Location: Water Management and Conservation Research
Project Number: 2020-13000-005-011-S
Project Type: Non-Assistance Cooperative Agreement
Start Date: Sep 15, 2022
End Date: Sep 14, 2026
Objective:
Evaluate the potential to use nanobubbles to treat wash water from cut lettuce packaging facilities.
Approach:
We will evaluate the impact of nano bubbles (NB) gas type (ozone vs air), pH, carbonate, calcium and temperature on washing lettuce with NBs and the subsequent filterability of the washed water. We will employ a membrane-based NB generator. The system has a special ozone resistant membrane that allows generating ozone nanobubbles in addition to oxygen, air, carbon dioxide, and nitrogen.
