Membrane Systems
Ultra-pure water. Precisely engineered at the molecular level.
The Challenge
Why can't municipal water meet pharmaceutical, data centre, and food-grade process requirements?
Pharmaceutical manufacturers require USP-grade purified water (PW) and water for injection (WFI). Data centers need ultra-low conductivity cooling water to prevent corrosion. Food processors need water free of pathogens and chemical residues. Standard municipal or groundwater supply — with TDS of 500–3,000 mg/L — cannot meet these demands without advanced membrane treatment.
Conductivity achievable with Navbharat Water's double-pass RO + EDI systems for pharma PW
How It Works
Four membrane technologies. One precision outcome.
Navbharat Water deploys RO, UF, NF, and MF membranes selectively — often in combination — to achieve the exact water quality your process requires. No over-engineering. No under-specification.
Reverse Osmosis
High-pressure (15–80 bar) rejection of dissolved salts, organics, and 99%+ of bacteria. Used for desalination, DM water production, and ZLD brine concentration. Recovery: 65–85%. TDS rejection: >98%.
Ultrafiltration
Operates at low pressure (1–4 bar). Rejects bacteria, viruses, colloidal particles, and macromolecules. Pore size 0.01–0.1 micron. Used as RO pre-treatment and for MBR STP systems. Recovery: 90–95%.
Nanofiltration & Microfiltration
NF softens water and removes divalent ions and colour. MF pre-filters turbid feeds. Used in food & beverage, textiles, and pharmaceutical applications where full desalination is not required.

Technical Specifications
Built for precision.
| Parameter | Value / Range |
|---|---|
| RO capacity range | 1 KLD – 5 MLD |
| RO TDS rejection | > 98% |
| RO permeate conductivity | 10 – 500µS/cm |
| EDI polished water conductivity | < 0.1µS/cm |
| UF flux rate | 20 – 80LMH |
| Operating pressure (RO) | 8 – 80bar |
| Membrane material | PA TFC (RO), PVDF (UF/MF) |
| Clean-In-Place (CIP) | Automated, pH 2–12 tolerance |
RO systems achieve >98% TDS rejection with permeate conductivity of 10–500 µS/cm depending on feed quality. Adding an EDI (Electrodeionisation) polishing stage brings conductivity below 0.1 µS/cm — the specification for USP purified water (PW) in pharmaceutical manufacturing. UF pre-treatment at 20–80 LMH flux rate protects RO membranes from particulate fouling, extending membrane life to 3–5 years.
