IR-0100 RO Antiscalant and Dispersant


IR-0100 is a high-effective scale inhibitor. It is suitable for reverse osmose (RO), nanofiltration (NF) and ultrafiltration (UF) system. IR-0100 RO antiscalant and dispersant can inhibit the scale deposit on the membrane surface, improve water quality, lower operation expanse.

This product has the following properties.

  1. Inhibit inorganic scale formation for a wide concentration span, the largest permitted LSI value is 2.8 when no acid is added.
  2. Not flocculate with ferric oxide, aluminum oxide or silica oxide to form suspended substance;
  3.  Inhibit the pollution from ferric, aluminum or heavy metals pollutants. The permitted ferric concentration for inlet water supply can reach to 8.0ppm.
  4. Inhibit the flocculate and deposit of silica, the permitted silica concentration for condense side can reach to 290 ppm.
  5. Be used in CA, TFC, NF and UF membranes for RO system.
  6. Good solubility and stability.
  7.  Effective in pH 5-10.

The dosage is determined by water quality analysis and condition of reverse osmose system. In the recommended range of dosage, most scales can be under control. Such as calcium carbonate, calcium sulfate, barium sulfate, ferric hydroxide, aluminum hydroxide, and silica.

The following formula can be used to calculate the IR-0100 volumes required to add to the medicine box.

ir 0100
U—— condense liquid volumes required, Litre, (L)

Q—— reverse osmose water supply flow, tons/hour (T/h)

a—— dosage required, gram/ton, (ppm, g/T) (standard liquid)

V—— the effective volume of medicine box, liter (L)

ρ—— density of the IR-0100, kg/L, the density is 1.45

x—— the actual flow of medicine operation pump, liter/hour (L/h)

1000 —— conversion coefficient

8 —— condense index

Notes: the value a (dosage required) can refer to the special software of QingLi Company.

Package and Storage:

The original package is 8 times condense liquid, 5 gallons (27.55kg) per barrel. After diluting 8 times, 220.4kg per barrel.
