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.
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.
ENVIRONMENTAL ENGINEERING a). List and describe the main features of the In-vessel Anaerobic Digestion Process for a small pig farm and provide 3 advantages/disadvantages each, of Biodigesters. b). List the typical constraints of a common Landfill and outline the required features of a Sanitary Landfill that is designed to overcome most of the constraints of a common Landfill. c). Estimate the landfill area need to handle one year’s Municipal Solid Waste for a town of 20,000 people, if the per capita national average discard is 3kgs per day, there is no combustion, with a landfill density of 1,000kg/cu.m., and one 4m lift per year. Assume 20 percent of the cell volume is soil used as cover.
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.
Household hazardous wastes are often found in a sanitary landfill in Malaysia. Explain a proper plan on how to stop this issue from being aggravated.
The City of Forty-Five (population 465,565) has requested your assistance in evaluating its solid waste collection system. Determine the mean time per collection stop plus the mean time to reach the next stop, the number of pickup locations per load, and the minimum number of trucks the city must own. The City of Forty-Five collection data are as follows: Average truck capacity = 12.5 m3; Average observed compaction ratio = 2.87 Crew size = 2; Number of pickups = 1 /wk (no rear-of-house service) Average number of cans per stop = 2.63/wk at 0.1136 m3/can Average number of residents per stop = 5 Average uncompacted density = 105.76 kg/m3 Average transport time to disposal site including delays and dumping = 1.78 h/trip Average number of trips to disposal site = 2/d; Rest breaks = 2 at 28.0 min Average maintenance downtime = 37.0 min/d; Average workday = 8.00 h Average percent of trucks out of service for major repairs = 15.0% Number of workday per week = 5
