Filtration to remove suspended particles can be a significant investment for greenhouse and nursery businesses, especially when irrigating with recirculated or surface water sources.
Filtration to remove particles from irrigation water is a key first step underlying other aspects of water treatment, to remove pathogen spores, material that can clog irrigation lines, and reduce demand for sanitizing chemicals.
Objectives of this research included characterizing the particle size distribution and amount of suspended solids in irrigation water sources from a survey of plant nurseries, before and after filtration.
