Why you need Kemio

Disinfection and sanitation with peracetic acid

Peracetic acid (PAA) is a relatively expensive sanitizer but is popular due to reduced levels of disinfection by-products (DBP) as it breaks down into food-safe and environmentally friendly residues. PAA is effective in reducing the microbial load of wash water and reducing cross-contamination in food and beverage products.

Unlike other common sanitizers, it is effective at weakly acidic pH levels and its efficacy is not greatly impacted by temperature. The US Food and Drug Administration (FDA) limits concentrations in produce wash water, and the Environmental Protection Agency (EPA) regulates PAA as a general use pesticide.

Kemio

  • Get repeatable and reliable results each time. Kemio minimises user input to deliver consistent results from all operators.
  • Reduce uncertainty of test results by enabling operators to act on clear pass/fail results based on your specification.
  • Kemio is suitable for all users, with clear visual instructions which requires user training. Clear visual instructions guide the user and minimises chances for error.
  • Suitable for all sample types, Kemio is not affected by coloured or turbid samples.
  • Reduce expensive laboratory tests with Kemio spot checks.
  • Measure free chlorine, combined chlorine, total chlorine, chlorine dioxide, chlorite and PAA on one instrument.
  • Personalise your Kemio by adding your unique test and application information to improve traceability and provide a complete dataset.
  • Go paperless and protect your data to meet your compliance requirements. The integrated data log summarises 10,000 results to provide a traceable, auditable dataset.
Why would you use PAA as a sanitizer?

PAA is an effective and quick disinfectant. It targets a vast range of bacteria, funghi, and spores. It also does not cause harmful DBP.

What is the best way to test for PAA?

Accurate in-field measurement of PAA can be done using Kemio Disinfection. This sensor method gives a quick accurate read of the level of PAA in a water sample. Designed specifically for use in  food and beverage applications, Kemio provides repeatable and reliable results to ensure food safety and regulatory compliance.

What level of residual PAA do I have in my system?

This is dependent on the application for which you are using the PAA as a sanitizer. Other factors to consider include the organic matter, the type of produce, and the contact time. Levels can range from as low as 10 mg/L to over 2000 mg/L.

What are the disinfection by products of PAA?

The by-products of PAA are acetic acid and water, neither of which are harmful to the environment or to health.
