pharmaceuticals (Table 2).…”

Abstract:The continuous release of emerging contaminants (ECs) in the aquatic environment, as a result of the inadequate removal by conventional treatment methods, has prompted research to explore viable solutions to this rising global problem. One promising alternative is the use of electrochemical processes since they represent a simple and highly efficient technology with less footprint. In this paper, the feasibility of treating ECs (i.e., pharmaceuticals) using an intermittent electrocoagulation process, a known electrochemical technology, has been investigated. Diclofenac (DCF), carbamazepine (CBZ) and amoxicillin (AMX) were chosen as being representative of highly consumed drugs that are frequently detected in our water resources and were added in synthetic municipal wastewater. The removal efficiencies of both individual and combined pharmaceuticals were determined under different experimental conditions: hydraulic retention time (HRT) (6, 19 and 38 h), initial concentration (0.01, 4 and 10 mg/L) and intermittent application (5 min ON/20 min OFF) of current density (0.5, 1.15 and 1.8 mA/cm 2 ). Results have shown that these parameters have significant effects on pharmaceutical degradation. Maximum removals (DCF = 90%, CBZ = 70% and AMX = 77%) were obtained at a current density of 0.5 mA/cm 2 , an initial concentration of 10 mg/L and HRT of 38 h.

“…Batch adsorption assays for aqueous solutions of GB, MA and NP at concentrations of 1, 5, 10 and 30 mg L −1 (pH adjusted to 7) were set up in triplicate in 5 L PET plastic containers filled with LECA. A solid to liquid ratio of 1.0 kg L −1 was used in each assay, corresponding to a flooding rate close to 100%.…”

“…The widespread use of pharmaceuticals and the generally inefficient removal of such contaminants by most wastewater treatment plants (WWTPs) are the main reasons for their frequent transformation products which may be more persistent or toxic than the parent compounds if complete mineralization is not attained [2,7,8,11,12].…”
