Which disinfectant is known to be non-toxic to aquatic organisms, a good viricide, and adds oxygen to treated wastewater?

Ozone is recognized for its unique properties that make it particularly effective in wastewater treatment. It acts as a strong oxidizer and has the ability to effectively eliminate a wide range of viruses, which categorizes it as a good viricide. This quality is essential for ensuring that treated water is safe for discharge into the environment or for reuse.

Another significant benefit of using ozone is its non-toxic nature to aquatic organisms. Many conventional disinfectants can be harmful to aquatic life when they are released into the environment after treatment. However, ozone decomposes rapidly into oxygen, minimizing the risk to surrounding ecosystems, making it a more environmentally friendly choice.

Additionally, the decomposition of ozone not only contributes to the removal of pathogens but also results in an increase in dissolved oxygen in treated wastewater. This addition of oxygen can be beneficial for aquatic systems, supporting the health of the water body into which the effluent is discharged.

These properties make ozone an advantageous disinfectant in terms of both effectiveness and environmental safety in wastewater treatment processes.
