A certain waste has a BOD5of 170 mg/L and its flow is 2000 cubic meter...
Calculation of population equivalent:
Given:
BOD5 of waste = 170 mg/L
Flow of waste = 2000 cubic meters per day
BOD of domestic sewage = 80 grams/capita/day
To determine the population equivalent of the waste, we need to find the number of individuals that would produce the same amount of BOD as the waste.
Step 1: Convert BOD5 of waste to grams:
Since the BOD5 value is given in milligrams per liter, we need to convert it to grams per liter.
1 gram = 1000 milligrams
BOD5 of waste = 170 mg/L = 170/1000 grams/L = 0.17 grams/L
Step 2: Calculate the BOD load of the waste:
BOD load = BOD5 of waste x Flow of waste
BOD load = 0.17 grams/L x 2000 cubic meters/day
Step 3: Convert BOD of domestic sewage to grams:
Since the BOD value is given in grams per capita per day, we do not need to convert it.
BOD of domestic sewage = 80 grams/capita/day
Step 4: Calculate the population equivalent:
Population equivalent = BOD load / BOD of domestic sewage
Population equivalent = (0.17 grams/L x 2000 cubic meters/day) / 80 grams/capita/day
Population equivalent = (0.17 grams/L x 2000 cubic meters/day) / (80 grams/capita/day)
Population equivalent = (0.17 x 2000) / 80
Population equivalent = 3.4 x 10^3 / 80
Population equivalent = 42.5
Therefore, the population equivalent of the waste is 4250.
Therefore, the correct answer is option 'B' (4250).
Given:
BOD5 of waste = 170 mg/L
Flow of waste = 2000 cubic meters per day
BOD of domestic sewage = 80 grams/capita/day
To determine the population equivalent of the waste, we need to find the number of individuals that would produce the same amount of BOD as the waste.
Step 1: Convert BOD5 of waste to grams:
Since the BOD5 value is given in milligrams per liter, we need to convert it to grams per liter.
1 gram = 1000 milligrams
BOD5 of waste = 170 mg/L = 170/1000 grams/L = 0.17 grams/L
Step 2: Calculate the BOD load of the waste:
BOD load = BOD5 of waste x Flow of waste
BOD load = 0.17 grams/L x 2000 cubic meters/day
Step 3: Convert BOD of domestic sewage to grams:
Since the BOD value is given in grams per capita per day, we do not need to convert it.
BOD of domestic sewage = 80 grams/capita/day
Step 4: Calculate the population equivalent:
Population equivalent = BOD load / BOD of domestic sewage
Population equivalent = (0.17 grams/L x 2000 cubic meters/day) / 80 grams/capita/day
Population equivalent = (0.17 grams/L x 2000 cubic meters/day) / (80 grams/capita/day)
Population equivalent = (0.17 x 2000) / 80
Population equivalent = 3.4 x 10^3 / 80
Population equivalent = 42.5
Therefore, the population equivalent of the waste is 4250.
Therefore, the correct answer is option 'B' (4250).
