Abstract
Artificial sweeteners, which are widely used in modern diets and are persistent and may have negative effects on aquatic ecosystems, such as saccharin (SAC), cyclamate (CYC), aspartame (ASP), acesulfame (ACE), sucralose (SUC), alitame (ALT), neotame (NEO), and neohesperidin dihydrochalcone (NSDH), are being found in wastewater effluents at an increasing rate. In order to address this problem, bio-mitigation studies have shown promise as a method of reducing the harm that wastewater-borne artificial sweeteners do to the environment. This review provides a comprehensive overview of recent advancements in bio-mitigation approaches for artificial sweeteners in wastewater treatment systems. Firstly, the prevalence and persistence of artificial sweeteners in wastewater are discussed, highlighting their widespread occurrence and challenges associated with their removal during conventional wastewater treatment processes. Subsequently, various bio-mitigation strategies are examined, including microbial degradation, phytoremediation, and advanced oxidation processes. Microbial degradation, facilitated by diverse microbial communities, has shown potential for degrading artificial sweeteners into less harmful byproducts. several other techniques like Photocatalytic Degradation, Bank filtration, Granular activated carbon (GAC), advanced oxidation processes, such as ozonation and UV/H2O2 treatment, are explored for their ability to degrade artificial sweeteners into non-toxic compounds.
