Ultra-pure water plays a critical role in preventing scaling and mineral buildup in autoclave machines used in the Central Sterile Supply Department (CSSD) of hospitals. Hard water contains calcium and magnesium salts that can deposit inside the autoclave boiler, leading to reduced heating efficiency, frequent maintenance, and even equipment failure. Scaling not only shortens the lifespan of the autoclave but also increases energy consumption and operating costs. Using ultra-pure or softened water helps maintain consistent steam quality, ensuring effective sterilization of surgical instruments. Studies have shown that proper water treatment can extend autoclave life by up to 50% and reduce maintenance frequency by over 30%. Therefore, incorporating a water purification system is essential for CSSD efficiency, patient safety, and hospital cost savings.
