“…Advanced oxidation, which uses a combination of ozone with other oxidation agents such as UV radiation, hydrogen peroxide or TiO2, generates reactive intermediates and includes electrochemical mineralisation and solar photocatalysis (Comninellis et al, 2008). This is limited by the radical scavenging capacity of the matrix and can be expensive (Petrović et al, 2003).…”

“…Existing strategies that predict relative removals of herbicides, pesticides, and other organic pollutants by activated carbon or oxidation can be directly applied for the removal of many ECs, but these strategies need to be modified to account for recalcitrant species (Westerhoff et al, 2005). Advanced oxidation and solar photocatalysis have the potential for further development (Comninellis, 2008;Robert and Malato, 2002).…”

This paper provides a review of the types of emerging organic groundwater contaminants (EGCs) which are beginning to be found in the UK. EGCs are compounds being found in groundwater that were previously not detectable or known to be significant and can come from agricultural, urban and rural point sources. EGCs include nanomaterials, pesticides, pharmaceuticals, industrial compounds, personal care products, fragrances, water treatment by-products, flame retardants and surfactants, as well as caffeine and nicotine. Many are relatively small polar molecules which may not be effectively removed by drinking water treatment. Data from the UK Environment Agency's groundwater screening programme for organic pollutants found within the 30 most frequently detected compounds a number of EGCs such as pesticide metabolites, caffeine and DEET. Specific determinands frequently detected include pesticides metabolites, pharmaceuticals including carbamazepine and triclosan, nicotine, food additives and alkyl phosphates. This paper discusses the routes by which these compounds enter groundwater, their toxicity and potential risks to drinking water and the environment. It identifies challenges that need to be met to minimise risk to drinking water and ecosystems.

“…These treatment systems have been shown to efficiently remove compounds that remain in wastewater after secondary treatment, such as: pharmaceuticals, endocrine-disrupting chemicals, iodinated X-ray contrast media and musk fragrances (Huber et al, 2003;Larcher and Yargeau, 2013;McDowell et al, 2005;Nakada et al, 2007;Rodayan et al, 2010;Ternes et al, 2003;Zwiener and Frimmel, 2000). Due to the strong oxidizing power of hydroxyl radicals, AOPs such as photocatalysis, ozonation and photo-Fenton systems are of particular interest for the removal or transformation of contaminants of emerging concern (Akmehmet Balcıoğlu et al, 2003;Boleda et al, 2011;Comninellis et al, 2008;Gogate and Pandit, 2004;Nasuhoglu et al, 2012;Valcárcel et al, 2012).…”

• The ozonation of six drugs of abuse and one human drug metabolite was carried out.• Drug removals vary between 3 and 50% for the ozone doses tested.• The main transformation products of the drugs of abuse were identified.• The most plausible structure of a transformation product of MDMA was elucidated. a b s t r a c t a r t i c l e i n f o In this study amphetamine, methamphetamine, methylenedioxymethamphetamine (MDMA), cocaine (COC), benzoylecgonine (BE), ketamine (KET) and oxycodone (OXY) in wastewater at concentrations of 100 μgL −1 were subjected to ozone to determine their removals as a function of ozone dose and to identify significant oxidation transformation products (OTPs) produced as a result of ozonation. A method based on high resolution mass spectrometry and differential analysis was used to facilitate and accelerate the identification and structural elucidation of the transformation products. The drug removal ranged from 3 to 50% depending on the complexity of the matrix and whether a mixture or individual drugs were ozonated. Both transient and persistent oxidation transformation products were identified for MDMA, COC and OXY and their chemical formulae were determined. Three possible structures of the persistent transformation product of MDMA (OTP-213) with chemical formula C 10 H 16 O 4 N, were determined based on MS n mass spectra and the most plausible structure (OTP-213a) was determined based on the chemistry of ozone. These results indicate that ozone is capable of removing drugs of abuse from wastewater to varying extents and that persistent transformation products are produced as a result of treatment.

“…Recent research has demonstrated that anodic oxidation, often indicated as electrochemical incineration, offers an attractive alternative to traditional routes for treating wastewaters containing toxic and refractory organic pollutants, mainly because of the ease of control and the increase of efficiency provided by the use of electrochemical reactors (Comninellis and Pulgarin, 1993;Comninellis and Nerine, 1995;Comninellis et al, 2008;Scialdone et al, 2008). The best results obtained in this area were achieved using inert electrodes such as SnO 2 -Sb, PbO 2 , and boron doped diamond (BDD).…”

-Industrial wastewater containing non-biodegradable organic pollutants consists of highly toxic effluents whose treatment is necessary due to environmental and economical restrictions. In order to treat these effluents, an electrochemical process using a dimensionally stable anode (DSA ® ) and boron-doped diamond (BDD) electrode was studied. The performance of these electrodes for COD removal from aqueous phenol solution was evaluated in the absence and presence of different chloride concentrations. The results showed that DSA ® could be successfully used to remove COD when high chloride concentration (3035 mg L -1 Cl -) and mild current density are employed (50 mA cm -2 ). On the other hand, the presence of chloride did not have the same significant effect on the COD depletion rate using BDD; however, under mild conditions (50 mA cm -2 , 0.190 m s -1 ), the addition of 607 mg L -1 Cl -improved the COD removal by approximately 52% after 8 hours of electrolysis. The effect of current density (i) and flow velocity (v) were also studied, and it was verified that they have an important role on the process performance, especially when DSA ® is used.
