The remineralising cartridge is an inline 275mm long that is usually installed after the reverse osmosis filter process to raise the pH of the water. It can be installed as a final stage or installed before the last carbon filter to reduce the effects of the cartridge.
The cartridge contains a number of ceramic balls and mineral rocks that essentially add calcium into the water raising the pH to between 8-9.5 depending upon the incoming water. The cartridge also reduces the Oxygen Reduction Potential (ORP) of the water to between -25 to -180mv to assist the bodies metabolic functions.
A remineraliser can be added as 5th or 6th stage to a 4 stage reverse osmosis system and can be installed after a resin cartridge although it is already included as standard os the ASRO4R unit.
