- If 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?An industry discharges 10 mgd of a waste that has a BOD5 of 2000 mg/L. How many pounds of BOD5 are discharged?Calculate the annual volume of solid waste produced assuming the volume rate of generation of 1 kg per capita per day by a six workers. Given that the density of waste is 480 kg per cu. meter in a company?
- Calculate the ultimate BOD of a waste that has a measured BOD5 of 24.6 mg·L-1, assuming a BOD rate coefficient (k) of 0.13 day-1.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/LHow much hydrochloric acid (kg/d) is required to neutralize a waste with 20 mg/L NAOH and a flowrate of 220 L/min?
- If the five-day BOD of a waste is 220mg/L and the ultimate BOD is 320mg/L, what is the rate constant?A.0.142/day B. 0.178/day C. 0.210/day D. 0.233/dayQuestion 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 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
