AZGFD Aeration Project

Laid the groundwork for an off-grid aeration system for a fish hatchery in Show Low, AZ

Overview

In the tail end of my freshman year, I joined ASU's Engineering Projects in Community Service (EPICS) - where I took on my first team leadership role. My role in this project involved leading early-stage system design and validation for an off-grid aeration solution to support a fish hatchery. Work included preliminary testing, data analysis, and early component selection to inform a robust, energy-efficient aeration system architecture. The team and I traveled out to Show Low, Arizona where the hatchery was located to find out more information about the site. I helped create prototype circuits implementing solar power to power an aeration system for the hatchery.

Process

  1. Interviewed client to know desired dissolved oxygen output
  2. Benchmarked with existing aeration systems
  3. Researched methods to make offgrid power
  4. Selected preliminary diffuser types and compressor options
  5. Conducted hand calculations for estimated power requirements
  6. Developed prototype proof-of-concept aeration circuit
  7. Outlined a roadmap for scaling for on-site installation

Outcomes and Results

With the use of generous EPICS funding and university-provided materials, the team and I were able to conduct many tests on small-scale aeration systems that were solar-powered. To obtain a proof-of-concept was a big milestone, however implementing the system at a wide scale was a different beast as the conditions were much different. We were able to present our findings to a panel of industry engineers to review our designs and gain valuable feedback to set us up for success. Unfortunately, I left the team before I could see how the concept was implemented at the hatchery as I gained a bigger role in the solar car team, but the direction the project was going was very promising.

Reflection

This project will always have a special place in my heart for its role in getting me really interested in working in a project team. When I started on this project, I was a young freshman/sophomore still freshly finding out what exactly I wanted to do in engineering, and this project was greatly helpful in realizing my passions. Without being on this project, I would not have developed such a strong desire for a career path emphasizing a more sustainable - in any way, shape, or form. I also appreciated the project for diversifying my skills as an engineer by introducing me to many concepts on power and circuitry that I would not have received in my undergrad.
