One of the emerging technologies in wastewater treatment is the use of peracetic acid (PAA) as a broad-spectrum biocide used to disinfect wastewater.

While chlorine dominates the U.S. wastewater treatment market, peracetic acid is considered a more environmentally friendly option as it hydrolyzes to acetic acid and hydrogen peroxide in water. This means there is little need to remove or neutralize it before treated water enters waterways. It has an extremely fast reaction time (minutes rather than hours) and leaves no harmful by-products.

While there are other newer options for disinfecting wastewaters, some are expensive conversions and may need to be used in conjunction with PAA to handle difficult effluents during wet or stormy weather.

Alternatively, PAA costs less to convert and because it works quickly and efficiently, smaller treatment plants can get the same level of disinfection without increasing the size of the plant. This is an attractive option for small plants that are maxed out because of population growth.

Peracetic acid is also used in markets such as food safety, industrial cleaners, agriculture-pathogen control, fracking-water disinfection, and algae control.

Finding compatible thread sealants is always a concern with new wastewater technologies, especially those that use harsh chemicals such as acids and oxidizers, as many thread sealants on the market will be eaten away by these chemicals. Fluoramics’ LOX-8 Paste thread sealant is engineered to work with peracetic acid, chlorine and aggressive chemicals.
