IR-0100 RO Antiscalant and Dispersant


IR-0100 is a high-effective scale inhibitor. It is suitable for the reverse to osmose (RO), nanofiltration (NF), and ultrafiltration (UF) systems. It can inhibit the scale deposit on the membrane surface, improve water quality, and lower operation expanse. In addition, 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 oxide ferric, aluminum, or silica to form a suspended substance.
  3. Inhibit the pollution from ferric, aluminum, or heavy metals pollutants. For example, the permitted ferric concentration for the inlet water supply can reach 8.0 ppm.
  4. Inhibit the flocculation and deposit of silica; the permitted silica concentration for condense side can reach 290 ppm.
  5. Be used in CA, TFC, NF, and UF membranes for RO systems.
  6. Good solubility and stability.
  7. Effective in pH 5~10.

The dosage is determined by water quality analysis and the condition of the reverse osmose system. In the recommended dosage range, 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 Usage

where: 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.

Packing and Storage:

The original package is eight times condensed liquid, five gallons (27.55kg) per barrel. After diluting eight times, 220.4kg per barrel.
