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

- Calculate the ultimate BOD of a waste that has a measured 5-day BOD of 20 mg/L, assuming aBOD rate coefficient of 0.15/day.arrow_forwardIn 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…arrow_forwardDetermine the volume of wastearrow_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_forwardDescribe the different types of domestic solid waste.arrow_forwardhow is solid and liquid waste similar in recyclingarrow_forward
