“…Consequently, the influence of pH on photocatalytic reactions is extensively investigated as it governs the reaction dynamics in both dye and inorganic decomposition processes [115]. The pH of solutions affects the surface charge properties of catalysts, consequently exerting an indirect influence on adsorption behavior [116]. According to Abu Bakar et al [85], the ideal pH for the solution is 7, leading to an 82.15% degradation of dye sewage.…”

The efficient degradation of organic pollutants in diverse environmental matrices can be achieved through the synergistic application of piezo‐catalysis and photocatalysis. The focus of this study is on understanding the fundamental principles and mechanisms that govern the collaborative action of piezoelectric and photocatalytic materials. Piezoelectric nanomaterials, under mechanical stress, generate piezo‐potential, which, when coupled with photocatalysts, enhances the generation and separation of charge carriers. The resulting cascade of redox reactions promotes the degradation of a wide spectrum of organic pollutants. The comprehensive investigation involves a variety of experimental techniques, including advanced spectroscopy and microscopy, to elucidate the intricate interplay between mechanical and photoinduced processes. The influence of key parameters, such as material composition, morphology, and external stimuli on the catalytic performance, is systematically explored. This study contributes to the increasing knowledge of environmental remediation and lays the foundation for the development of advanced technologies using piezo and photocatalysis for sustainable pollutant removal.

“…Operational issues that were previously associated with conventional techniques can be resolved with UF technology. Superior divalent ion retention at reduced operating pressure and increased flow at reduced energy usage are further benefits of UF membranes [24]. This research aims to critically analyze a unique treatment system that removes iron, manganese, and ammonium simultaneously and simultaneously from groundwater.…”

In the coming decades, there will be a significant issue with the availability of drinkable water as a result of population growth, present consumption patternsand climate change. This issue will have a similar social impact to rising energy prices.By far the most prevalent and easily accessible source of freshwater is groundwater, which is then followed by lakes, reservoirs, rivers, and wetlands. But it contains minimal amounts of microbiological or chemical pollutants. Simultaneously; There is always ammonia (NH 4+ ), manganese (Mn 2+ ), and ferrous iron (Fe 2+ ) at the same time in the majority of anaerobic groundwater sources as a result of human activity and natural processes,presenting a severe risk to the security of supplies of drinking water.Problems including an unwanted taste, a brown color, pipeline obstructions, and a danger to public health because of the possibility of nervous system harm brought on by high concentrations of Fe 2+ and Mn 2+ in water sources.Consuming high levels of NH 4+ is alsolinked to major health hazards for people, including ionic balance disruption in cells that could cause convulsions. Additionally, the transformation of NH 4+ into cancercausing trihalomethanes and organochlorines is possible. Various techniques have been developed to remove Fe 2+ , Mn 2+ and NH 4+ from sources of drinking water. The use of an ultrafiltration membraneas and its features were believed to have much potential to overcome many of the problems related to ammonia, manganese and iron contamination. Any kind of adsorptive, filtration, membrane bioreactor (MBR) process, and so forth, can be used in conjunction with ultrafiltration to remove the aforementioned contaminants.

Este estudo objetivou realizar uma revisão sistemática de literatura atualizada das principais técnicas físico-químicas utilizadas na remoção de ferro presente em águas subterrâneas, que podem mitigar os problemas ambientais e contribuir para a sustentabilidade. O levantamento bibliográfico contou com o uso de três bases científicas de acesso aberto: Google Acadêmico (GA), Scientific Electronic Library Online (SciELO) e Directory of Open Access Journals (DOAJ). Observou-se que os tratamentos aplicados às águas subterrâneas com teores elevados de ferro têm se desenvolvido através de uma diversificação de técnicas, subsidiadas pelas características da água a ser tratada e das tecnologias disponíveis. A maioria dos estudos experimentais citados garantiu uma remoção superior a 90% do ferro presente na água após a aplicação de seus tratamentos. Concluiu-se que faz necessária a disseminação das técnicas expostas, dado o cenário de expansão da contaminação de ferro em mananciais subterrâneos por atividades antrópicas.
