Optima Water Solutions is an NF Plant Supplier in Chennai. We design and supply Nano Filtration Plants for selective removal of divalent ions, colour, hardness, and specific organic compounds, while allowing monovalent salts to pass — delivering partially softened, colour-free water for textile, food, pharmaceutical, and municipal applications. ISO 9001:2015 certified with 12+ years of experience.
What is a Nano Filtration Plant?
Nanofiltration (NF) is a membrane filtration process with pore sizes between Ultrafiltration (UF) and Reverse Osmosis (RO) — typically 0.001–0.01 microns. NF membranes selectively reject divalent and multivalent ions (calcium, magnesium, sulphates, heavy metals) while allowing monovalent ions (sodium, chloride) to pass at lower operating pressure than RO.
This selective rejection makes NF ideal for water softening, colour removal from textile effluent, natural organic matter (NOM) removal, and pharmaceutical process water where partial demineralisation is required without full RO treatment.
NF systems consume 30–50% less energy than equivalent RO systems due to lower operating pressures.
Nano Filtration Plant in Chennai — Why It Matters
Chennai's NF demand includes water softening for residential clients and colour/hardness removal for select industrial applications, offering a lower-cost path than RO where complete demineralization isn't the goal.
Coastal groundwater conditions in some Chennai areas make NF a useful intermediate treatment option between standard filtration and full RO.
Key industrial areas we serve in Chennai:
Regulatory Note: Tamil Nadu Pollution Control Board (TNPCB) requires TNPCB-approved ETP/STP for all industries and large buildings in Chennai.

Common Questions
Nano Filtration Plant in Chennai — FAQ
When is NF preferable to RO for Chennai clients?
When softening or selective ion removal is the goal rather than complete demineralization — NF achieves this at lower operating cost, particularly useful given Chennai's variable water sources.
What does an NF plant cost in Chennai?
Cost typically runs ₹2 Lakh to ₹30 Lakh depending on capacity. Call +91 9711880791 for a site-specific quote.
Does coastal Chennai groundwater suit NF treatment?
For moderate salinity conditions, NF can be a useful intermediate option, though areas with high salinity typically need full RO or brackish water treatment instead.
What NF capacity suits a Chennai residential development?
This depends on total water demand, typically 1,000 LPH to 300 KLD for most Chennai residential projects.
