Introduction to Slow Sand Filtration
Recycled irrigation runoff water is a viable alternative for nursery and greenhouse production. However, it is likely to have plant pathogens present including: viruses, water molds, fungi, nematodes, and bacteria. To prevent plant pathogen spread, recycled irrigation water needs to be disinfected. Typical sanitation techniques include using chemicals (e.g. chlorine products or ozone), heat treatments, or ultraviolet light to kill pathogens.
