Reverse Osmosis
Reverse Osmosis (R/O)
Applying pressure beyond osmotic pressure across a semipermeable membrane passes only water molecules, separating ions, organics and microbes — filtering down to 0.0001 microns.

Ion Exchange
Ion Exchange / Softening
Ion-exchange resins remove hardness (Ca²⁺·Mg²⁺) for softening, or selectively remove specific ions such as fluoride, arsenic and nitrate with dedicated resins.

Pre-treatment
Sand filtration, activated carbon and fine filtration remove turbidity, residual chlorine and organics — protecting downstream membranes/resins and boosting efficiency.
