The CADoS process is characterised by the separation of cellulose and its subsequent use for the dewatering of sewage sludge. To optimise the process it is important to find out more about the quantity of cellulose brought in with the wastewater during the day.
After a stock-taking exercise by Groningen University (RUG) it emerged that there was no generally used and reliable method for measuring the cellulose. This resulted in RUG (Lena Faust) embarking on the development of a method, in which she succeeded. There is now a reliable method for measuring cellulose in wastewater and sludge. The method uses the enzymatic conversion of cellulose to glucose, which is easily measurable. Pre-treatment of the sample and use of the right enzyme were also part of the development process. More details about the method can be found in the poster presented at the Cellulose Symposium on 19 June 2014: Poster_Cellulose symposium
