Summary: This study evaluated a new combined treatment approach by combining ozonation and electrolysis for the mineralization of organic compounds in water. The results showed that the method was most effective for TOC removal in alkaline conditions and significantly enhanced performance compared to ozonation alone in acidic conditions. The initial pH had a more significant effect on TOC removal than current density, but both parameters were relevant. Under optimized conditions, 63% TOC removal was achieved.

Summary: The presence of salts, particularly chloride ions, significantly influences the performance of both conventional and catalytic ozonation processes by affecting the rate and extent of organic compound degradation. This influence is due to scavenging of O-3, transformation of organics to more hydrophobic forms, and inhibition of hydroxyl radicals. Through appropriate choice of catalyst, this effect can be mitigated to some extent.

Summary: Phenolic compounds are common contaminants in industrial effluents. A study developed a combined catalytic microbubble ozonation and biological process for efficient treatment of industrial phenolic wastewater. The FeOx@GAC catalyst showed significantly higher catalytic activity in microbubble ozonation for phenolic wastewater treatment, with an improvement in both TOC removal and phenolic compounds degradation. The study also evaluated different biological treatment processes and found that the combined O-3/FeOx@GAC-MBR process achieved high COD removal and phenolic compounds degradation efficiency.

Summary: The discharge of pollutant-rich wastewater without adequate treatment poses a serious threat to the environment. Catalytic and photocatalytic ozonation using metal ferrite are promising methods for making the treated wastewater reusable. This review summarizes the recent advances in metal ferrite nanoparticle catalysts, exploring their preparation methods, characterization techniques, catalytic mechanisms, and modification strategies. Furthermore, the current applications of metal ferrites as ozone catalysts and the synergistic effect of catalytic and photocatalytic ozonation are discussed. The pollutant removal efficiencies using metal ferrite are 20-40% for non-catalytic ozonation, 80-98% for catalytic ozonation, and 60-80% for photocatalytic ozonation.

Summary: This paper investigated the effect of chloride ion (Cl-) on the degradation of organic compounds. It was found that Cl- affects the degradation by transforming center dot OH to reactive chlorine species (RCS). The competition between organics and Cl- for center dot OH determines their consumption rate, which depends on their concentration and reactivity. The study also showed that Cl center dot had no significant contribution to the degradation of organics, possibly due to its reaction with ozone.

Summary: The complexity of wastewater poses a significant challenge to the successful degradation of pollutants in any wastewater treatment regime. Advanced Oxidation Processes (AOP) have emerged as a promising technique for treating industrial wastewater. However, the high operating cost remains a major obstacle for widespread industrial adoption of AOP. Combining biological processes with AOP can lead to sustainable degradation of toxic pollutants in wastewater, with the help of free radicals and the presence of bio-enzymes and microorganisms. This review discusses various AOP techniques, such as catalytic ozonation, electrochemical oxidation, Sono chemical, and photocatalytic processes, highlighting their potential for wastewater treatment and the production of high value by-products. Further research is needed to analyze the effects of AOP in conjunction with biological processes in real time, considering different concentrations of industrial wastewater, and exploring their potential benefits in achieving Sustainable Development Goals (SDGs).

Summary: Non-thermal plasma (NTP) is a novel oxidation method for water and wastewater treatment, involving the interaction among oxidative species, ultraviolet light, and synthetic organic pollutants (SOPs). Previous reviews have mainly focused on the chemical interaction, performance efficiency, and environmental applications of NTP, neglecting the assessment of energy yield as a crucial determinant. This comprehensive review summarizes recent research findings and compares different systems. Factors influencing NTP oxidation systems, including voltage, frequency, initial pollutant concentration, output power, pH, conductivity, discharge time, and removal efficiency, are discussed. The coupling of NTP with catalytic processes can significantly improve performance and energy yield, with the catalytic NTP technique showing synergistic effects up to 600 times greater.

Summary: This study investigated the contamination levels of toxic metals (TMs) in rice cooked under real conditions by rural households in northern Iran. The levels of arsenic (As) and cadmium (Cd) in the cooking water used in rural households were found to be low, but the levels of As and Cd in both raw and cooked rice posed health risks. Therefore, monitoring the TMs levels in home-cooked rice is essential for a more realistic and important assessment of public health risks.

This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.
