Micro plastics havee one of te mest pervasive estates investments in modern water cycles. These plastic fragments than 5 mm originate frem the degradation of larger plastic debris, industrial pellets, synthetic textille fibers, and personalel care products. They are now detectte in oceans, rivers, groundater, tap water, and even bottled water. Ingestion by aquatic organisms leades bioacculation, whums face face risks fron transprisks transprine exposure tregking water.

Primary vs. Secondary Microplastics

Primary microplastics are messared at small sizes - microbeads in cosmetics or industrial abrasives. Secondary microplastics result frem weathering and framentation of larger plastic items, such as bags, bottles, and fishing nets. Both types persist in thee environment for centers, adsorbing toxic chemicals and serving as vectors for patogen.

Conventional Water Treatment Methods for Microplastics

Standard drinking water and waterwater treatment trains trains include coagulation, flocculation, sedimentation, sand filtration, and condite processes like microfiltration and ultrafiltration. These methods can removeve a fational fraction of larger microplastics, but removal efficiency decliens for participles smaller than 10 µm.

Chemistry of Ozone in Water

Ozon (O) is a highly reactive equilule produced by corona discharge or UV irradiation of oksygen. When injecte into water, it rapidly decoposte into hydroksyl radicals (• OH), even more powerful oksydants that attack organic and inorganic conditants non-selectivele.

Despite roote, ozonation is nott a standalone solution for microplastic elimination. Key challenges include:

Combinaing Ozonation wigh Other Treatments for Maximum Efficiency

Ozone + Coagulation / Filtration (Ozone + DAF)

Pre- ozonation enhances the performance of disolved air flotation (DAF) and sand filtration by destabilizing microplastics. Studies show that a short ozone contact time followed by coagulation can double removal rates of polyethylene microspheres compared to coagulation alone.

Ozon + Hydrogen Peroxede (Advanced Oxidation Process - AOP)

Future Directions andInnovations

Photocatalytic Ozonation

Te integration of ozone with photocatalysts undeor visible light aims to accesse nearly-complete degradation of microplastics at lower energy coss. Catalist development focuses on non-toxic, eart- abundant materials like bismuth vanadate.

Conclusion: Ozonation as Part of a Multi- Barrier Approach

Ozonation alone cannot eliminate all microplastics from water, but it s ability to modify particles surfaces, enhance flocculation, and degrade associated chemicals make it a valuable context of modern treatment trains. As research clarifies the optimal condirections for various polymer type andsizes, and as energyent ozone generation logies mature, ozonation will likely meline a standard tool ithe fit against plastic conflutiotion.
