Websludges and dewatered sludge cake. A theoretical example is presented in Table 4.1 of a 5-year change in available nitrogen from applying a sludge containing 2 percent organic and 1 percent inorganic nitrogen. In the example, the organic nitrogen mineralization rate is 40 percent the first year, and this rate is reduced by 50 percent WebThe density of dewatered cakes ranges from 15% to 40%. The thinner cake is similar to a wet mud, while the latter is a chunky solid. The method of ultimate disposal and economics dictate the degree of moisture reduction necessary. Waste solids production in primary and secondary processing can be estimated using the calculation bleow.
