Optima Water Solutions is an EDI Systems Supplier in Kolkata. 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 Kolkata — Why It Matters
Kolkata's EDI demand is limited given the city's economic mix, concentrated among select chemical processing units in Dankuni and Falta needing ultrapure water for specific applications.
Most Kolkata industrial clients don't need EDI-grade purity, making standard RO sufficient for the majority of enquiries.
Key industrial areas we serve in Kolkata:
Regulatory Note: West Bengal Pollution Control Board (WBPCB) mandates ETPs for industries and STPs for large housing projects in Kolkata.

Common Questions
EDI Systems in Kolkata — FAQ
Is EDI commonly needed in Kolkata?
Less often than pharma-heavy cities like Hyderabad — demand is limited to select chemical processing units in Dankuni and Falta needing ultrapure water for specific applications.
What does an EDI system cost in Kolkata?
Cost typically runs ₹15 Lakh to ₹75 Lakh depending on capacity and purity specification. Call +91 9711880791 for an assessment specific to your process.
How does Optima assess EDI need for Kolkata clients?
We review your specific process purity requirement — EDI is only recommended where standard RO genuinely can't meet the specification.
Does Optima have EDI experience relevant to Kolkata's industries?
Yes, though our Kolkata EDI project volume is smaller, we bring the same process-specific design approach to any unit that genuinely needs it.
