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).
A stream carries a flow of 2000 m3/day with TDS concentration of 650 mg/l. At a point, 100 m3/day of industrial wastewater is discharged into the stream with a TDS concentration of 500 mg/l. Find out the resulting TDS concentration in the stream after industrial waste is completely mixed with the stream flow. No accumulation takes place
A waste stream is discharging into a river at a rate of 5 m3/s. Upstream of where the waste stream enters the river, the river has a streamflow of 100 m3/s with a nitrate concentration of 1 mg/L. Downstream of where the waste stream enters, the nitrate concentration has been measured to be 3 mg/L. What is the nitrate concentration in the waste stream? Assume no change in storage in the system.
A wastewater treatment plant is operated at a steady state DO concentration of 1.5 mg/L. If the temperature of the wastewater is measured at 10 °C, a= 0.8 and B = 0.95 and the KLa reported by the aerator manufacturer at 20°C in tap water is 5 hrt, estimate the oxygen uptake rate (in mg/L-min) in the aeration basin. You can assume 0=1.024. If the aerator's oxygen transfer efficiency is 24%, what would be the mass of air (kg) required per hour in a 8500 m³ tank? What volumetric flow rate would you have to supply (m³/hr)? 3.
The discharge from the Renenutet sugar beet plant causes the DO at the critical point to fall to 4.0 mg/L. The Meskhenet Stream has a negligible BOD and the initial deficit after the river and wastewater have mixed is zero. What DO will result if the concentration of the waste(L_w) is reduced by 50%? Assume that the flows remain the same and that the saturation value of DO is 10.83 mg/L in both cases.
Determine leachate generated in a cell in a 12-month period. You may assume that: -Percolation through the cover is 15in -Water consumed by waste decomposition is negligible (Life 1 contains mostly fresh waste) -Water loss as water vapor in landfill gas is negligible (again due to fresh waste) -Initial moisture content in fresh waste = 0.20 -Weight of waste in the lift = 3000 lb/yd² -Weight of cover = 1500 lb/yd² -The following sketch depicts water in and out of a waste lift. Water consumption by waste decomposition PER or leachate from above Water stored in waste Leachate generated Water loss as water vapor in landfill gas

1. A mixture consisting of 30 mL of waste and 270 mL of seeded dilution water has an initial Do of 8.55 mg/L; after 5 days, it has a final DO of 2.40 mg/L. Another bottle containing just the seeded dilution water has an initial DO of 8.75 mg/L and a final DO of 8.53 mg/L. Find the 5-days BOD of the waste.
A waste with a 5-day BOD (BOD)=200mg/L and k = 0.1 day¹ is discharged to a river at a rate of 1 m/s. The river has flow rate of 9 m/s and a background ultimate BOD (Lo) of 2 mg/L upstream of the discharge. (a) Calculate the ultimate BOD (Le) of the waste. (b) Furthermore, assuming instantaneous mixing after discharge, calculate Lo of the river water after it has received the waste. Ans.: (a) Ultimate BOD of wastewater = 508.3 mg/L, (b) Ultimate BOD of river water after discharge of waste-52.63 mg/L.
