Optima Water Solutions supplies and installs Electrodeionization (EDI) Systems in Nagpur for ultrapure water production used in pharmaceutical, semiconductor, power, and high-purity chemical manufacturing. Our ISO 9001:2015 certified EDI systems eliminate 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 Nagpur — Why It Matters
Facilities operating near MIDC Butibori, MIDC Hingna, MIHAN SEZ in Nagpur face close scrutiny over wastewater discharge. MPCB regulates industries in Nagpur. MIHAN SEZ has strict environmental compliance requirements. ETPs mandatory for all industrial units. STPs required for large housing societies and commercial complexes.
Optima Water Solutions has built a track record of EDI installations serving Nagpur and the surrounding area, with local support for commissioning, operator training, and ongoing maintenance.

Common Questions
EDI Systems in Nagpur — FAQ
What is the cost of an EDI System in Nagpur?
EDI system cost in Nagpur depends on capacity and application. A 100 LPH pharmaceutical EDI system starts from ₹5–8 Lakh. A 1 m³/hr industrial EDI costs ₹15–25 Lakh. Large 10 m³/hr systems for power or semiconductor use range ₹80 Lakh to ₹2 Crore. Call +91 9711880791 for specifications and pricing.
What is the difference between EDI and DM Plant?
A DM (Demineralisation) plant uses cation and anion exchange resins regenerated periodically with HCl and NaOH. EDI uses continuous electrochemical regeneration — no chemicals needed, no downtime for regeneration, consistent output quality. EDI produces higher purity water (10–18 MΩ·cm vs 1–5 MΩ·cm for DM) with lower long-term operating costs.
Does EDI meet USP Purified Water requirements?
Yes. A properly designed RO + EDI system consistently meets USP Purified Water specifications — conductivity below 1.3 µS/cm at 25°C, TOC below 500 ppb, and microbial limits. Optima provides full IQ/OQ/PQ validation documentation for pharmaceutical EDI installations in Nagpur.
What pre-treatment does EDI require?
EDI requires RO permeate as feedwater — typically RO output with conductivity below 30 µS/cm. Free chlorine must be absent (use activated carbon or sodium bisulphite dosing). CO2 should be removed using a degasser. Hardness must be below 1 ppm. Proper pre-treatment ensures EDI module life exceeds 5–7 years.
Can you retrofit EDI to an existing RO system in Nagpur?
Yes. If you have an existing RO system in Nagpur, Optima can add an EDI polishing module to upgrade output water quality to ultrapure standards. We assess your existing RO output quality and design the EDI integration — including any additional pre-treatment needed before the EDI module.
