The capability of ozone to reduce the hazardous impact environmentally persistent antibiotic tiamulin in term toxicity reduction and enhancement biodegradability was investigated. Different doses were applied but ozonation not effective enough increase aqueous phase. opposite effect observed anaerobic digestion experiments, where as a pretreatment step antibiotic-contaminated sludge detoxify improves biogas production for 75%. As confirmed by 1H NMR HPLC-HRMS analyses, molecule completely...
Efficiencies of direct ozonation and hydroxyl radical oxidation by Fenton process were compared, aiming to improve biotreatability antibiotics contaminated water (tiamulin, amoxicillin levofloxacin). Biodegradability, COD (chemical oxygen demand) TOC (total organic carbon) measured before after applying oxidative process. It was confirmed that significantly smaller molar dose ozone (1.1 mgO3 / mgatb) against the hydrogen peroxide (17 mgH2O2 mgatb), deliver comparable improvements...
Ozonation was studied as a pretreatment method for waste biological sludge, contaminated with large amounts of globally used antibiotics; tiamulin, levofloxacin and amoxicillin. At the concentrations over 100 mg L-1, these antibiotics were found to inhibit biogas production (up 50%), which means, that molecules would pass anaerobic digestion system unchanged. antibiotics, not only removes inhibitory effects but also improves overall 10% or even more, depending on dose oxidant.
