Development of a Low Pressure and Low Flow Water and Energy Efficient Media Filtration System
Lead Researcher: Kaomine Vang

The need: Common media filters require anywhere from 30-50 psi to operate properly. With the advent of new irrigation technology and drip tape designs, such high-pressure ratings are non-optimal and can be destructive to a drip system. Currently, most drip tape operates in the range of 8 to 15 psi, which means that the excess pressure is energy wasted. New designs in media filtration that perform the same functions of the technology currently in use while operating at lower pressures can lead to significant energy cost savings.  

 The goal: This project is focused on prototyping and testing a new energy efficient media filter that will require less water for back flushing and make improvements in part from insights gained through repeated performance comparison with other commercial filters.  

 The impact: Developing new innovative technology is challenging. During this project, media compaction and different media types affected testing outcomes in some surprising ways. We discovered that the canister holding the media needed modification for less head loss and were able to make necessary adjustments so that the unit would work as planned. Even so, the pressure loss of the unit was higher than anticipated. Product testing was completed in June 2020 and results were shared with collaborators.
