“…At alkaline pH, several studies report an interesting behavior of H 2 O 2 reagent, even when it is used alone. In fact, it has already obtained degradation efficiencies higher than 90% in 60 min regarding dibutylsulfide (DBS) degradation [77], higher DBS disappearance rate for single H 2 O 2 when compared to single ozone or O 3 /H 2 O 2 system for pH < 12 [77], and about 52% of 4-chloro-2 nitrophenol degradation at pH = 10 [78], which showed better results than at pH < 10, with UV use, or in Fenton's (from pH = 6 until pH = 10) [78].…”

Water scarcity represents a problem for billions of people and is expected to get worse in the future. To guarantee people’s water needs, the use of “first-hand water” or the reuse of wastewater must be done. Wastewater treatment and reuse are favorable for this purpose, since first-hand water is scarce and the economic needs for the exploration of this type of water are increasing. In wastewater treatment, it is important to remove contaminants of emerging concern, as well as pathogenic agents. Parabens are used in daily products as preservatives and are detected in different water sources. These compounds are related to different human health problems due to their endocrine-disrupting behavior, as well as several problems in animals. Thus, their removal from water streams is essential to achieve safe reusable water. Advanced Oxidation Processes (AOPs) are considered very promising technologies for wastewater treatment and can be used as alternatives or as complements of the conventional wastewater treatments that are inefficient in the removal of such contaminants. Different AOP technologies such as ozonation, catalytic ozonation, photocatalytic ozonation, Fenton’s, and photocatalysis, among others, have already been used for parabens abatement. This manuscript critically overviews several AOP technologies used in parabens abatement. These treatments were evaluated in terms of ecotoxicological assessment since the resulting by-products of parabens abatement can be more toxic than the parent compounds. The economic aspect was also analyzed to evaluate and compare the considered technologies.

“…However, Scarati et al [28] have noticed that when CuO was used as (catalytic) coating for membranes, then the primary radical species were the superoxide radicals, which however did not lead to the further production of hydroxyl radicals. Although, the superoxide radicals are part of the ozone decomposition mechanism towards the formation of hydroxyl radicals [29,30], it seems that in the aforementioned case the decomposition pathway was different. However, the obtained results were not very promising and the catalytic ozonation with the use of this coated membrane may not be sufficiently effective, when applied for the removal/treatment of micropollutants.…”

Catalytic membrane ozonation is a hybrid process that combines membrane filtration and catalytic ozonation. The membrane deposited with an appropriate solid material acts as catalyst. As a consequence, the catalytic membrane contactor can act simultaneously as contactor (i.e., improving the transfer/dissolution of gaseous ozone into the liquid phase), as well as reactor (i.e., oxidizing the organic compounds). It can be used in water and wastewater treatment limiting the disadvantages of membrane filtration (i.e., lower removal rates of emerging contaminants or fouling occurrence) and ozonation (i.e., selective oxidation, low mineralization rates, or bromate (BrO3−) formation). The catalytic membrane ozonation process can enhance the removal of micropollutants and bacteria, inhibit or decrease the BrO3− formation and additionally, restrict the membrane fouling (i.e., the major/common problem of membranes’ use). Nevertheless, the higher operational cost is the main drawback of these processes.

“…Ozone is a strong oxidizer and effective in controlling sulfide and organic-related odors in wastewater collection and treatment systems [23]. Ozone is widely used alone or as a simple combined oxidant to treat various types of specific contaminants, such as haloacetic acid [24], dibutyl sulfide [25], antibiotics [26], colored and bio-refractory compounds [27], and cyanide [28].…”

A B S T R A C TWastewater treatment for water reuse is one of the main concerns in oil refineries since it can lead to high economic and environmental benefits. This paper deals with treatment of an effluents of Shiraz oil refinery called Slops reservoirs effluent by means of ozone as an advanced oxidation agent. For this purpose, ozone is well dispersed at a dose of 5 g/h and effective transferred concentration of 2335 mg/L using a gas distributor into a semi-batch reactor containing 1 L of the wastewater. In order to determine the efficiency of the treatment, the removal percentage of COD and sulfide was selected as studying parameters. The effects of initial sulfide and COD concentrations, presence of UV light, initial pH, and temperature were investigated on the studying parameters. According to the obtained results, the highest removal rate occurred during the first 30 min reaction time. Also it has been observed that, for the initial sulfide concentration of 350 mg/L and the initial COD concentration of 975 mg/L, the ozonation process after 45 min resulted in 100% sulfide removal under optimum initial pH of 9.4 and optimum temperature of 15˚C and presence of UV light. While at the same conditions, 92% of COD removal has been achieved for 60 min ozonation. Also, water turbidity level significantly reduced during the treatment.
