Challenges and Future Directions

Managing By- Products and Toxicity

Chemical oxidation can generate intermerates that are more toxic than parent compounds (e.g., brominated disinfection by-products from ozonation of bromide- rich waters). Biological post- treatent mutt be especully designed to Degrade these. Real- time monitoring of toxity (e.g., using bioluminescence assays) can guide process controll.

Optimizing Reaktivní látky

For instance, residual hydrogen peroxide from Fenton process can inhibit bacteria if not quenched. Sequencing batch reactors with timed chemical dosing are being developed to address this.
