What's in your Water? PHYSICAL WATER QUALITY AND FILTRATION

摘要

Filtration can be a significant investment, especially when irrigating from a pond or using recirculated water. If filtration is working correctly, irrigation emitters should not be clogged from suspended particles, and total suspended solids should decrease after filtration. Filters should also remove peat and other particles that create a "demand" on sanitizing agents such as chlorine, copper and ozone. Total Suspended Solids (TSS) is the concentration (in milligrams/ liter or mg/L) of all particulate matter contained in a water sample, and includes fine particles of peat, silt, clay, microbes and other materials. To measure TSS, a water sample is filtered through a very fine screen, which is then dried and weighed.Suspended solids indicate the clogging potential in micro-irrigation lines.
