Optima Water Solutions is an EDI Systems Supplier in Coimbatore. 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 Coimbatore — Why It Matters
Coimbatore's EDI demand is limited given the city's textile and engineering-dominant economy, neither of which typically requires ultrapure water — EDI enquiries here are rare and usually tied to a specific, unusual process requirement.
Most Coimbatore clients need standard RO, NF, or UF treatment rather than EDI-grade purity.
Key industrial areas we serve in Coimbatore:
Regulatory Note: TNPCB has strict norms for Coimbatore's textile dyeing and engineering clusters. ZLD applicable to dyeing units.

Common Questions
EDI Systems in Coimbatore — FAQ
Do Coimbatore's textile or engineering sectors need EDI?
Generally no — neither industry typically requires ultrapure water. EDI enquiries here are rare and usually tied to a specific, unusual process requirement.
What does an EDI system cost in Coimbatore?
Cost typically runs ₹15 Lakh to ₹75 Lakh depending on capacity, for the rare application needing it. Call +91 9711880791 for an assessment specific to your process.
How does Optima assess EDI need for Coimbatore clients?
We review your specific process purity requirement carefully, since most Coimbatore applications are better served by standard RO, NF, or UF treatment.
What treatment does Optima usually recommend instead of EDI in Coimbatore?
For most Coimbatore clients, standard RO or UF treatment addresses their actual process water needs.
