Deionization is the removal of mineral ions by using the ion exchange process. Using a mixed bed of anion and cation resins such as the IONPLUS MB-30, ions, salts and minerals can be entirely removed from the water.
If you use a RO membrane, the RO membrane has a direct impact on the life-span of the DI. The RO membrane can remove about 95-99% of TDS (minerals) in your water. When a deionization filter is used after the RO membrane, you can expect almost 100% removal of the TDS.
Excellent media for deionization of water for industrial, aquatic, and other water treatment applications.
All naturally-occurring water contains dissolved mineral salts. In solution, salts separate into positively-charged cations and negatively-charged anions. Deionization can reduce the amounts of these ions to very low levels through the process of ion exchange. Cations are removed by cation exchange resin. It replaces sodium, calcium, magnesium, and other cations with hydrogen ions (H). This exchange produces acids which must be removed or neutralized by anion exchange resin.
The IonPlus MB-30 is virgin resin. It is not used or regenerated resin.
Ion exchange resins may be safely stored for prolonged periods of time in areas where the ambient temperature is between 4-40°C (41-104°F).
Following these precautions, there should be little or no concern regarding the shelf life of the resins being stored. Physical damage of ion exchange resins due to dehydration may occur in cases of extreme moisture loss during storage.
Before any resin stored for prolonged periods of time is placed into service, it is always considered good practice to soak the resin in saltwater for a few hours. The rehydration process allows the ion exchange resins to swell back to their original volume slowly and to release any occluded air from the resin structure.
In rare cases, it may be necessary to store ion exchange resins in their less stable forms. In these instances, it is important that precautions be taken to assure that the ion exchange resins are properly stored in a hydrated condition at temperatures, which rarely exceed 40°C (104°F) for prolonged periods of time.
During the shipment to and storage in areas where temperatures drop below 0°C (32°F), storage precautions should be taken to avoid subjecting ion exchange resins to repeated freezing-thawing conditions. Although a few freeze-thaw cycles are generally harmless, repeated freezing-thawing of ion exchange resins, regardless of the forms in which they are supplied, could bring about physical attrition of the ion exchange resin by physically breaking the resin beads. Generally recommended Rules of Thumb are that un-regenerated resins be used within five years, regenerated resins used within one year, and low TOC grade resins within a month or two.
Why my DI resin is not reading 0, is there a defective resin?
Deionization (DI) resin that doesn’t produce water with a zero Total Dissolved Solids (TDS) reading could be due to several factors. Here are some common reasons why DI resin might not perform as expected:
- Exhaustion of Resin: DI resin can only remove a finite amount of ions from water before it becomes exhausted and needs to be regenerated or replaced. If the resin has been in use for a significant period or has processed a lot of water, it may simply be exhausted.
- Poor Packing or Channeling: If the resin isn’t packed tightly in its container, channels can form where water flows through the resin bed without proper contact, reducing the effectiveness of ion exchange. This can happen if the resin settles or if it wasn’t filled properly.
- High Water Flow Rates: If water flows through the DI resin too quickly, there isn’t enough contact time for the ion exchange process to occur effectively. This can result in lower-purity water.
- Contamination or Degradation of Resin: The resin can be contaminated by oils, organic compounds, or other chemicals that interfere with ion exchange. Physical degradation from mechanical wear or chemical attack (like from chlorine or other oxidants in the water) can also reduce its effectiveness.
- Incorrect Resin Type or Mixture for your application: Using the wrong type of resin, or an incorrect mix of cation and anion exchange resins, could also result in less effective ion removal.
- Temperature and Chemical Composition of Water: Higher temperatures can affect the efficiency of ion exchange. Additionally, the specific ions and chemicals in the water being treated can impact performance. Certain ions might be more difficult to remove or might require specific types of resin.
To troubleshoot your specific situation, you might consider checking the flow rate, inspecting the resin for signs of channeling or degradation, testing the incoming water to see if there’s a particularly high ion concentration, or replacing the resin if it’s old or exhausted.
