A wastewater is incubated for 8 days and the BOD8at 20°C is found ...

The ratio of oxygen available in the wastewater (as dissolved oxygen) to the total oxygen required to satisfy its first state BOD is called relative stability.

Relative stability,

Where, t₂₀ and t₃₇ represent the time in days for a sewage sample to decolorize a standard volume of methylene blue solution, when incubation is done at 20° or 37°C respectively.

S = 100 × 0.842

Similar Civil Engineering (CE) Doubts

A wastewater stream in a city with flow rate 200 m3/s, discharges at a point into a river, which is fully saturated with oxygen and flowing at a rate of 2800 m3/s during the lean period with velocity of 25 cm/s. It was estimated that the critical deficit will occur at a location of 30 km downstream of the river from the point where wastewater starts mixing into river water. If the 5 days BOD of the wastewater at 30°C temperature is 350 mg/l and considering the temperature of the mix to be 20°C, then the critical oxygen deficit (in mg/L) will be _______. It is given that kDand kRat 20°C are 0.10 per day and 0.2 per day respectively. Correct answer is between '13.7,14'. Can you explain this answer?
