NY413 - Investigation of Sand Filtration for Nursery Recycling Systems

Trials into the world’s oldest water treatment process - sand filtration - have shown it effectively controls Phytophthora and Fusarium in recycled nutrient solutions and contaminated irrigation water in hydroponic systems. This project resulted in recommendations for improved operation and construction of filters for maximum efficacy. It recommended slow sand filtration be used as an effective alternative to other methods of chemical disinfestation and water treatment in the hydroponics industry.
