The current work investigates the intensification process of biological oxidation (BO) a pharmaceutical effluent using ultrasound (US)-based pretreatment methods. US, in combination with chemical oxidants, like hydrogen peroxide (H2O2), Fenton, potassium persulphate (KPS), and peroxone, was used as technique to enhance efficacy BO, BO alone could only bring about 16.67% COD reduction. application US under optimized conditions 70% duty cycle, 120W power, pH 2, at 30 °C temperature resulted 12.3% reduction after 60 min, whereas its oxidants loadings higher 20% for H2O2 (2000 ppm), 23.08% Fenton (1:1 Fe:H2O2), 30.77% + peroxone approach (400 mg/h ozone 2000 ppm H2O2). pretreated samples did not produce any toxic by-products, confirmed by toxicity analysis agar well diffusion method. A cow-dung-based sludge acclimatised specifically use BO. treatment time set 8 h, peroxone-pretreated showed maximum overall 60%, which is three times that observed This clearly demonstrates enhancement biodegradation complex recalcitrant US-based pretreatment.
