Optima Water Solutions designs and supplies Nano Filtration Plants in Raipur 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 Raipur — Why It Matters
Facilities operating near Urla Industrial Area, Siltara Growth Centre, Birgaon Industrial in Raipur face close scrutiny over wastewater discharge. CECB enforces strict effluent norms for steel and iron industries in Raipur, India's steel capital. ETPs mandatory for all industrial units. STPs required for large residential complexes under RERA.
Optima Water Solutions has built a track record of NF Plant installations serving Raipur and the surrounding area, with local support for commissioning, operator training, and ongoing maintenance.

Common Questions
Nano Filtration Plant in Raipur — FAQ
What is the cost of a Nano Filtration Plant in Raipur?
NF plant cost in Raipur 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 Raipur?
Yes. NF is very effective for colour and COD removal from textile dyeing effluent in Raipur. 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 Raipur including scheduled CIP, performance monitoring, and membrane replacement when required.
