Calcium - Wikipedia
Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth''s crust

RO reject water disposal is also commonly used to purify drinking water and desalinate seawater to yield potable water. The water and other molecules with lower molecular weight (specific weight of molecules allowed to pass through is dependent on the selected merane) pass through the micropores in the merane, yielding a purified water stream called the permeate.
