A centrifuge dewaters digested sludge from ananaerobic digester. Pertinent performance data are; raw sludge feed rate to the anaerobicdigester = 60,000 lb/day on a dry solids basis, digester suspended solids removalefficiency = 55 percent, suspended solids concentration in digested sludge fed to thecentrifuge = 5.0 percent by weight, centrifuge cake solids concentration = 30 percent byweight, centrifuge solids capture = 90 percent. Sketch a process flow schematic of the system showing both the digester andcentrifuge and all flowing fluid streams, clearly identify the appropriate control surface(s)for mass balance analyses, and then determine;(i) dewatered sludge mass flow rate (lb/day)(ii) centrate flow rate (gal/day)(iii) centrate suspended solids concentration (mg/l).
