Blending of wastes to achieve an optimum C/N ratio. Leaves, with a C/N ratio of 50, are to be blended with waste-activated sludge from a wastewater treatment plant, with a C/N ratio of 6.3. Determine the proportions of each component to achieve a blended C/N ratio of 25. Assume that the following conditions apply: moisture content of sludge = 75%; moisture content of leaves = 50%; nitrogen content of sludge = 5.6%; and nitrogen content of leaves = 0.7%.
