ReCalu2122 | Remineralization & pH Stabilization System
The final step that turns desalinated water into drinking water.
ReCalu2122 is INFRACORPu2019s advanced post-treatment platform engineered to restore natural minerals, stabilize pH, and ensure safe, corrosion-controlled drinking water quality after desalination.
Using optimized limestone filtration or precision lime dosing, ReCalu2122 rebuilds essential mineral content, enhances taste, and protects distribution networks.
ReCalu2122 unlocks:
- Natural remineralization
- Accurate pH adjustment
- Alkalinity restoration
- Corrosion control
- Final potability compliance
In simple terms:
ReCalu2122 gives clean desal water its u201cminerality back,u201d making it balanced, healthy, and life-ready.
ReCalu2122 Remineralization Description
The seawater product water has low pH or acidic, contains low buffering capacity, and has low alkalinity andu00a0 hardness (concentration of calcium and magnesium is very low). This low pH and low alkalinity and hardnessu00a0 water may have undesirable consequences to the distribution system plumbing /pipe materials, downstream wastewater systems, and may not be favorable for drinking or irrigation purposes.
Post-treatment systems are designedu00a0 to adjust the final productu2019s minerals composition to accommodate water quality requirements.
For drinking water purposes, it is required to meet and adjust the physical & chemical parameters such as pH, TDS, Turbidity, Hardness,u00a0 Alkalinity and others in the final treatment process selected for post-treatment.
A commonly used operation in the remineralization process is to contactu00a0CO2u00a0acidified desalinated water with a bed of domestic limestone. Limestone dissolution provides two essential ingredients to the water u2013 bicarbonate alkalinity and calcium content:
CaCO3u00a0+ CO2u00a0+ H2O = Ca+2u00a0+ 2HCO3
Overall Purpose
- Stabilization u2013 Prevents corrosion of pipes by raising alkalinity and hardness
- pH Adjustment u2013 Brings RO permeate to a neutral or slightly alkaline range (pH 7u20138).
- Re-mineralization u2013 Adds calcium and bicarbonate for taste and health (important in drinking water applications).
- Langelier Saturation Index (LSI) Correction u2013 Ensures water is slightly scale-forming rather than aggressive/corrosive.
Post-treatment processes typically includeu00a0stabilization, disinfection and corrosion control, and can include degasification and/or air stripping processes. Four primary issues concerning the post-treatment water are blending, remineralization, disinfection and the materials used for storage.
