MEMBRACLEAN PCA is a water-based detergent specifically formulated to clean Reverse Osmosis membranes. MEMBRACLEAN PCA will remove hardness (calcium and magnesium) scales and other metal scales. MEMBRACLEAN PCA is also effective against inorganic dirt and salt efflorescence. If used regularly, MEMBRACLEAN PCA maintains system performance and product water quality at a higher level. MEMBRACLEAN PCA reduces operating costs by reducing energy requirements to achieve required product flow. MEMBRACLEAN PCA reduces maintenance costs by prolonging membrane life and reducing strain on other components in the system. Not to be used on acid-sensitive materials.
