Minerals (hardness) is not removed by ultrafiltration, this includes:
• Total Hardness, hard water is mainly calcium and magnesium and is not considered a health
risk but can be unpleasant to taste and cause a build up of scale in pipes (WHO safe drinking
standard-Max 500 mg/L)
• Calcium, Carbonate (WHO safe drinking standard- Max 250 mg/L)
• Iron and Manganese (unless first oxidised) (WHO safe drinking standard- 0.4 mg/L;
Note: exceeding this level is not unsafe but is unpleasant to taste - max 1.0 mg/L)
• Magnesium (WHO safe drinking standard- Max 150 mg/L)
3.
Salinity and salts are not removed by ultrafiltration include:
• Salinity (WHO safe drinking standard - Max 250 mg/L)
• Chloride and Sodium (WHO safe drinking standard - Max 600 mg/L)
• Conductivity (WHO safe drinking standard - Max 2000 uS/cm)
4.
Total dissolved solids (TDS) cannot be successfully removed by ultrafiltration:
• TDS (WHO safe drinking standard - Max 1000 mg/L)
• TDS contain a wide range of substances including organic and inorganic (chemicals)

Ultrafiltration will have NO effect on ph levels:
• pH Scale (WHO safe drinking standard 6.5 – 9.0)
