How NEWater EDI Water System Works

Our system’s processes are set in action when flow enters the resin-filled diluting chamber. The resins in the mixed bed scavenge strong ions from the feed stream. Charged ions are dragged off the resin and attracted towards the corresponding, oppositely-charged electrodes These charged strong-ion species are continually removed and transported into the adjacent concentrating compartments.

The high electrical potential divides water at the resin beads’ surface, resulting in hydrogen and hydroxyl ions. These serve as ion-exchange resin regeneration agents. These regenerated resins enable the ionization of aqueous species that are neutral or weakly ionized. After ionization, the ions are removed using direct current and ion exchange membranes.

The Ultimate FAQ Guide for Electrodeionization (EDI) Water Systems

The growth of industries reliant on ultrapure water has recently surged consequently hiking the demand for water purification systems. Electrodeionization water systems are one of the most effective water treatment systems hence the widespread adoption in first-rate industries recently.

EDI is a high-end water treatment solution often deployed in collaboration with other treatment technologies. Owing to its resourcefulness, Electrodeionization is steadily replacing mixed-bed ion exchange as the chief solution to ionic pollutants.

Figure 1 Electrodeionization water system.

What are the Basic Features of EDI Water Systems?

Electrodeionization water systems are uniquely built and function uniquely thanks to their outstanding components and functional capabilities. NEWater employs cutting-edge innovation to manufacture outstanding EDI water systems that guarantee high purification scores and cost-efficiency. Below, we summarize the basic features that make our Electrodeionization water plants stand out from the rest.

  • Conventionally lightweight and compact designs.
  • High-quality product water (up to 18 MΩ-cm).
  • Deionization is powered by DC power and not caustic chemicals.
  • Continuous regeneration.
  • The average flow rate ranges from 1 GPM to 600 GPM.

What are the Advantages of Using Electrodeionization (EDI)Water Systems?

The innovation of electrodeionization water systems is largely perceived as a game-changer in water treatment. EDI water systems guarantee continuous production of ultrapure water at seemingly cheaper rates compared to other water treatment technologies.

Electrodeionization is commonly referred to as the green water treatment solution because it does not rely on chemicals and thereby does not generate perilous waste. Additional benefits arising from the use of electrodeionization water systems include:

  • Continuous generation of ultrapure water.
  • Power-efficiency.
  • They use low voltages, which are largely safer.
  • EDI modules are compact thereby occupying a lesser footprint.
  • They are easy to set up and simple to operate.

What Options are Ideal for Electrodeionization Water Systems?

Electrodeionization(EDI) water systems function optimally when utilized in tandem with other water treatment systems. The choice of supplementary water treatment options to utilize with electrodeionization depends on the desired quality of product water.

For instance, the use of a single-pass reverse osmosis system tailed by electrodeionization generates product water with a resistivity of 17 megaohms. Underneath are various options that will definitely improve the quality of potable water generated by your EDI water system.

  • A combination of water softener, reverse osmosis, and finally Electrodeionization modules.
  • A combination of water softener, RO unit, membrane degasser, and finally EDI module.
  • Reverse osmosis with chemical dosing then reverse osmosis and finally Electrodeionization.

What are the Advantages of Using Two-Pass RO in Collaboration With EDI Systems?

To generate ultrapure water using electrodeionization, it is recommended that you first deploy a water softener and reverse osmosis processes. Many industries opt for one-pass reverse osmosis as the primary water treatment process because of its effectiveness and cost-efficiency. However, the demand for higher-quality purified water may necessitate the use of two-pass reverse osmosis prior to electrodeionization. This process has the following benefits.

  • Reduced CO2 Levels.
  • Elevated flow rates in Electrodeionization water systems.
  • Minimizes the frequency of cleaning EDI water plants.

What is the Average Cost of Electrodeionization Water Systems?

Comparatively, electrodeionization water systems are relatively inexpensive to set up and operate. Although the general capital costs of EDI water systems are comparable to those of mixed-bed IX systems, EDI units tend to be relatively inexpensive given they consume 95% fewer chemicals. However, electrical bills substitute expenditure on chemicals.

Other contributing factors that influence the operational costs of EDI systems include equipment installation, labor charges, repairs, and maintenance. Labor charges vary depending on your respective country’s labor regulations while maintenance charges are relatively low given there is no frequent need for resin replacements.

The other primary aspect of EDI systems’ cost is the purchasing price of the necessary equipment. The prices show discrepancies based on size, flow rate, and system design.

What Factors Should I Consider When Procuring an EDI Water System?

Buying EDI water systems demands a certain level of knowledge of EDI equipment and processes. In your quest to acquire a reliable electrodeionization water plant, factoring in the following variables will aid you to make the perfect purchase.

Desired Flow Rate

Different applications have distinct processing targets. Therein, you first need to determine your projected flow rate and compare it to the available EDI water systems. Available options vary from 1 GPM to 2000 GPM, with basic categorizations being minimum, moderate, and maximum.

Feed Water Quality

Prior knowledge of your feed water’s composition and concentration is a key determinant of the ideal Electrodeionization system. Different EDI units are differently suited for distinct qualities of feed water. Key considerations include water hardness, silica concentration, C02 levels, and dissolved constituents.

Targeted Potable Water Quality

You probably need an EDI water unit because your enterprise needs high-grade purified water that meets certain thresholds. Your imminent system should have the capacity to produce your desired product water over a long period.

Does Electrodeionization Eradicate CO2 From Raw Water?

Yes. CO2 elimination is one of the key advantages of using electrodeionization water systems. Most water treatment systems including reverse osmosis are limited when it comes to CO2 removal hence the use of EDI as a polishing process. Determining the level of CO2 present in water is quite difficult given its existence in water is ionized. Measuring the water’s conductivity does not necessarily establish the concentration of carbon dioxide in the water.

Figure 7 Electrodeionization.

What Types of Feed Water Can be Treated Using Electrodeionization?

The primary feed water for electrodeionization water systems is reverse osmosis permeate. For optimal water treatment, the feed water meant for EDI must be adequately pretreated using water softener systems, reverse osmosis, chemical dosing, or membrane degasser.

Certain applications utilize various combinations like water softening, reverse osmosis, and membrane degasser to pretreat EDI feed water. Essentially, electrodeionization water systems can treat virtually all forms of feed water as long as adequate pretreatment is deployed.
