“…In order to comply with the current requirements regarding the discharge of treated effluents, this would guarantee an effective control of effluents. Figure 2 (de Oliveira et al, 2020, Mohapatra et al, 2019 illustrates the development of effective techniques for the advanced treatment of effluents contaminated with particulate matter (EPs). These techniques include physico-chemical and biological processes, such as sand and media filtration, chlorination, advanced oxidation processes, AOPs, adsorption using granular activated carbon, zeolite, or other clay materials, hydrolysis processes, constructed wetland (CW), membrane bioreactors, phytoremediation, and biosorption.…”

The cosmetic industry is a significant contributor to environmental pollution, releasing a wide array of emerging pollutants (EPs) into aquatic ecosystems through its effluents. These EPs, including microplastics, synthetic fragrances, UV filters, and preservatives, originate from various cosmetic products and have been increasingly detected in surface water, municipal wastewater, groundwater, and even drinking water sources. The presence of EPs in these environments poses significant risks to both ecological integrity and human health, necessitating urgent mitigation efforts. This review critically evaluates existing mitigation strategies aimed at reducing the environmental impact of EPs from cosmetic industry effluents. It examines the multifaceted nature of the issue, highlighting the need for comprehensive approaches that encompass regulatory, technological, and collaborative efforts. Regulatory measures are essential for setting standards and enforcing compliance to limit the discharge of harmful chemicals into water bodies. However, technological advancements are equally crucial, with the adoption of advanced treatment processes such as advanced oxidation processes, membrane filtration, adsorption, and biodegradation, offering effective means of removing EPs from effluents. Moreover, raising public awareness about the environmental impact of cosmetic industry effluents is paramount to driving collective action and encouraging consumer demand for eco-friendly products. By implementing and continually refining these mitigation strategies, stakeholders can work towards safeguarding ecosystems and promoting a more sustainable future for generations to come. This comprehensive review provides valuable insights for researchers, policymakers, industry stakeholders, and consumers alike, emphasizing the importance of concerted efforts to address the challenge of emerging pollutants from cosmetic industry effluents.

“…This would ensure an efficient management of effluents developed to comply with the regulations in force on the discharge of treated effluents. In this context, efficient methods for advanced treatment of effluents polluted with EPs are developed, which include physico-chemical and biological processes (sand and media filtration; chlorination; advanced oxidation processes, AOPs; adsorption using granular activated carbon, zeolite or other clay materials; hydrolysis processes; constructed wetland (CW); membrane bioreactors, phytoremediation, biosorption), as illustrated in Figure 7 [93][94][95]. The application of activated sludge process to remove emerging pollutants is usually recommended to reduce high organic loads, but it is not suitable for removing EPs, especially at very low concentrations or traces of pollutants [96].…”

Emerging pollutants (EPs) are chemicals known to cause major impacts on the terrestrial, aquatic life and human health as a result of their chronic and acute toxicity. Although lots of studies on EPs behavior in the aquatic environment are currently available in literature, an urgent requirement exists to complete toxicological studies and develop and implement efficient and ecological methods for their removal. This paper raises some relevant problems related to water environment pollution with EPs, the risks they can generate for aquatic life and humans and opportunities to reduce the effects of pollution by EPs removal. Categories of emerging chemicals of concern in the environment, their sources, fate and impacts, with some examples are discussed. Organic UV filters are shortly presented as a relative new EPs category, with a focus on the need to develop extensive experimental studies on their environmental occurrence, fate and removal. Furthermore, sources for the aquatic environment resulting from discharging EPs directly into rivers from wastewater treatment plants are examined. The incidence of environmental and human health risks related to EPs is also considered. The removal of EPs from the environment as a solution to risk mitigation is addressed, with emphasis on several non-conventional processes involving biological removal of EPs. The paper provides a critical look at the current challenges posed by the presence of emerging pollutants in the aquatic environment, with critical comments and recommendations for further research to reduce the impact of EPs on water and human health and improve the performance of developed methods for their removal.

Continuous Heterogeneous Fenton for Swine Wastewater Treatment: Converting an Industry Waste into a Wastewater Treatment Material

Swine wastewater (SW) was treated using industrial wastes as raw materials in a pre-treatment process (coagulation or adsorption), followed by a continuous heterogeneous Fenton reaction. Before the treatment conducted as a continuous operation, two different batch optimization strategies were evaluated, in which the effects of H2O2 concentration and pH were studied. The results show that using excessive H2O2 results in the same behavior, regardless of whether the pH is 3 or 7.5, while at low H2O2 concentrations, the acidic pH improves the chemical oxygen demand (COD) removal due to a higher solubility of iron. The partial addition of H2O2 after 60 min of the reaction proved to be unbeneficial. Considering other perspectives, a continuous Fenton process using iron filings (IF) as the iron source ([H2O2] = 50 mg/L) was applied after the SW pre-treatment, consisting of adsorption with red mud (RM) or coagulation with poly-diallyldimethylammonium chloride (PDADMAC). The RM adsorption presented higher COD removal and lower toxicity than the PDADMAC coagulation, revealing to be a suitable material for this purpose, but for both pre-treatments, the application of a subsequent continuous Fenton process revealed to be essential to achieve the COD discharge limits imposed by the Portuguese law. In addition, high amounts of dissolved iron were present in the samples (55–58 mg/L) after the Fenton process. However, after the overall treatment, the samples showed no harmful characteristics for Lepidium sativum, being classified as “non-toxic”, contrary to the initial wastewater.
