In the world of environmental and water treatment, anaerobic digestion plays a crucial role in breaking down organic waste and producing valuable biogas. For this process to run efficiently, a robust circulation and mixing system is vital. One innovative technology that stands out in this area is the GasLifter, developed by Walker Process Equipment.
What is a GasLifter?
The GasLifter is a specialized system that utilizes the biogas produced within the digester itself to drive circulation and mixing. It works by strategically placing a series of vertical pipes, known as risers, within the digester. These risers are connected to a header pipe that runs along the top of the digester. As biogas is generated, it rises through the risers and enters the header pipe, creating a pressure difference that draws digester liquid upwards.

Scenario: You are a consultant working with a wastewater treatment plant that is considering implementing a GasLifter system to improve their anaerobic digester performance. The plant manager expresses concern about the initial investment cost and wants to know how long it will take for the energy savings to recoup the cost.
Task:
The correction for this exercise will depend on the specific information you gather during your research. However, the general steps involved are:
For example, if the GasLifter system costs $100,000 and the annual energy savings are $20,000, the payback period would be 5 years ($100,000 / $20,000 = 5 years).
