The table below shows actual measures of pH and alkalinity in AguaClara treatment plants in Honduras. To have high accuracy in the lime feeder design, the conditions of raw water in the laboratory will be simulated. The results in the table demonstrate a decrease of pH during the treatment process which is strongly visible on Cuatro Comunidades and Tamara plants. 
OJOJONA | RAW WATER | TREATED WATER |
|---|---|---|
pH (UN) | 6.51 - 6.8 | 6.26 - 6.56 |
Alkalinity (mg/L CaCO3) | 34.7 - 36.3 | 17.3 - 19.4 |
MARCALA | RAW WATER | TREATED WATER |
pH (UN) | 6.44 - 7.28 | 6.07 - 6.45 |
