Description

• Material of construction: WFI tanks are typically made of high-quality stainless steel (316L or 316Ti) to ensure that the water is not contaminated by the tank material. The stainless steel used in the construction of WFI tanks is of pharmaceutical grade and is polished to a smooth surface finish to prevent the buildup of bacteria and other contaminants.
• Design and construction standards: WFI tanks are designed and constructed according to industry standards and regulations, such as the US FDA (Food and Drug Administration) and European Pharmacopoeia. The tanks are designed with features that prevent contamination, such as sloping bottoms, smooth interior surfaces, and dedicated WFI distribution systems.
• Validation and qualification: WFI tanks are subject to rigorous validation and qualification procedures to ensure that they meet the required standards and specifications. This involves testing the tanks for cleanliness, integrity, and resistance to corrosion and other forms of degradation.
  Size and capacity: WFI tanks come in various sizes and capacities, depending on the needs of the facility. The size and capacity of the tank should be chosen based on the anticipated demand for WFI and the available space in the facility.
• Quality control monitoring: WFI tanks are equipped with monitoring systems that measure the temperature, pH, conductivity, and microbial count of the water stored in the tank. The monitoring systems are connected to alarms and automatic shut-off systems to alert personnel if there are any deviations from the required specifications.
• Cleaning and maintenance: WFI tanks are designed for easy cleaning and maintenance to ensure that the water stored in the tank remains of high quality. The tanks are typically fitted with CIP (Clean-In-Place) systems and other features that facilitate cleaning and sanitization.
