Optima Water Solutions designs and supplies Nano Filtration Plants in Vapi 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.
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.
GPCB mandates strict ETP/CETP compliance for Vapi's chemical industrial belt, one of the most heavily regulated industrial zones in Gujarat given its dense chemical manufacturing base. This makes properly designed NF Plant systems essential for operators in Vapi, particularly around GIDC Vapi, GIDC Umbergaon.
Optima Water Solutions supports clients in Vapi with end-to-end NF Plant project delivery — from design and manufacturing to installation, commissioning, and long-term AMC support.

NF plant cost in Vapi 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.
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.
Yes. NF is very effective for colour and COD removal from textile dyeing effluent in Vapi. 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.
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.
NF membranes typically last 3–7 years with proper maintenance. Regular backwash, CIP cleaning, and antiscalant dosing are essential. Optima provides AMC services in Vapi including scheduled CIP, performance monitoring, and membrane replacement when required.
