Key Properties
Purolite A500MBOH is designed for use as the anion component in mixed bed demineralisation units, offering excellent separation from cation components. It is particularly suited for difficult operating conditions, including resistance to osmotic stress and high flow rates. Its macroporous structure provides superior resistance to fouling from organic materials like fulvic and humic acids compared to gel resins and many other macroporous resins. The resin also exhibits excellent resistance to osmotic and thermal shock. It has a high affinity for strong mineral acid anions, organics, and silica, which is beneficial for producing high-quality treated water but requires efficient regeneration.
