θ_s = FM/(S_h*X_h)
This formula uses 4 Variables

Variables Used

Hydraulic Retention Time in Seconds - (Measured in Second) - Hydraulic Retention Time in Seconds is referred as the ratio between the reactor volume and the feed flow rate, it represents the average time the cells and substrates stay inside the reactor.
F:M Ratio - (Measured in 1 Per Second) - F:M Ratio refers to the amount of organic matter (food) available to the microorganisms in the system to the amount of microbial biomass present.
Influent Substrate Concentration h - (Measured in Kilogram per Cubic Meter) - Influent Substrate Concentration h refers to the concentration of organic matter or nutrients in the raw wastewater entering a treatment plant.
MLVSS Hydraulic Retention Time - (Measured in Kilogram per Cubic Meter) - MLVSS Hydraulic Retention Time refers to the amount of active microbial biomass, which is crucial for the biological degradation of organic pollutants.

STEP 1: Convert Input(s) to Base Unit

F:M Ratio: 0.2 1 Per Day --> 2.31481481481481E-06 1 Per Second (Check conversion here)
Influent Substrate Concentration h: 50 Milligram per Liter --> 0.05 Kilogram per Cubic Meter (Check conversion here)
MLVSS Hydraulic Retention Time: 0.0065 Milligram per Liter --> 6.5E-06 Kilogram per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

θ_s = FM/(S_h*X_h) --> 2.31481481481481E-06/(0.05*6.5E-06)

Evaluating ... ...

θ_s = 7.12250712250711

STEP 3: Convert Result to Output's Unit

7.12250712250711 Second --> No Conversion Required

FINAL ANSWER

7.12250712250711 ≈ 7.122507 Second <-- Hydraulic Retention Time in Seconds
