Optima Water Solutions designs and supplies Nano Filtration Plants in Delhi 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 Delhi — Why It Matters
Delhi's industrial base — spanning Okhla Industrial Area, Wazirpur Industrial Area, Lawrence Road Industrial Area — continues to expand, and with it the need for dependable NF Plant capacity that meets local discharge norms. Delhi Pollution Control Committee (DPCC) enforces strict wastewater norms under Environment Protection Act. STPs mandatory for group housing societies above 20,000 sqm and all commercial establishments above prescribed threshold.
We work directly with facility owners, developers, and industrial operators in Delhi to deliver NF Plant systems that are correctly sized, properly permitted, and easy to maintain long-term.

Common Questions
Nano Filtration Plant in Delhi — FAQ
What is the cost of a Nano Filtration Plant in Delhi?
NF plant cost in Delhi starts from ₹2–4 Lakh for 500 LPH systems and ranges to ₹15–30 Lakh for 10 m³/hr capacity. Large industrial NF systems for textile colour removal or municipal softening can cost ₹50 Lakh to ₹1 Crore+. Call Optima at +91 9711880791 for a detailed quote.
What is the difference between NF and RO?
RO removes almost all dissolved salts (95–99% TDS rejection). NF selectively rejects divalent ions and larger molecules while allowing monovalent salts to pass — operating at 30–50% lower pressure than RO. Use NF when you need colour removal, hardness reduction, or partial demineralisation without full TDS reduction.
Is NF good for textile effluent treatment in Delhi?
Yes. NF is very effective for colour and COD removal from textile dyeing effluent in Delhi. NF permeate is typically colour-free and can be recycled to dyeing processes, saving fresh water. The concentrate (reject) goes to the ETP for further treatment. NF + ZLD is a common combination for textile ZLD systems.
Can NF replace water softener for hardness removal?
Yes. NF effectively removes hardness (calcium, magnesium) and sulphates without using salt-based ion exchange. Unlike conventional softeners that require regeneration with salt (adding sodium to effluent), NF physically separates hardness ions without chemical addition. Preferred choice where salt discharge is restricted.
How long do NF membranes last?
NF membranes typically last 3–7 years with proper maintenance. Regular backwash, CIP cleaning, and antiscalant dosing are essential. Optima provides AMC services in Delhi including scheduled CIP, performance monitoring, and membrane replacement when required.
