How do you calculate equivalent population?
3.4 Population Equivalent To calculate the population equivalent for non-domestic sewage effluent, multiply the number of people using the system by the BOD load (g/day) and divide by 60 (60g is the average BOD load for one person in one day).
What do you mean by population equivalent?
Term. One population equivalent (p.e.) means the organic biodegradable load having a five-day biochemical oxygen demand (BOD5) of 60 g of oxygen per day.
What is the population equivalent factor for BOD?
Explanation: BOD of industrial sewage in kg/day = Population equivalent * Average standard BOD of domestic sewage = 6000*0.08 = 480kg/day.
How do you calculate hydraulic equivalent of a population?
A flow of 100 gallons (378 liters) per day is the hydraulic or flow equivalent to the contribution or flow from one person. Population equivalent = 100 GPCD or gallons per capita per day (378 LPCD or liters per capita per day).
What is population equivalent What are the various dilution factors needed while selecting the treatment process?
3.2. 2 Primary treatment
| Quality parameters (mg/l, except as otherwise indicated) | San Diego |
|---|---|
| Raw wastewater | |
| Biochemical oxygen demand,BOD5 | 184 |
| Total organic carbon | 64.8 |
| Suspended solids | 200 |
What is population equivalent explain its impact on wastewater treatment?
Population equivalent or unit per capita loading, (PE), in waste-water treatment is the number expressing the ratio of the sum of the pollution load produced during 24 hours by industrial facilities and services to the individual pollution load in household sewage produced by one person in the same time.
What is population equivalent and explain its impact on wastewater treatment ques10?
What is population equivalent in waste water treatment?
Population equivalent. Population equivalent or unit per capita loading, (PE), in waste-water treatment is the number expressing the ratio of the sum of the pollution load produced during 24 hours by industrial facilities and services to the individual pollution load in household sewage produced by one person in the same time.
What is the population equivalent of the PE?
The PE is an estimate of the usage made of sewage facilities. It is not a measure of population. For residential areas the population equivalent is calculated as five per dwelling and is a direct measurement of the population in an area.
What does PE mean in wastewater treatment?
Population equivalent, PE. The population equivalent is a reference that describes the specific load of a wastewater treatment plant.
How is population equivalent calculated for commercial buildings?
For residential areas the population equivalent is calculated as five per dwelling and is a direct measurement of the population in an area. However for commercial areas it is calculated from the floor area, which is considered to be proportional to the number of people using a premises during the day.
