Iron and Manganese Bacteria

Iron and manganese bacteria in water can form a filamentous growth which can lead to emitter clogging. The source of the iron bacteria is often a well which has been contaminated during the well drilling process. In addition to the slimy, filamentous deposits produced by the iron bacteria, there is often a swampy or rotten organic matter smell associated with the presence of iron bacteria.
Treatment for iron or manganese bacteria often entails:
Treating the well and/or
Treating the microirrigation system.
