Introducing the Pro-Acid Series: Our state-of-the-art acid-resistant special separation coil membrane element, designed to revolutionize industrial acid solution purification.Crafted with precision using PSI MEMBRANE®'s proprietary TFN acid-resistant membrane and unique acid-resistant materials, this powerhouse membrane boasts exceptional anti-pollution capabilities, high flux performance, and robust high-pressure tolerance. It can achieve remarkable metal concentration levels in sulfuric acid up to 20% and phosphoric acid up to 30%, making it ideal for acid purification applications. Perfect for removing large molecular impurities from acid solutions, the Pro-Acid Series promises an impressive lifespan of over 12 months, maintaining stable, high-flux operation even in rigorous strong acid environments.
