(b) In the town of Abesim, it is determined that the per capita waste generation rate is 1.4 kg (3.1 lb) per person per day. The collection is conducted once per week by the municipality. If the density of MSW in a typical trash container is 150 kg/m³, how many 120 L (30 gal) containers would be needed for a family of four? (c) From (b), collection trucks have a capacity of 11.5 m³(15 yd³), which can compact the waste to a density of 420 kg/m³. How many customers can a truck handle in a single run, before departing for the transfer station?
i) The Abesim Stone Works employs six people. Assuming that the density of uncompacted waste is 480 kg/m³? , determine the annual volume of solid waste produced by the stone works assuming a waste generation rate of 1 kg/cap^-1.day.
1. Given the following information calculate VSS inert concentration in the influent of the waste stream. Give: Q = 10,000 m^3/d BOD5 = 200 g/m^3 sBOD5 = 80 g/m^3 COD = 400 g/m^3 sCOD = 150 g COD/m^3 TSS = 100 g/m^3 VSS = 80 g/m^3
The Kumasi landfill serves a population of 253,000. Each week 325 trucks bring a total of 2180 tonnes of MSW to the landfill. Each truck averages two loads per day. The trucks each a capacity of 4.5 tonnes, and operate 5 days per week. (a) How much MSW is generated per person? Give your answer in kg.capta-1.day. (1 tonne = 1000kg). (b) What is the average load (in metric tonnes) in each truck when they at the landfill? At what capacity are the trucks operating? (c) If the density of the waste is 265kg.m-3, what is the volume of the MSW disposed of at the landfill each week?
A sanitary landfill is being designed to handle solid waste generated by the town of Pietro, at a rate of 40 Mg/day. It is expected that the waste will be delivered by compactor truck on a 5 days/week basis. The density as spread is 129 kg/m3. It will be spread in 0.8 meter layers and compacted to 0.3 meters. Assuming 2 such lifts per day and a daily cover of 0.13 meters, box your answer the annual volume of landfill consumed in cubic meters. Ignore the soil volume between the stacks. Answer in two decimal value.Also In your solution Compute also the daily horizontal area covered by the solid waste.
From the following date, estimate the unit waste disposal rate per week for a residentialarea consisting of 1200 homes. The average occupancy is 4 persons per home. Theobservation location is a local transfer station that receives all of the wastes collected fordisposal. The observation period was one week.Data:Number of compactor truck loads = 10Average size of compactor truck = 20 yd3Number of flatbed loads = 6Average flatbed volume = 3 yd3Number of loads from individual residents’ private cars and trucks = 20 Estimatedaverage volume per domestic vehicle = 9 ft3
How many residences can be served? If we have a compactor truck which has a capacity of 30 yd3, each truck makes 3 trips/day 5 days a week, each residence has 3 people and each person produces 4lbs of waste. The density of the compacted waste is 425 lbs/yd3.

Can I get a step by step for the following problem? The Bailey Stone Works employs six people. Assuming that the density of uncompacted waste is 377 kg/m3, determine the annual volume of solid waste produced by the stone works assuming a waste generation rate of 2.60 kg/cap.d.
Calculate the ultimate BOD of a waste that has a measured 5-day BOD of 20 mg/L, assuming aBOD rate coefficient of 0.15/day.
A sanitary landfill has available space of 16.2 hectares at an average depth of 10 m. 765 m3 of solid waste are dumped daily at the landfill 5 days per week. This waste is compacted to twice its delivered density. Draw a mass balance diagram and estimate the expected life of the landfill in years.
