1. A sanitary landfill has available space of 16.2 ha at an average depth of 10 m. Seven hundred sixty-five (765) cubic meters of solid waste are dumped at the site 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.
The landfill volume required for dry solid waste generated by a food factory per year is 400 m3. After drying the wet solid waste from the factory X% of it is recycled, followed by 2.5% diversion for composting and 500 m3 for incineration, before the remainder is sent to the landfill. Using the information given below: Density of dry solid waste = 425 kg/m3 Daily generation of wet solid waste = 1500 kg Moisture content of the wet solid waste = 38% Determine X% and estimate the dimensions of the landfill site if the length:width:depth = 5:4:7. QUESTION 2. Estimate the theoretical amount of slow decomposable solid waste (C20H29O9N) required to produce 65 m3of methane (CH4) using the equation below. Assume a 75% conversion and the density of methane is 0.7167 kg/m3. Use the equation below C20 H 29 O9 N + 9H20 = 11CH4 + 9H20 + NH3 C = 12, N = 14, H =1, O = 16 QUESTION 3.

The landfill volume required for dry solid waste generated by a food factory per year is 300 m3. After drying the wet solid waste from the factory X% of it is recycled, followed by 2.5X% diversion for composting and 400 m3 for incineration, before the remainder is sent to the landfill. Using the information given below: Density of dry solid waste = 460 kg/m3 Daily generation of wet solid waste = 2200 kg Moisture content of the wet solid waste = 32% (ii) Determine X% and estimate the dimensions of the landfill site if the length: width : depth = 6:5:4
How many cubic yard of solid waste can be placed on a regulation soccer field (200 ft × 300 ft) subject to the following constraints and conditions? Slope of all landfill faces = 3 to 1 Covered material will be excavated from the site Neglect cover material requirements Lift height = 10 ft Maximum height of landfill = 20 ft Waste generation rate = 4.1 lb/capita day Community population = 80,000 How many soccer fields would be required per year to dispose of the waste from the community, assuming the in-place specific weight of the waste is 1,000 lb/yd3?
The rate of percolation into a 12-m deep landfill is 248 mm/y. The refuse (i.e., waste) field capacity is 305 mm/m and the moisture content of the refuse is 180 mm/m. Calculate how many years it will take for the moisture front to move through the landfill and produce leachate. Round your answer to one term past the decimal point.
A leachate collection system is being designed for a 10 acre landfill. If the drainage rate through the waste to be collected in the perforated pipe is 1.5 inches/day, determine the expected leachate from the landfill in ft3 /s.
Can I get a thorough step by step for the following question? A sanitary landfill has available space 25 ha at an average depth 12 m. Nine hundred sixty-five (965) cubic meters of solid waste are dumped at the site each day for 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.
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
(ii) 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 has 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?
For the community of 25,000 people, calculate how many years it would take to fill a football field 20 ft. deep, assuming a soil daily cover is used that accounts for 25% of the landfill volume. (Assume appropriate quantities of refuse, densities,
A landfill initially received 10,000 ton /day of waste.this receipt rate increases 10% per year.The landfill is closed at the end of the fourth year.Calculate the yearly gas production for 20 years after opening.What is the peak gas production in m3/year
Question 1 Municipal solid waste is generated within a community from several sources, not just the List and discuss these sources. 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? From (b), collection trucks have a capacity of 11.5 m3(15 yd3), which can compactthe 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? In your community, is waste collection carried out by the municipality or by a privatehauler? Who collects the commercial wastes?
