El objetivo de este trabajo es el estudio isotérmico a 60 oC de la precipitación de CaCO3 en un destilador solar experimental, utilizando como afluente agua subterránea con alto contenido de calcio, bicarbonatos y sulfatos solubles. Se efectuaron tres experimentos de la reacción entre el calcio con los iones bicarbonato. El primer experimento se siguió durante 5 horas con el destilador libre de incrustaciones; el segundo durante 9 horas con incrustaciones y el tercero por un periodo de 8 horas con un tiempo previo de 72 horas de contacto entre el precipitado y la solución. Durante las dos primeras horas en los tres experimentos se precipitaron 71.7, 253.0 y 400.7 mg de CaCO3 respectivamente. En el precipitado se encontró calcita como única fase cristalina.]]></p></abstract>

The objective of this work was the study of isothermic precipita tion of CaCO3 in a experimental solar still using groundwater as water supply with high concentrations of soluble calcium and sulfates. Three experiments of calcium and bicarbonates reaction were performed. The first experiment was followed during 5 hours with incrustations free still, the second, during 9 hours with incrustations and the third experiment in a 8 hours period with 72 hours of previous contact between the solution and the precipitate. During the first two hours in the three experiments, 71.70, 273.00 and 400.70 mg of CaCO3 were formed respectively. In the precipitate was found calcite as only crystalline phase.]]></p></abstract>
