ADVANTAGES OF OZONE IN WASTEWATER DISINFECTION

Ozone is more effective than chlorine in destroying viruses and bacteria.

The ozonation process utilizes a short contact time (approximately 10 to 30 minutes).

There are no harmful residuals that need to be removed after ozonation because ozone decomposes rapidly.

After ozonation, there is no regrowth of microorganisms, except for those protected by the particulates in the wastewater stream.

Ozone is generated onsite, and thus, there are fewer safety problems associated with shipping and handling.

Ozonation elevates the dissolved oxygen (DO) concentration of the effluent.

The increase in DO can eliminate the need for reaeration and also raise the level of DO in the receiving stream.
