Pretreatment of antibiotics-contaminated waste biological sludge by ozonation

Boševski I., (Corresponding) Kalčikova G., Derco J., Žgajnar Gotvajn A.

Topic:

Wastewater treatment

Ozonation was studied as a pretreatment method for a waste biological sludge, contaminated with large amounts of globally used antibiotics; tiamulin, levofloxacin and amoxicillin. At the concentrations of over 100 mg L-1, these antibiotics were found to inhibit biogas production (up to 50%), which...Read more

Investigation of food additives readily biodegradability in respirometric tests

Vazaiou N., (Corresponding) Gatidou G., Arvaniti O., Stasinakis A.

Topic:

Emerging pollutants

The biodegradability of fourteen (14) food additives, belonging to different groups such as artificial sweeteners, preservatives and coloring agents, was evaluated using the OECD 301F protocol (manometric respirometry test). According to the results, seven out of fourteen compounds, namely...Read more
