“…Based on 0.08 USD/m 3 , H 2 O 2 concentrations start at 4.5 mg/L, which is lower than the industrially used 6.0 mg/L (Kruithof et al, 2007) concentrations are also shown in Table A4 (see Appendix A), reaching from 3.5 to 70 mg/L of Na 2 S 2 O 8 (Table A4, Appendix A).…”

“…The overall process cost can be therefore calculated by using the following pricing information: Energy 0.085 €/kWh; H 2 O 2 1 €/kg; (Rosenfeldt et al, 2006) and the price of Na 2 S 2 O 8 is 130% more of H 2 O 2 on a weight basis (based on EU and USA prices). This gives an approximate value of 0.08 USD/m 3 for 90% atrazine removal (Kruithof et al, 2007).…”

“…Treatment facilities that have currently incorporated this treatment process including the PWN in the Netherlands and the Aurora Reservoir or Orange Country, CA, USA are using 5-6 mg/L H 2 O 2 and around 0.7 to 0.8 kWh/m 3 water treated (Kruithof et al, 2007;Linden and Rosenfeldt, 2011).

Highlights Cost comparison of UVC/HP and UVC/PS for groundwater treatment.  UVC/PS performed better for atrazine removal in Milli-Q water.  UVC/HP had a better overall performance for the removal of the mixture of contaminants.  Results from the collimated beam apparatus were comparable to the flow-through system.  UVC/PS is economically feasible for special matrices where selective oxidation is required. Graphical Abstract 2 AbstractThis study compared the UVC/S 2 O 8 2-system with the more commonly used AOP in water industry, UVC/H 2 O 2 , and examined whether the first one can be an economically feasible alternative technology. Atrazine and 4 volatile compounds (methyl tert-butyl ether, cisdichlorethen, 1,4-dioxane and 1,1,1-trichloroethane) were chosen as model contaminants because they exhibit different susceptibility to UVC photolysis and AOPs. A collimated beam apparatus was utilized for the majority of the experiments (controlled environment, without mass transfer phenomena), while selected experiments were performed in a flow-through reactor to simulate industrial applications. Initial experiments on the activation of oxidants with a LP lamp indicated that S 2 O 8 2-is photolysed about 2.3 times faster than H 2 O 2 and that the applied treatment times were not sufficient to utilize the majority of the oxidant. The effect of oxidants' concentrations were tested with atrazine alone and in the micropollutants' mixture and it was decided to use 11.8 mg/L S 2 O 8 2-and 14.9 mg/L H 2 O 2 for further testing since is closer to industrial applications and to minimize the residual oxidant concentration. Changes of the matrix composition of the treated water were investigated with the addition of chloride, bicarbonate and humic acids at concentrations relevant to a well-water-sample, the results showed that the system least affected was UVC/H 2 O 2 . Only when bicarbonate was used, UVC/S 2 O 8 2-performed better. Overall, testing these systems with the mixture of micropollutants gave better insights to their efficiency than atrazine alone and UVC/S 2 O 8 2-is recommended for selective oxidation of challenging matrices.

“…These results indicate that for an UV based AOP process, the disinfection due to the presence of OH radicals is very small compared to the damage from the UV irradiation, although for viruses, there may be some oxidative enhancements that can assist disinfection efficacy [75]. Kruithof et al (2007) [77] have studied H 2 O 2 /UV treatment for both primary disinfection and organic contaminant control in DWTPs. They proposed to apply this process before the GAC filtration in order to obtain a removal of residual H 2 O 2 .…”

Overview of the Main Disinfection Processes for Wastewater and Drinking Water Treatment Plants

Abstract:The use of water disinfection as a public health measure reduces the spread of diseases. Various disinfection technologies can be used to meet the pathogen inactivation demand in water. This work is an overview of the main disinfection technologies of wastewater and drinking water that reports for the conventional processes the action mechanism, the possible formation of by-products, the operative conditions, the advantages and disadvantages. For advanced and natural processes the action mechanisms are reported. Advanced technologies are interesting but are still in the research state, while conventional technologies are the most used. There is a tendency, especially in Italy, to use chlorine-based disinfectant, despite in some forms could lead to production of disinfection by-products.
