Parametric variation effect on sonolysis and photolysis of NBB dye was studied.
Fe doped TiO2 catalyst (with varying ratios) was synthesized using ultrasound.
Sonophotocatalytic treatment enhanced dye color removal of 96% with 2.2 g/L Fe-TiO2.
Sonophotocatalytic treatment of real textile effluent removed color and TOC (91%).
