Sub and supercritical water oxidation of pharmaceutical wastewater

Hazardous wastes treatment technologies

“…Mylapilli and Reddy (2019) studied the treatment of pharmaceutical waste samples that contained a variety of analgesics, antibiotics, antipyretics, antifungal, β‐blockers and drug intermediates, contributing to overall total organic carbon (TOC) of 2,017 ± 49 mg/L, using supercritical water oxidation technology. A maximum removal efficiency of 80.1% was achieved with excess oxidant at 400°C for 60 min residence time in batch reactor.…”

Chemical waste and allied products

“…A total of 2,017 ± 49 mg/L of total organic carbon (TOC) in a pharmaceutical sample was collected from a pharmaceutical plant by Mylapilli and Reddy (2019). Most of the high TOC content in the sample came from antibiotics, analgesics, antimicrobials, antipyretics, beta‐blockers, and also drug intermediates.…”

Effluent recirculation enables near-complete oxidation of organics during supercritical water oxidation at mild conditions: A proof of principle

“…High-risk organics that have been treated through SCWO are e.g., phenol (Matsumura et al, 2000), aniline (Ma et al, 2012), quinazoline (Gong et al, 2016), quinoline (Angeles-Hern andez et al, 2009), and acrylonitrile (Shin et al, 2009). High-moisture waste, liquid wastes and specific wastewaters of significance for treatment via SCWO comprise e.g., oil-based cutting fluids (Jimenez-Espadafor et al, 2011), landfill leachate (Wang et al, 2011;Gong et al, 2015), industrial and/or sewage sludge (Qian et al, 2019;Yang et al, 2019) (Zou et al, 2013a;Miller et al, 2015) and wastewater from the pharmaceutical or dyeing industry (S€ o güt and Akgün, 2009;Mylapilli and Sivamohan, 2019).…”
