“…One of the main limits of this configuration is the uneven or partial photocatalyst's irradiation. Moreover, the uneven flow distribution also limits the amount of water in contact with the photocatalyst, negatively influencing the overall photoreactor performances Salaices et al, 2001Salaices et al, , 2002Serrano et al, 2010). With respect to the annular photoreactors, a flat plate geometry is scalable, and these types of reactors can be easily used with solar radiation, so they are very attractive and also provide an excellent configuration for efficient excitation of the visible light active photocatalysts (Otálvaro-Marín et al, 2014).…”

“…Experiments were developed in two types of reactors: (a) the Photo-CREC-Water-I reactor, where the catalyst is attached to fiber glass mesh (Serrano and de Lasa, 1997), (b) the Photo-CREC-II reactor, where the catalyst is suspended as a slurry (Salaices et al, 2002).…”

“…Experiments performed using MeB have intrinsic advantages as MeB blue's color disappears as photoconversion progresses and provides a quick assessment of the reactor performance. Additional details about various experimental and analytical techniques are reported in Serrano and de Lasa (1997), Serrano (1998) and Salaices et al (2001Salaices et al ( , 2002.…”

“…for different pollutants [20,21] though the work related to comparison of the different catalysts for the patent blue V dyes is lacking. It is important to establish the optimum loading for the specific dyes so as to avoid the problems of absorption and scattering of incident light by the catalyst.…”

A B S T R A C TThe pollution effects caused by coloured wastewater streams due to the presence of biorefractory dyes are significant, directing the need for a concentrated effort for development of efficient treatment schemes. The present work reports the investigations related to the treatment of patent blue V containing wastewater using modified photocatalytic reactor providing the understanding into the effect of various process parameters and intensification using additives. Comparison of obtained results with natural (solar radiation) and artificial (fluorescent lamp, 11 W) sources confirmed the efficient treatment using the artificial source as expected though significant extent of degradation was also obtained based on the use of solar light. Modifications based on the use of glass coating at the interior of the reactor for possible enhanced utilization of the incident energy showed better degradation efficacy. The removal efficacy was also observed to be dependent on the operating parameters viz. initial concentration and pH with maximum extent of degradation being obtained at initial concentration of 10 ppm and pH of 2.5. Using optimized conditions, the maximum extent of degradation obtained in the present work for different approaches was 86.4% for UV/TiO 2 , 64.7% for solar/TiO 2 , 68.4% for UV/ZnO, 59.0% for solar/ZnO, 92.8% for UV/H 2 O 2 , 72.1% for solar/H 2 O 2 , 81.56% for UV/ferrous sulphate and 66.22% for solar/ferrous sulphate. UV irradiation with modified glass surface photoreactor has been established to be best degradation approach for the removal of patent blue V dye from the wastewater and use of different additives can help in enhancing the extent of degradation. The work has also showed the ways to improve the extent of degradation using solar-based treatment which can be very useful, especially in developing tropical countries like India.
