Rediseño del filtro de 5µm de una planta de producción de agua purificada // Redisign of 5µm filter in production plant of purified water
Abstract
El agua purificada es una materia prima esencial en los procesos productivos en la industria farmacéutica y biofarmacéutica. El incremento de la disponibilidad y calidad de la misma se puede mejorar con nuevos elementos de diseño como elemento dentro de la confiabilidad operacional. El objetivo de este trabajo fue realizar una adecuación en el proceso de obtención de agua purificada transformando el diseño del filtro de 5 µm de la primera etapa del proceso, concebido en su diseño original como desechable por uno de acero inoxidable y la adición de una acción de retro lavado, para reducir los costos de operación por concepto de remplazo. Entre los métodos empleados se encuentra el modelo de confiabilidad operacional que incluye el diseño en la confiabilidad de proceso, el empleo de la metodología de Harrington adecuada al método de Nigel Cross para la evaluación de los cambios realizados, lo que dieron como resultado la factibilidad de la sustitución del filtro SupaGard del fabricante Sartorius por el filtro SupaMesh del fabricante Amazon Filter, mejorando la producción de agua purificada en 3300 lts semanales.
Palabras claves: planta de agua; filtros; agua purificada; confiabilidad operacional; rediseño.
Abstract
Purified water is an essential raw material in production processes in the pharmaceutical and biopharmaceutical industry. The increase in its availability and quality can be improved with new design elements as an element within operational reliability. The objective of this work was to carry out an adaptation in the process of obtaining purified water, transforming the design of the 5 µm filter of the first stage of the process, conceived in its original design as disposable by one of stainless steel, and the addition of an action backwash, to reduce operating costs for replacement. Among the methods used is the operational reliability model that includes the process reliability design, the use of the Harrington methodology appropriate to the Nigel Cross method for the evaluation of the changes made, which resulted in the feasibility of the replacement of the SupaGard filter from the manufacturer Sartorius with the SupaMesh filter from the manufacturer Amazon Filter, improving the production of purified water by 3300 liters per week.
Key words: water plant; filter; puified wáter; operational realiability; redisign.
