After the successful run of this trial it can be concluded that carbonates present in the alkaline tap water were indeed the problem causing the lower efficiency of the lime feeder system and since this difficulty will not be faced in the Honduran source water (having very low pH)the lime feeders can be made to run successfully for 12 hours after making minor further adjustments in the dosage of lime and water flow rate. This experiment also showed that the flow rate that was being used so far (120 mL/min) to get very high upflow velocities (4.42 mm/s) was not necessary and was causing higher loss of lime. In order to get an average lime feeder run of 12 hours, the lime dose will have to be further increased. Details regarding the these next steps can be viewed on the Future Challenges page.
