Since lab grade alum was utilized in this experiment and a clog was still present, the presence of foreign material, calcium, or carbonates might not be the main cause of the clogs present in the Honduran plants. An inline strainer might be beneficial to include in future dosing systems but it would be more effective to verify the Honduran operators are cleaning the system regularly and ensuring no foreign matter is making it into the dosing system. Yet it should be noted that this would not eliminate the occurrence of clogs since they may also appear to be caused by the precipitation of aluminum and calcium species in the water.
