Sludge theory
WebbLamella clarifiers can be used in a range of industries, including mining and metal finishing, as well as to treat groundwater, industrial process water and backwash from sand filters. [1] Lamella clarifiers are ideal for applications where the solids loading is variable and the solids sizing is fine. [2] WebbIn order to predict the sludge settling behaviour using the Pitman and White model which adopts the solid flux theory, the settling tests for the determination of settling properties of the sludge (e.g. SSVI and SVI) were performed using a 2 litre graduated cylinder as described below in accordance with Water research council standards.
