BS EN 17183 is an international standard that discusses the characterization of sludges.
BS EN 17183 specifies a method for the determination and evaluation of the sludge (bulk) density. It gives the procedure to determine the density of the liquid and the solid fraction of a suspension.
BS EN 17183 gives technical specifications such as terms, definitions, the principle, interferences, apparatus, test procedures, expression of results, precision, and statement of test reports to evaluate the sludge density.
Note: The method given in BS EN 17183 is also applicable to sludge suspensions from other origins, provided that necessary verifications are done.
BS EN 17183 applicable to sludge suspensions from:
Knowledge of density is critical to most unit operations in both first wastewater treatments that are affected by the difference of density between solid and liquid, for example- sedimentation, floatation, and second sludge management operations that are affected by bulk density, for example- centrifugation, storage, spreading.
BS EN 17183 provides the method to determine the sludge density. It talks about the densities of the dry solids and of the liquid phase allow the sludge origin, as well as its degree of decomposition or stabilization. This helps the user to roughly evaluate the density of the sludge, which could give you useful indications on the soluble substrate concentration and on the presence of other substances lighter than water.
