Peracetic Acid

Peracetic Acid (PAA) is an extremely strong oxidizer, widely used in the food and beverage industry for the disinfection of pipes, cooling water systems, processing equipment and for the spray washing of food products.

What is Peracetic Acid?

Peracetic Acid is an organic compound that is a colourless liquid, characterised by its acrid odour and a very rapid action against all microorganisms.  PAA is often preferred as a disinfecting agent because it produces no harmful breakdown products.

Peracetic Acid is one of the substances used in the early phases of water treatment to destroy bacteria. This chemical does not affect effluent toxicity, therefore doesn’t need to be removed like chlorine. Neither does its use result in toxic residuals, mutagenic, or carcinogenic compounds after disinfection.

Peracetic Acid monitoring

Peracetic Acid is considered environmentally friendly due to its decomposition products, however, it also is highly corrosive and it can severely irritate eyes, skin, and the respiratory system, therefore monitoring is critical.  As with any disinfection system, maintaining proper residual values is the key to effective pathogen control. 

ATi’s accurate, reliable and continuous on-line peracetic acid monitoring solutions are capable of providing real-time measurement of low levels of PAA, helping facilitate reliable chemical feed control for the disinfection system.
