Product Description
R.O. Antiscalant is a specialized chemical used to prevent scale deposits in reverse osmosis (R.O.) membranes. It is a clear, colorless liquid formulated with polyphosphates and polymeric phosphonate-based compounds that inhibit calcium, magnesium, and other mineral scaling, optimizing membrane performance and extending system lifespan. The product is highly soluble in water with a neutral pH range between 7 and 9. It is widely used in industries such as water treatment, manufacturing, food and beverage, and pharmaceuticals across Kenya, Uganda, Tanzania, Rwanda, and the larger East African region.
