In 2008, the total solid waste (SW) produced in US is 249.61 million tons (note: metric ton). The SW may be divided into 11 sorts, as shown below. For any particular SW type, Column 1 represents the fraction of the SW type in the total SW, Column 2 shows how many percent of the type of SW was recycled/recovered, Column 3 represents how many percent of the type of SW was combusted, and Column 4 shows the density of the type of SW. The volume of waste residue after combustion was negligible. 1) Usually, SW was compacted by some special equipment before landfilling. Also, because of the gravity from the other SW and cover material that was located above, the SW in a landfill was compressed, more or less. As a result, the volume of SW was decreased. Different sorts of SW exhibit different volume reduction behaviors. Column 5 is compact ratio, indicating the volume reduction. Compaction ratio = Volume before compaction/Volume after compaction. Please compute total volume and the average…

A truck dumped industrial waste into a pit. They found the truck 3 days ago with a pure pool of waste. Your lab finds the BOD5 of this waste to be 80 mg/L with a k=0.1/day. What was the waste source? Here are the 3 nearby suspects: Winery BOD ultimate = 275 mg/L Vinegar manufacturer BOD ultimate = 80 mg/L Pharmaceutical BOD ultimate = 200 mg/L
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
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.
Using the energy content (wet basis) of the waste components given in the table below, calculate the overall energy content of the waste having the composition shown. You can assume 100 lb of waste to make this easier. Then determine the composition of the left-over waste if 80 % of the cardboard, 60% of the yard waste, 50% of the paper, 30 % of the metals and 20% of the plastics are recovered or recycled. How does this affect the total energy content of the discarded waste? How about the energy content per mass (wet weight)?
Can I get a thorough step by step for this question? Each month the speedy dry-cleaning company buys 1.75 barrel (0.28 m') of dry-cleaning fluid. The amount of fluid lost to the atmosphere as emission is 210 kg/month and the remaining remains as residue to be disposed of. The density of the dry-cleaning fluid is 1.5940 g/mL. Draw a mass-balance diagram and estimate the monthly % of mass residue to be dosposed of.
A sample of dry solid waste has the following composition: 531 g carbon (C), 133 g hydrogen (H), and 335 g oxygen (O). How many Litres of air is required to combust the waste? Answer: Check
