Abstract
A composition capable of setting to produce a cementitious material for use in remineralizing a fluid is provided. The composition includes a first magnesium-containing compound, a second magnesium-containing compound, and water present in the composition in an amount sufficient such that the composition sets to a cementitious material.
Claims20
An apparatus for re-mineralizing an aqueous solution, the apparatus comprising:
- a mineralization unit having an inlet to receive a permeate stream, a cementitious material disposed within the mineralization unit to mineralize the permeate stream to generate a mineralized stream having a total dissolved solid (TDS) content that is greater than the permeate stream, and an outlet to discharge the mineralized stream,
- the cementitious material including a first magnesium-containing compound, a second magnesium-containing compound, water present in the composition in an amount sufficient such that the composition sets to the cementitious material, the water being present in the composition at a total weight percent of at least 20% (w/w), and
- the cementitious material designed to dissolve in the aqueous solution and being substantially free of a water-resistant modifier,
- wherein a total weight percent of CaCO3 present in the cementitious material is less than 5% (w/w).
A composition capable of setting to produce a cementitious material for use in re-mineralizing an aqueous solution, the composition comprising:
- a first magnesium-containing compound, a second magnesium-containing compound, water present in the composition in an amount sufficient such that the composition sets to the cementitious material, the water being present in the composition at a total weight percent of at least 20% (w/w), and less than 5% (w/w) total weight percent CaCO3,
- the cementitious material being designed to dissolve in the aqueous solution,
- wherein the cementitious material is substantially free of a water-resistant modifier.
A composition capable of setting to produce a cementitious material for use in re-mineralizing an aqueous solution, the composition comprising:
- a first magnesium-containing compound present in the composition at a total weight percent of at least 15% (w/w), a second magnesium-containing compound, water present in the composition in an amount sufficient such that the composition sets to the cementitious material, and less than 5% (w/w) total weight percent CaCO3,
- the cementitious material being substantially free of a water-resistant modifier, and
- the cementitious material designed to dissolve in the aqueous solution upon submersion.
