What is reverse osmosis?
Reverse osmosis is a filtration process that works by using pressure to force
a solution through a membrane. Thus retaining the solute on one side and
allowing the pure solvent to pass to the other side. This is the reverse of
the normal osmosis process, which is the natural movement of solvent
from an area of low density or concentration, through a membrane, to an
area of high density or concentration when no external pressure is applied.

The standard reverse osmosis process goes through five stages, namely:
Stage 1 (PP sediment filter) - To remove sand, silt, dirt and rust particles
Stage 2 (Granular activated carbon filter) - To absorb chlorine, organic
matter, odour, smell turbidity.
Stage 3 (Block activated carbon filter) - To absorb chlorine, organic matter,
odour, smell turbidity and suspended particles.
Stage 4 (RO membrane) - This semi-permeable membrane with 0.0001
micron filtration, separates and removes bacteria, heavy metal, salt,
bad mineral substances and other dissolved matter in the running water.
Stage 5 (Post inline carbon filter) - This final filter is used to absorb the
remaining odour and adjust the taste.
