IRASD-200 Antiscalant And Dispersant


IRASD-200 is used for RO, NF(nanofiltration), and UF(ultrafiltration) systems. It can effectively inhibit scaling on the membrane surface. And also improve water quality and lower operating costs. IRASD-200 has the following properties.

  1. The original liquid is 11 times concentrated. As a result, 90% of transportation costs and storage space are saved.
  2. Prevent pollution from inorganic salt, metal scale, and some organic substances.
  3. Not flocculate with ferric oxide, aluminum oxide, or silica oxide to form a suspended substance.
  4. Effectively control the pollution of ferric, aluminum, and heavy metal.
  5. No content of phosphate of phosphorous.
  6. Used in RO CA(cellulose acetate), TFC, NF(nanofiltration), and UF(ultrafiltration) membranes.
  7. Good solubility and stability.
  8. Stable in extreme pH and temperature.
  9. Due to IRASD-200 special molecular structure. It is safe for the membrane. Even high medicine input (equipment trouble, for example) will not lead to its deposit, crystallization, or adsorption on the membrane surface and lead to membrane blockage.
