Solutions to Existing Clogging Problems

I already know what is causing the clogging

The treatment to solve a clogging issue in drip systems generally depends on the cause of the clogging.

Particulate clogging problems result when there are particles (sand, silt or clay mineral material or other contaminants) suspended in the water. Emitter clogging from particulates can occur with surface water sources (rivers, reservoirs, ponds, etc.) and with groundwater. Click here for more information on particulate clogging problems and ways to solve them.

Biological clogging problems are caused by biological materials (algae, bacterial slimes, etc.) that either are suspended in the water or are growing inside the microirrigation system. Most biological clogging problems are associated with surface water sources. Click here for more information on biological clogging and ways to mitigate it.

Chemical precipitate clogging problems are nearly always associated with groundwater sources. The chemical precipitates are in solution in the groundwater, but when the pumped water comes in contact with air, chemical precipitates can form and settle out in the microirrigation system. Common chemical precipitates include calcium carbonate (lime) and iron. Click here for more information on chemical precipitate clogging and ways of dealing with it.
