Concept explainers

Collection Systems

The collection systems form a part of sanitary engineering, which is a sub-branch of civil engineering. It is also known as public health engineering and wastewater engineering. It is a methodology followed to remove and properly dispose of human waste, along with creating systems to provide safe and clean usable water. These measures ensure a hygienic and disease-free community. Sanitary engineering, apart from building sewer disposal units, is also involved in plumbing, fire protection, hydraulics, life safety, environmental protection, information technology, microbiology, pathology, and so on.

Question

A new solid waste landfill site is being designed. The landfill will serve a population of 250,000 residents that generates 1 kg solid waste/day-person. Assume that yard waste makes up 15% of the total waste (by weight), paper makes up 40% of the total waste (by weight), and metals make up 10% of the waste (by weight). The municipality bans the placement of yardwaste in landfills and has a recycling program that collects one half of all discarded metals (the other half of metals goes to the landfill). What is the volume of waste that is discarded by the community every day? Assume a waste density at
the curb of 140 kg/m^3.

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?
A landfill with capacity of 26,220 yd and a maximum height of 20 feet, serves a population of 80,000 persons with a waste generation rate of 4.1 lb/capita/day. If the average final specific weight of the waste placed in the landfill is 1200 lb/yd, estimate the amount as delivered waste (expressed in yd') with an average density of 500 lb/yd', that can be placed in the landfill assuming that 30 % of the original waste will be lost through production of landfill gas
In 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)?\
A landfill initially received 10,000 tons/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/yr.

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)
Assuming waste not recovered all goes to landfills. Determine the total landfill capacity consumed national wide each year. The specific weights of waste at landfill are as follows. Convert your answer to # of football stadiums filled. Area of football stadium = 1.75 x size of a standard football field Depth of filling = 30 ft Waste category Specific weight (kg/m³) Aluminum 2470 Steel and other metals 7100 Glass 2300 Paper and cardboard 570 Wood 450 All others ~700
A city of 223567 residents has a waste generation rate of 0.18 cubic meters per day per resident. Based on studies, 43.7%of the waste will be incinerated and the remainder will be sent to a landfill. Of the total waste that goes to the incinerated, 1203% by volume of waste is generated and must be disposed of the landfill. Please calculate the cost of the landfill to be constructed for this city. Assume the following: Compaction factor of 51% Depth of land is 3.3m Landfill life span is 5 years Landfill cost is $33523 per acre

Do you think that the storage in sanitary landfills is the best way of disposing our solid wastes? Explore this question scientifically, geopolitically, and practically. Do we have better options to replace that technology?
The Tatooine community will landfill plastic along with the inert material and rubber. Assuming that inert material and rubber together account for 54.8% of the remainder waste, determine the volume of the landfill if it is to operate for 24 years. The density of the compacted waste is 895 kg/m³. Recall that the community has a population of 600663 residents and generate 0.7 kg of solid waste per day per person. The main waste fractions are shown in the table below: Waste fraction Food waste Paper Plastic Yard waste Percent (%) 41.1 19.8 13.9 8.4 The remainder of the waste consists of metal, glass, inert material and rubber. Answer: * Om^3 Okm^3 You did not give the correct unit. The volume of the landfill is determined by calculating landfilled portion of the waste, that is the plastic content + the inert and rubber portion of the waste. The correct answer is: 9.51e5 m^3
