Fuller’s have been brewing some of Britain’s most popular beers since 1845. Producing over 70,000 litres of beer every day comes with significant water management challenges, and Fullers’ flagship organic product, Honey Dew, stays all natural and chemical free – from the first grain to the last bottle.
Chlorine dioxide is a potent anti-bacterial with the ability to kill even chlorine-resistant pathogens such a cryptosporidium. Despite all of this disinfecting power, it is volatile in nature and produces fewer disinfection-by-products compared to traditional chlorine and bromine.This means once the water has been disinfected, there is a much lower level of oxidising and by-product chemicals left over – perfect for cleaning-in-place applications where a product’s organic status needs to be maintained.
One of the few by-products formed is the oxidised form of chlorine dioxide, chlorite (ClO2 ). Being able to accurately measure chlorite is essential as the Soil Association set an upper limit of 0.5 ppm for water that could potentially come into contact with an organic product.
In order to ensure the organic approval of its product, Fuller’s has turned to the Palintest ChlordioX Plus, which is the only portable instrument with EPA approval for measuring chlorine and chlorite.Using Palintest’s disposable sensor technology, the ChlordioX Plus utilises chronoamperometry which eliminates the interferences typically associated with colorimetric methods.Amperometric methods are traditionally the domain of large laboratory instrumentation which require high levels of user care and maintenance of the electrodes, both of which have been overcome with the ChlordioX Plus, in an instrument a fraction of the size and a fraction of the capital investment.This allows Fuller’s to accurately monitor the quality of its process liquor across its site, without the need transport samples to a lab. This efficiency means the right dosing decisions can be made at the right time and the brewery can keep producing great tasting organic beer.
