This work intends a methodology for the evaluation of chlorogenic products destinated to the disinfection of drinking waters . The use of organic matter as challenge sustances to emulate the consumption of chlorine showed by untreated waters is postulated. The behavior of suspensions of beer of yeast, peptone and yeast extract against usual dose (10mg / L, expressed as total chlorine) of Tablets of the disodic salt of the Dichloro - S - Triazine - Trione, was evaluated. River water was used as comparison. The concentration of each organic substance that left at least 0,1 mg/L of free chlorine in the test solution, after 30 min was assayed. Then the chlorogenic compound was microbiologically assayed in presence of the organic solutions, according to AFNOR methodology.
Se propone una metodología para la evaluación de productos clorógenos destinados a la desinfección de aguas para consumo, utilizando materia orgánica para simular el consumo de cloro que tienen las aguas no tratadas. Se evaluó el comportamiento de suspensión de levadura de cerveza, peptona y extracto de levadura frente a dosis usuales (10 mg/L, como cloro total) de comprimidos de la sal disódica de la dicloro-S-triazina-triona. Como comparación se utilizó agua de río. Se determinó la concentración de cada sustancia orgánica que despues de 30 minutos dejó 0,1 mg/L de cloro libre en la solución de ensayo. Posteriormente se ensayó microbiologicamente la efectividad del clorógeno en presencia de dichas sustancias según metodología AFNOR.
