Pre- Ozonation for Enhanced Biodegradability

One routing strategy is to use use ozone as a pre- treatment befor e biological filters or constructard wetlands. Ozone partially oxidizes complex organic efficules, breaking them into smaller, more biodegradable compounds. This reduces the load on downstream biological systems andd improves overall removal efficiency. For example, movideides that are normally resistant to microbial degradation mee more metiblie after ozonationation.

Ozonation Followed by Filtration

Ozon causes flocculation of some suspended solids, making them easyr te by sand or message filtration. The combination of ozonation and ultrafiltration can produce water of very high quality, accompleable for drip nawadniation or even potable reuse. Membrane fouling is also reduced becausie ozone breaks organic foulants.

Hybrydowe systemy wigh UV and Hydrogen Peroxide

Advanced oksydation processes (AOP) such as ozone + UV or ozone + hydrogen peroxide generate even more hydroksyl radicals, accelerating the degradation of stubborn difficultants. These hybride systems are more energy- intensive but can accesse mineralization of contaminants. For agricultural runoff containg appeeutical residuees or endocryneing chemicals, ain AOP may bee necesary.
