Peracetic acid (PAA) is a highly effective biocide, used in a wide range of applications.  Its uses are continually increasing as standards for disinfection and environmental legislation become more demanding.  

Solvay is a leading global supplier of peracetic acid: flexible, innovative, and responsive to our customers’ demands. 

Solvay manufactures a range of high quality peracetic acid solutions, sold under the trade names PROXITANE® and OXYSTRONG®. 

OXYSTRONG® 15 is a specially formulated 15% peracetic acid product  aimed predominantly at larger industrial applications such as municipal effluent treatment. 

The antimicrobial performance of OXYSTRONG® 15 has been established against a wide range of microorganisms considered to be the most relevant to sewage and effluent under both laboratory and operational conditions.

Concentrations needed will depend on contact time and the level and type of organic and inorganic contamination in the system.


Sewage is disinfected to remove pathogenic species that would be harmful to the population. OXYSTRONG® 15 is a rapidly acting oxidising biocide and as such offers our customers an alternative to traditional disinfectants such as UV and hypochlorite treatments.

OXYSTRONG® 15 is a range of peracetic acid based disinfectants formulated for the control of harmful microorganisms in raw sewage and sewage effluent. It is an equilibrium mixture of peracetic acid, hydrogen peroxide, acetic acid and water. In surface water peracetic acid will be hydrolysed. 

The degradation products formed by hydrolysis are acetic acid and hydrogen peroxide, both of which are easily biodegradable substances.
