PURELAB Pulse's EDI technology

Continuous electrodeionization

Continuous Electrodeionization (EDI, Electrodeionization) is an advanced green water treatment technology that combines electrodialysis technology, ion exchange (IX) technology and cation and anion selective membranes. The pure water treated by the reverse osmosis membrane enters the EDI module. Under the action of the electric field, the ions in the water migrate directionally in the resin, and the membrane is permeable through the anode and the anion. These ions are concentrated in concentrated water, and the concentrated water can be discharged or recycled. Deionized water from the EDI module can be used directly or further processed.

PURELAB Pulse
The PURELAB Pulse pure water system is equipped with the advanced patented "Pulse" module. The pure water system uses tap water as the influent water to produce II+ grade pure water. The tap water first enters the pretreatment column (activated carbon) to remove chlorine, then removes most of the impurities through the reverse osmosis membrane, and then removes the hardness through the softening column, and finally passes through the sterilization UV lamp and the Pulse (EDI) module. Water can be taken from the water distribution tap on the pure water system, or pure water can be circulated between the (dock type) water tank and the system. The water passes through the UV lamp and the “Pulse” module during the cycle, ensuring high water purity.

Workflow of PURELAB Pulse pure water system

The advantages of the ELGA "Pulse" module and the unique internal circulation design of the pure water system ensure a long-term stable production of high-quality water.

Benefits of the Pulse module
• Unique interior design and process: Optimized combination of a range of anionic, cationic and mixed bed resin compartments (known in the industrial water purification industry) to produce ultrapure water.

• EDI technology continuously regenerates the resin by hydrogen ions and hydroxide ions generated by water electrolysis. Therefore, the EDI module can continuously produce high-quality ultra-pure without regeneration of acid and alkali chemicals. The water quality is always guaranteed.

• Overcome the adverse effects of depletion of the resin bed. For example, silicon, boron or organic matter in water can't be removed beyond the resin load; saturated resin will suddenly release boron, silicon and organic pollutants into the water; new resin will be used Release organic matter into the water.

• The Pulse module of the PURELAB Pulse pure water system uses low voltage power and has a voltage of approximately 12 volts to ensure low power consumption.

• ELGA testing and experience have shown that the pH of the cation exchange resin and the anion exchange resin zone vary greatly, and the water undergoes rapid changes in pH as it flows through the different resins, thereby significantly keeping the bacterial content to a minimum. (See " Bactericidal Effects of EDI Technology in PURELAB Pulse ").

Benefits of the PURELAB Pulse Process
• In working mode, the water from the tank circulates through the 254nm UV lamp and the Pulse module to ensure water quality. Due to the unique location of the Pulse module in the circulation line, no deionization column is required. The system's water production is usually >10 MΩ-cm. If it is used as ultra-pure water, the water produced by the ultrapure water system can easily reach 18 MΩ-cm.

• The RO production water and water in the tank are mixed and passed through a 254 nm UV lamp and Pulse module to ensure that the Pulse module is always operating at its best. Even if the influent water quality fluctuates in a short period of time, the Pulse module can effectively remove ions, so it does not significantly reduce the water quality.
