CDI Based
Water Treatment
Next-generation, chemical-free desalination that recovers up to 80% of water while preserving essential natural minerals.
Smarter purification,
cleaner water.
Capacitive Deionization removes dissolved salts by drawing charged ions onto porous electrodes with a low-voltage electric field — no membranes to clog and no chemicals to dose.
The result is a highly efficient purification cycle that delivers balanced, great-tasting mineral water while dramatically cutting waste and running cost.
How CDI works
Engineered to cost less over its life.
Natural mineral restoration
Optimum mineral balance — tunable TDS and concentration of minerals.
Longer module life
4–6 years versus 12–24 months for typical RO membranes.
Lower treatment cost
Just 0.1–0.2 INR per litre against 0.3–1.0 for RO.
Auto cleaning included
Built-in self-cleaning keeps performance steady over time.
Water and wastewater, end to end.
From compact units to large-scale plants, NERITH engineers, builds and commissions complete treatment systems.
Capacitive Deionization
Chemical-free desalination with 80% recovery and tunable mineral output.
