  • Optimization of removal of colour and organic pollutants from textile wastewater treated with UV/▫$H_2O_2$▫ adopting the Plackett-Burman factorial design [Elektronski vir]
    Fakin, Darinka ; Ojstršek, Alenka
    In the research work presented here, a Plackett-Burman two-level partial factorial design was adopted as a multivariate strategy to determine the optimum UV/H2O2 process conditions for maximizing the ... treatment efficiency of dye-rich textile effluents. The influence of wastewater parameters, i.e. type and concentration of dye (C Dye), 100-300 mg/L; concentration of NaCl (C NaCl), 2.5-3.5 mg/L; and concentration of urea (C Urea), 5-15 mg/L; and the amount of NaOH (C NaOH), 1-2.4 mL/L; as well as the operational parameters, i.e. intensity of UV irradiation (I UV), 1.2-1.4 kW; the amount of H2O2, 0.7-8.3 mL/L; and treatment time (t), 6-30 min; on the colour and the removal of organic pollutants was investigated. After determining seven variables, laboratory-scale experiments were conducted using two synthetically-prepared wastewaters solutions that were polluted with two structurally different reactive dyes and selected chemicals. The assessment of the UV/H2O2 pilot plant's performance was by monitoring the absorbance and total organic carbon in the treated samples. The obtained results showed that the treatment time and dye concentration had a major impact on the reduction of both reactive dyes. At the same time, the amount of urea and the intensity of UV radiation had a notable influence on the organic pollutant reduction.
