EDI

High Purity Water Generation System & Distribution Loop System

High Purity Water Systems Manufacturers

The Electrode ionization (EDI) process is a continuous, chemical-free method that removes ionized and ionizable impurities from the feed water. EDI is most used to treat Reverse Osmosis (RO); permeate and replace Mixed Bed (MB) ion exchange; producing high purity water of up to 18 M Ω.cm. EDI eliminates the need to store and handle hazardous chemicals required for resin regeneration and the associated neutralization steps.

Pharmaceutical grade water system featuring hot water sanitization ability at 85°C. These stacks can produce high purity water quality up to 18 MΩcm using a patented process with double sets of electrodes per stack.  These stacks have widespread application in Pharmaceutical, Biomedical & Laboratories where hot water sanitization is required.

Electrode ionization (EDI) Systems Ultrapure Systems

Advantages OF EDI Systems:

• low TOC value.
• Cost effective.
• Produces from 1 µS/cm high purity water to 18 MΩ cm ultra-pure water with very low levelsof silica & boron
• Low bacterial count
• Low Power Consumption
• Easy to Operate
• Capable of generating ultra-pure water without having to discharge chemical laden regeneration waste streams
• No down time as no regeneration is required
• Standby units not required
• Produces consistent and continuous desired water quality

High Purity Electrode ionization systems are used for a wide variety of applications including critical boiler make-up, microelectronics, and critical purity manufacturing. These systems are available in a range of capacities and can be furnished as containerized or skid-mounted systems.
