Disinfection Technologies: How Do You Make the Right Choice?

Choosing the right disinfection technology for wastewater treatment is crucial for meeting regulatory standards and ensuring safety. This article compares various options, including sodium hypochlorite (chlorine), peracetic acid (PAA), ozone, and UV disinfection. Each technology has its pros and cons in terms of effectiveness, safety, dosing levels, unintended effects, cost, and availability. Chlorine offers residual disinfection but can cause corrosion and harmful byproducts. UV and ozone are safe but less effective in turbid water. PAA is effective but expensive and corrosive.

Understanding these factors helps you select the most suitable, safe, and cost-effective disinfection method for a utility or industrial business’s wastewater treatment needs, ensuring compliance and protecting health and the environment. Work with engineers and vendors to design a disinfection system tailored to specific requirements.
