“…The UV-based processes are cost-competitive with chlorine to improve the quality of swimming pool water and air [9,51]. The use of UV irradiation in the form of low-pressure UV (LPUV) and medium-pressure UV (MPUV) with and without post-chlorination has been explored by some recent studies [10][11][12]18]. Furthermore, the effect of different doses of UV irradiation was also investigated to control the formation of DBPs [10,12,19].…”

“…Furthermore, the effect of different doses of UV irradiation was also investigated to control the formation of DBPs [10,12,19]. The available research reported the formation of N-DBPs (HANs) with UV irradiation and UV/chlorine [10][11][12][13]19]. …”

“…With this awareness, the demand for alternatives to chlorine disinfection has increased. The alternative methods aimed at improving the quality of swimming pool water are: electrochemically generated mixed oxidants (EGMO) [3,[5][6][7][8], ultraviolet (UV) irradiation [9][10][11][12], UV-based advanced oxidation processes (UV-based AOPs) such as UV/H 2 O 2 [13], ozone (O 3 ) [14][15][16], and ozone-based AOPs such as O 3 /H 2 O 2 and O 3 /UV [17][18][19]. The use of O 3 and UV irradiation for the disinfection of swimming pool water has been adopted in some cases, though together with chlorine for the provision of a residual disinfectant [20].…”

“…Although the comparative analysis of different disinfection methods within studies is available, it has not been done between the studies. For instance, a comparison between chlorination, EGMO and O 3 /chlorine [3,6]; between chlorination and EGMO [5,7,8]; between chlorination, UV irradiation and UV/chlorine [10,37]; between chlorination and UV/chlorine [9,11,12]; between chlorination, UV irradiation, UV/chlorine, UV/H 2 O 2 and UV/H 2 O 2 /chlorine [13]; between chlorination and O 3 /chlorine [14][15][16]38]; between UV irradiation and O 3 /UV [18]; between chlorination, O 3 /chlorine, O 3 /H 2 O 2 /chlorine and O 3 /UV/chlorine [17]; and between chlorination, UV/chlorine, O 3 /chlorine, O 3 /UV and O 3 /UV/chlorine [19]. A comprehensive and critical review of performance and a comparison of all the disinfection methods is lacking.…”

This paper presents a comprehensive and critical comparison of 10 disinfection methods of swimming pool water: chlorination, electrochemically generated mixed oxidants (EGMO), ultraviolet (UV) irradiation, UV/chlorine, UV/hydrogen peroxide (H 2 O 2 ), UV/H 2 O 2 /chlorine, ozone (O 3 )/chlorine, O 3 /H 2 O 2 /chlorine, O 3 /UV and O 3 /UV/chlorine for the formation, control and elimination of potentially toxic disinfection byproducts (DBPs): trihalomethanes (THMs), haloacetic acids (HAAs), haloacetonitriles (HANs), trihaloacetaldehydes (THAs) and chloramines (CAMs). The statistical comparison is carried out using data on 32 swimming pools accumulated from the reviewed studies. The results indicate that O 3 /UV and O 3 /UV/chlorine are the most promising methods, as the concentration of the studied DBPs (THMs and HANs) with these methods was reduced considerably compared with chlorination, EGMO, UV irradiation, UV/chlorine and O 3 /chlorine. However, the concentration of the studied DBPs including HAAs and CAMs remained much higher with O 3 /chlorine compared with the limits set by the WHO for drinking water quality. Moreover, the enhancement in the formation of THMs, HANs and CH with UV/chlorine compared with UV irradiation and the increase in the level of HANs with O 3 /UV/chlorine compared with O 3 /UV indicate the complexity of the combined processes, which should be optimized to control the toxicity and improve the quality of swimming pool water.

“…Liviac et al (2010) and Plewa et al (2012) reported UV treatment for the reduction of genotoxicity and cytotoxicity in chlorinated swimming pool water and drinking water treatment systems. Furthermore, several studies have reported that mediumpressure UV lamps are more efficient than low pressure UV lamps for the photo-degradation of THMs (Kristensen et al, 2010;Zare Afifi and Blatchley, 2016).…”
