Optima Water Solutions is an EDI Systems Supplier in Delhi NCR. We supply and install Electrodeionization (EDI) Systems for ultrapure water production used in pharmaceutical, semiconductor, power, and high-purity chemical manufacturing. Our ISO 9001:2015 certified EDI systems remove the need for chemical regeneration, producing consistently high-purity water (resistivity 10–18 MΩ·cm) with minimal environmental impact.
What is a EDI Systems?
Electrodeionization (EDI) is a continuous electrochemical ion exchange process that uses ion exchange membranes, resins, and a DC electric current to remove dissolved ionics from water — producing ultrapure water without the chemical regeneration required by conventional ion exchange (DM plant) systems.
EDI operates as a polishing step after Reverse Osmosis (RO) to produce high-purity water meeting USP Purified Water, ASTM Type I/II, and semiconductor grade specifications. Output water typically has resistivity of 10–18 MΩ·cm and TDS below 0.1 ppm.
Key advantages over conventional DM plants: no acid/alkali regeneration chemicals, continuous 24/7 operation, consistent output quality, and lower hazardous waste.
EDI Systems in Delhi NCR — Why It Matters
NCR's EDI demand comes primarily from pharmaceutical and electronics clients needing ultrapure water beyond what RO alone achieves, typically as the final polishing stage after RO in a multi-step treatment train.
Given the limited number of true EDI applications compared to standard RO demand, we assess each NCR enquiry carefully to confirm EDI is genuinely needed rather than a less complex RO-plus-mixed-bed system.
Key industrial areas we serve in Delhi NCR:
Regulatory Note: The Delhi Pollution Control Committee (DPCC) and CPCB have issued strict norms for all industries and large residential projects in Delhi. Non-compliant units face closure orders. All Optima systems are designed to meet current DPCC and CPCB discharge standards.

Common Questions
EDI Systems in Delhi NCR — FAQ
Do most NCR facilities need EDI, or is RO sufficient?
Most facilities only need RO — EDI is reserved for applications needing ultrapure water beyond RO's capability, typically pharma or electronics manufacturing. We assess your specific purity requirement before recommending EDI.
What does an EDI system cost in NCR?
Cost typically runs ₹15 Lakh to ₹80 Lakh depending on capacity and purity specification. Call +91 9711880791 for an assessment specific to your application.
How does EDI fit into an NCR facility's treatment train?
EDI typically serves as the final polishing stage after RO, removing residual ions to reach the ultrapure water standard your process requires.
Does Optima install and maintain EDI systems in NCR?
Yes, we handle design, installation, and AMC support for EDI systems across the NCR region.
