Hydraulic Retention Time given Volume Required for Anaerobic Digester Solution

STEP 0: Pre-Calculation Summary

Formula Used

Hydraulic Retention = (Volume/Influent Sludge Flow Rate)
θ_h = (V_T/Q_s)
This formula uses 3 Variables

Variables Used

Hydraulic Retention - (Measured in Second) - Hydraulic Retention is referred as the ratio between the reactor volume and the feed flow rate, represents the average time the cells and substrates stay inside the reactor.
Volume - (Measured in Cubic Meter) - Volume refers to the amount of space that a substance or object occupies or that is enclosed within a container.
Influent Sludge Flow Rate - (Measured in Cubic Meter per Second) - Influent Sludge Flow Rate refers to the rate at which sludge (the semi-solid slurry produced in wastewater treatment) enters a treatment system or specific stage of the treatment process.

STEP 1: Convert Input(s) to Base Unit

Volume: 28800 Cubic Meter --> 28800 Cubic Meter No Conversion Required
Influent Sludge Flow Rate: 2 Cubic Meter per Second --> 2 Cubic Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

θ_h = (V_T/Q_s) --> (28800/2)

Evaluating ... ...

θ_h = 14400

STEP 3: Convert Result to Output's Unit

14400 Second --> No Conversion Required

FINAL ANSWER

14400 Second <-- Hydraulic Retention

What is Hydraulic Retention Time ?

Hydraulic Retention Time (HRT) or t (tau) is a measure of the average length of time that a soluble compound remains in a constructed bioreactor. The volume of the aeration tank divided by the influent flow rate is τ (tau), the hydraulic retention time.

How to Calculate Hydraulic Retention Time given Volume Required for Anaerobic Digester?

Hydraulic Retention Time given Volume Required for Anaerobic Digester calculator uses Hydraulic Retention = (Volume/Influent Sludge Flow Rate) to calculate the Hydraulic Retention, The Hydraulic Retention Time given Volume Required for Anaerobic Digester formula is defined as the average time that the liquid fraction of the feedstock stays in the digester. The HRT is essential for ensuring that the microorganisms have sufficient time to break down the organic matter and produce biogas. Hydraulic Retention is denoted by θ_h symbol.

How to calculate Hydraulic Retention Time given Volume Required for Anaerobic Digester using this online calculator? To use this online calculator for Hydraulic Retention Time given Volume Required for Anaerobic Digester, enter Volume (V_T) & Influent Sludge Flow Rate (Q_s) and hit the calculate button. Here is how the Hydraulic Retention Time given Volume Required for Anaerobic Digester calculation can be explained with given input values -> 14400 = (28800/2).

FAQ

What is Hydraulic Retention Time given Volume Required for Anaerobic Digester?

The Hydraulic Retention Time given Volume Required for Anaerobic Digester formula is defined as the average time that the liquid fraction of the feedstock stays in the digester. The HRT is essential for ensuring that the microorganisms have sufficient time to break down the organic matter and produce biogas and is represented as θ_h = (V_T/Q_s) or Hydraulic Retention = (Volume/Influent Sludge Flow Rate). Volume refers to the amount of space that a substance or object occupies or that is enclosed within a container & Influent Sludge Flow Rate refers to the rate at which sludge (the semi-solid slurry produced in wastewater treatment) enters a treatment system or specific stage of the treatment process.
