Computation based on Hallopeau-Dubin model, which also takes into account an estimate of ionic strength and uses the pH, TAC couple, as well as simplified equations

Results

Langelier Saturation Index (LSI)

LSI value: No value

Type of Water:
  • According to Langelier 1936: No information
  • According to Carrier 1965: No information
It measures whether the water is under-saturated (corrosive) or over-saturated (scaling) with respect to calcium carbonate. It usefull for preventing damage to water distribution systems and equipment.
Ryznar Index (RI)

RI value: No value

Type of Water:
  • According to Ryznar 1942: No information
  • According to Carrier 1965: No information
It considers factors such as pH, alkalinity, and temperature. This index is valuable for assessing the potential for corrosion and helps in selecting appropriate water treatment methods.
Larson Ratio (LR)

LR value: No value

Type of Water:
  • According to Larson 1958: No information
It calculates the ratio of sulfate ions to chloride ions in water. It is particularly important in construction and civil engineering to avoid corrosion-related issues in infrastructure.
