“…Several AOPs have been tested for DCF removal from water/ wastewater including photolysis and UV/H 2 O 2 process [6][7], homogeneous Fenton/photo-Fenton oxidation [2,5], heterogeneous catalytic oxidation with H 2 O 2 [9], etc. However, among the various advanced oxidation technologies proposed for the degradation of DCF the heterogeneous Fenton-based process with goethite catalyst has not yet been investigated.…”

Background: Pharmaceuticals have arisen as emerging environmental pollutants due to their potential impact on humans, animals and microorganisms even at low concentrations. Conventional wastewater treatment plants are known to be ineffective for removal of many pharmaceuticals present in wastewater. Advanced oxidation processes are one of the most promising treatment technologies for degradation of such persistent compounds. The current study was focused on the efficacies of various oxidation processes for degradation of diclofenac (DCF) as one of the most widespread pharmaceuticals.

“…Sang et al [39] determined that a UV pilot-scale treatment applied after RO and NF processes did not contribute significantly to microcontaminant removal. Another bench-scale UV/H 2 O 2 process study performed by Kim et al [65] showed that 90% removal efficiency was reached in 39 of the 42 PhACs found in a WWTP secondary effluent. The UV dose (254 nm) was 923 mJ/cm 2 , and the contact time and H 2 O 2 concentration were 5 min and 7.8 mg/L, respectively.…”

The presence of thousands of microcontaminants in wastewaters and their potential risks has drawn a large attention of the scientific community during the last years. The presence of these contaminants is especially controversial when wastewater is considered for reuse because a large number of microcontaminants are frequently not totally removed by conventional wastewater treatment processes. As a contribution to the knowledge in this field, this chapter focuses on the application of four well-known and widely used technologies to the elimination of microcontaminants. Membranes, activated carbon, ozonation, and advanced oxidation processes (AOPs) are deeply reviewed to assess their efficiency and safety in the elimination of these contaminants from wastewater effluents. A brief description of each technology is presented together with a review of their real application, mostly in wastewater treatment plants (WWTPs). A deep analysis of the found data allows to conclude that the four presented alternatives can be useful for microcontaminant mitigation although none of them seem to be a universal barrier for microcontaminants when used separately. In addition, each technology presents drawbacks which demand further research to be overcome. Depending on the final use of reclaimed water, the treatment may require the combination of several of the studied technologies although that results in an economic impact which cannot be neglected.

“…These include activated carbon (Ternes et al, 2002;Snyder et al, 2007), ozonation (Rosal et al, 2010) (Klavarioti et al, 2009;Liu et al, 2009), chlorine dioxide oxidation (Huber et al, 2005), membrane technologies (Yoon et al, 2006;Snyder et al, 2007), and membrane bioreactors (Kimura et al, 2005;Quintana et al, 2005;Shariati et al, 2010). As an example the anti-inflammatory drug diclofenac has consistently shown to be well photodegraded under UV treatment (Andreozzi et al, 2003;Zhang et al, 2008;Kim et al, 2009). This substance also gets well mineralized under ozonation (Rosal et al, 2010) and chlorine disinfection (Kosma et al, 2010).…”
