Abstract
La presente propuesta es convertir un efluente en un recurso económico, para tal propósito se realizó pruebas experimentales a nivel laboratorio, donde se ensayó la neutralización en la refinación del aceite de pescado, el hidróxido de potasio como agente neutralizante que se propone sustituir al hidróxido de sodio, que actualmente la industria aceitera utiliza, para neutralizar la acidez libre del aceite crudo de pescado. Al realizarse la neutralización con hidróxido de potasio para reducir la acidez libre de los aceites, y realizar los lavados del aceite y neutralizar la acidez de estas aguas con hidróxido de amonio, se obtiene una solución mezcla con propiedades fertilizantes. Para mostrar las propiedades fertilizantes de esta mezcla obtenida se utilizaron como fertilizante foliar aplicado al cultivo rabanito, para ello se realizó la experimentación en campo, se hizo la instalación utilizando el Diseño de Bloques Completamente Aleatorio, con cinco tratamientos.
The present proposal is to convert an effluent into an economic resource, for this purpose experimental tests were carried out at the laboratory level, where neutralization was tested in the refining of fish oil, potassium hydroxide as a neutralizing agent that is proposed to replace potassium hydroxide sodium, currently used by the oil industry to neutralize the free acidity of crude fish oil. When neutralizing with potassium hydroxide to reduce the free acidity of the oils, and washing the oil and neutralizing the acidity of these waters with ammonium hydroxide, a mixed solution with fertilizing properties is obtained. To show the fertilizing properties of this obtained mixture, they were used as a foliar fertilizer applied to the radish crop, for which field experimentation was carried out, the installation was made using the Completely Random Block Design, with five treatments.
