Remineralisation of Reverse Osmosis (RO) Water Using Synthetic Aragonite
ABSTRACT Reverse osmosis (RO) treated water often requires remineralisation to restore Ca2+ ions, hardness and alkalinity, particularly for potable water. This study compares the dissolution characteristics of two forms of calcium carbonate, aragonite and calcite.

This review examines the physicochemical properties of geopolymers, focusing on the effects of calcium content, heavy metal impurities and acid activation. It distinguishes geopolymers from other alkali‐activated materials based on structure and synthesis precursors. Their use as water treatment adsorbents is compared with ceramic filters, highlighting
