Reverse Osmosis (RO)

Definition: Reverse osmosis is a water purification process used to remove impurities from water. It involves forcing water through a semi-permeable membrane, which allows water molecules to pass through while blocking larger molecules, contaminants, and minerals.

Function in the Aquarium: The result is purified water on one side of the membrane, leaving behind substances like salts, minerals, and impurities. RO is effective in producing clean water for aquariums by significantly reducing the total dissolved solids (TDS) in the water.
