What is Active Wet Well?
Sewage treatment system in which wastewater is stored in large tank or well before treating is called as Active Wet Well.
In active wet well the term ‘active’ means the water in the well is constantly being mixed and aerated. It is done to break down the large waste particles present in the waste water which will make the process easier for further treatment. On the other hand ‘wet’ term indicates that the well is filled with water.
The main purpose of active wet well is to store the wastewater so that it can be efficiently treated before transporting it to next step of sewage treatment. This helps remove solids, break down organic matter and prepare the water for disinfection and final disposal or reuse.
How to Use Active Wet Well Calculator
- To use the active wet well volume calculator, you need to know the pumping rate of the wastewater and the fill-and-drain cycle time of the well.
- Input these data into the calculator in the respective units.
- Once you input the values, the calculator will automatically display the volume of the Active Wet Well.
What is the Formula to Calculate the Volume of Active Wet Well?
- Volume is the total volume of the Active Wet Well (in gallons)
- Pump Rate is the rate at which wastewater is pumped into or out of the well (in gallons per minute or cubic feet per minute)
- Cycle Time is the duration of one complete fill-and-drain cycle of the well (in minutes)
How to Find Active Wet Well Volume?
Below examples will help you step by step to calculate the volume of active wet well using the pumping rate and cycle time.
Example 1:
What is the total volume capacity of the Active Wet Well if the pump rate is 500 gallons per minute and the cycle time is 30 minutes?
Solution :
Volume = Pump Rate × Cycle Time
Volume = 500 × 30
Volume = 15,000 gallons
Total volume capacity of the Active Wet Well is 15000 gallons.
Example 2:
What is the total volume capacity of the Active Wet Well if the pump rate is 380 gallons per minute and the cycle time is 21 minutes?
Solution :
Volume = Pump Rate × Cycle Time
Volume = 380 × 21
Volume = 7,980 gallons
Total volume capacity of the Active Wet Well is 7980 gallons.
How Does The ‘Active’ Part of An Active Wet Well work?
The active part in active wet well refers to mechanical mixers or aerators which are inside the well that constantly rotates to aerate the wastewater. Aeration helps to keep the contents in the well oxygenated which helps in easy breakdown of contaminants.
Why Is It Called a Wet Well?
The term ‘wet’ refers that the tank or the well is filled with water/ wastewater. Same as the term dry refers to the well that is completely empty.
What Are The Advantages of Using an Active Wet Well in Wastewater Treatment?
The active wet well helps with equalization, initial treatment and preparation of the wastewater before it moves on to the next steps of the treatment process. This preparatory work improves the overall efficiency of the entire wastewater treatment system.
