Factibilidad de aplicación de una arcilla cubana para el enriquecimiento en minerales de agua potable | Feasbility of application of Cuban clay for the drinking water mineral enrichment

Como parte del proyecto de implementación de la dieta macrobiótica en Cuba se valoró la situación de una arcilla italiana, empleada para enriquecer al agua potable con sales minerales, por una cubana similar (bentonita natural de Managua tipo 1). La caracterización minerológica, química y granulométrica de ambas arcillas fue similar. Se estudió el efecto de tres concentraciones de arcilla cubana en agua potable (0,1; 0,5 y 1 %) después de 24 h. Este tratamiento incrementó significativamente las concentraciones de sodio, magnesio y hierro y disminuyó las de calcio, cinc y cobre en el agua; todos los elementos cumplieron con las normas vigentes de agua potable.

The substitution of an Italian clay, used to enrich the supply water with mineral salts, by a similar one from Cuban origin (natural bentonite of Managua type 1) was considered, as part of a project for the implementation of the macrobiotic diet in Cuba. The mineralogical, chemical and granulometric characteristics of both clays were similar. The effect of three concentrations of Cuban clay in drinking water (0.1; 0.5 and 1%) on physical-chemical characteristics of the water after 24 h of interchange was studied. The water treated achieved the physical-chemical characteristics established in the Cuban standards for consumption water. The effect of 1% of this clay on concentration of 16 elements that could be present in the water after 24 h was studied. This treatment increased the concentrations of sodium, magnesium and iron significantly and diminished those of calcium, zinc and copper in the water all the elements achieved the established standars.
