The time after which the town will require a new landfill.
Answer to Problem 2.1P
The time after which town will require a new landfill is
Explanation of Solution
Given:
The population is
The industrial waste produced is
The estimated life of landfill is
Concept used:
Write the expression to calculate the amount of waste generated by the residents per day.
Here, waste generated per capita per day is
Write the expression to calculate the capacity of landfill.
Here, the capacity of landfill is
Write the expression for total waste generated per day.
Here, the total waste generated per day is
Write the expression for life of landfill.
Calculations:
Assume the waste generation rate per-capita is
Calculate the amount of waste generated by the resident per day.
Substitute
Calculate the capacity of landfill.
Substitute
Calculate the total waste generated per day.
Substitute
Calculate the life of the landfill.

- Write briefly about stages of Municipal solid waste process collection in an urban area.arrow_forwardIn a suburban area of a city, the total time dedicated to waste collection is, on average, 100 times greater than the combined average time it takes for each stop's collection and the time it takes to reach the next stop. If a waste collection truck has a compaction ratio of 2 and can transport a maximum of 8 (m3) of compacted solid waste per trip, what is the truck's average load volume for each collection in (L)?\arrow_forwardAn industry wants to locate a chemical plant in your city, they expect to generate 25,000 gal/hr of waste containing 800 mg/L of BOD wastes (reactive) and 15,000 mg/L of inert (non-reactive) materials. The industry wants to recycle 300 gal/min (containing 20 mg/L BOD and 400 mg/L of salts) of discharge (effluent) from the municipal wastewater treatment plant to dilute their waste to 6,000 mg/L of inerts prior to pre-treating the wastes on their own property. If the rate constant for the first order degradation of BOD5 to be 0.75/hr, how big must the reactor be to treat the BOD entering the reactor to 200 mg/L?arrow_forward
- 2. A municipal solid-waste site for a city must be located at Site A or Site B. After sorting, some of the solid wastes will be transported to an electric power plant where it will be used as fuel. Data for the hauling of solid wastes from each site to the power plant are shown in Table below SITE B 3 kilometers P100,000 SITE A Average hauling distance Yearly rental fee for solid - P5,000 waste site Hauling Cost 4 kilometers P1.50 per m - km P1.50 per m - km If the power plant will pay P8.00 per mºof sorted solid waste delivered to the plant, where should the solid-waste site be located? Use the city's viewpoint and assume that 200,000 m3 of wastes will be hauled to the plant for one year only. What site must be selected? Show your computation and defend your answer. (20 points)arrow_forwardIn your community, is waste collection carried out by the municipality or by a private hauler? Who collects the commercial wastes? Define the term; Reusearrow_forwardAccording to the U.S. EPA, what is the current cost per ton for disposal of municipal solid waste in a landfill to the nearest $10/ton? (tipping fee) $ 50/ton $ 70/ton $ 60/ton O $ 40/tonarrow_forward
- Problem 6. A new manufacturing facility is being located in your town. It plans to produce 2,000 m³/day of a wastewater that consists primarily of water and the chemical phenol dissolved in it at a concentration of 5 mg/L. Phenol has a chemical formula of C,H5OH. The company has asked the municipal wastewater treatment to consider treating this industrial waste. Your plant currently treats 30,000 m³/day with an average influent of 350 mg COD/L. a) Estimate the increase in COD loading (kg COD/day) if you accept the industrial waste discharge? b) Estimate the additional amount of oxygen (in kg O2/day) needed to oxidize the phenol at the treatment plant.arrow_forwardIf an industrial plant discharges an effluent with a solids concentrationat a rate of 5000 lb/day, and if each person contributes 0.2 lb/day, what isthe population equivalent of the waste?arrow_forwardThe level of nuclear waste that must be put in put in drums and surrounded by concrete, and put into clay lined landfill sites. a. low level b. none of these c. high level d. intermediate levelarrow_forward
- Can I get a thorough step by step for the following question? The US EPA requires hazardous waste incinerators to meet a standard of 99.99% destruction and removal of organic hazardous constituents injected into the incinerator, which is referred to as "four nines DRE". The efficiency is calculated by measuring the mass flow rate of organic constituents entering the incinerator and the mass flow rate of constituents exiting the incinerator stack, as shown in Figure 1. Draw a mass-balance diagram and determine the allowable quantity of contaminant in the exit stream if the incinerator is burning 1.2000 g/s of hazardous constituents. If the incinerator is 96% efficient in destroying the hazardous constituents, what scrubber efficiency is necessary to meet the EPA standard?arrow_forwardCalculate the area required for a landfill having a projected life of 30 yrs with a 250 000 population providing 2.10 kg per capita per day of waste? Given the density if waste of 472 kg, where in the limitation is that the landfills height do not exceed at 16 m?arrow_forwardChoose the correct answer Which of the following wastes is the most recycled in the United States? A.Car batteries; B.Paper; C. Soda cans; D. Yard wastes Which is the primary disposal method for municipal solid waste in the United States? A. incineration; B. recycling; C. landfill; D. none of the above What is (are) the major environmental concern(s) during landfilling?A.gas production. B. leachate generation. C. A and B. D. neither of A or B. The gases produced from landfills are encouraged to be used as a new energy. Which of the following in the landfill gases is (are) the effective ingredient as an energy source?
