“…Hembach, Alexander, Hiller, Wieland, and Schwartz (2019) applied ultrafiltration and ozone treatment of hygienically relevant bacteria in municipal wastewater treatment plant and indicated that ultrafiltration had higher removal efficiency for facultative pathogenic bacteria and antibiotic resistance genes than ozone treatment, but the inherent retentate as side products of ultrafiltration might require further attention. Chávez et al (2019) examined the treatability of wastewater from petrochemical and cosmetic manufacture by biological and chemical methods. Results showed that solar photocatalytic ozonation using TiO 2 loaded magnetic activated carbon catalyst effectively removed pollutions from the biologically treated wastewater.…”

“…Both methods achieved comparable removal results for CEC degradation in wastewater samples. Chavez, Gimeno, et al (2019) explored ozone-based AOPs with a TiO 2 -based catalyst to treat wastewater after aerobic biodegradation in a sequential batch reactor. It was found that the combined processes of aerobic biodegradation and solar photocatalytic ozonation were successful for the industrial wastewater treatment.…”

By summarizing 187 relevant research articles published in 2019, the review is focused on the research progress of physicochemical processes for wastewater treatment. This review divides into two sections, physical processes and chemical processes. The physical processes section includes three subsections , that is, adsorption, granular filtration, and dissolved air flotation, whereas the chemical processes section has five subsections , that is, coagulation/flocculation, advanced oxidation processes, electrochemical, capacitive deionization, and ion exchange.

“…The time for a complete oxidation reaction depends, before several variables, on the strength of organic substances [50,51]. In the reaction time experiments, the effects of reaction time were investigated at pH 13.9, 1.5 g/L h O 3 dose and 25°C temperature.…”

Biodiesel wastewaters contain high amounts of oil, methanol, soap and glycerin. These wastewaters pollutant concentrations as chemical oxygen demand (COD), total organic carbon (TOC), glycerin and MeOH are fluctuating in the ranges of 250,000-450,000 mg/L, 54,000-110,000 mg/L, 800-1,500 mg/L, and 6,000-15,000 mg/L, respectively. Biodiesel wastewaters lead to blockage of oil drainage systems and reduction of biological activity in biological treatment systems. The purpose of this study was to treat wastewater by ozonation after the electrocoagulation process as pre-treatment. In the ozonation process, the initial wastewater pH value was 13.9, ozone dose was 1.5g/L h, reaction time was 7 h and reaction temperature was 45°C. As a result of 7 h of ozonation, 98.64% of COD, 97.48% of TOC and 99.37% of MeOH removal efficiencies achieved. With these results, biodiesel waste water can be discharge to into the receiving environment according to standards.
