Why isn't my DI resin reading 0 TDS? Could it be defective?

Firstly, it's crucial to recognize that the lifespan of resin is relatively short. Any incorrect setup or application can lead to brief periods of 0 PPM output, typically lasting only 1 to 2 minutes. Therefore, it's imperative to meticulously follow instructions to grasp the resin's functionality and make an informed decision about investing in such systems.

When DI resin fails to produce water with zero Total Dissolved Solids (TDS), there are various potential causes. Let's explore some common reasons behind this issue:

1.      Resin Exhaustion: DI resin becomes exhausted and loses its effectiveness over time or after processing a significant volume of water. Check usage against recommended PPM guidelines for replacement.

2.      Improper Usage: The lifespan of resin is brief, and any incorrect setup or application can lead to short periods of 0 PPM output. Follow instructions meticulously to thoroughly grasp the resin's operation before investing in such systems.

3.      Car Washing Technique: Avoid using DI water for washing cars directly; instead, wash with regular tap water and use DI water for a final rinse. Neglecting this step can lead to dissatisfaction with system performance.

4.      Optimal DI Water Usage. Efficient Use of the Mist Valve

-       Control DI Water Flow: Utilize the mist valve to efficiently control the DI (Deionized) water flow rate

-       Minimize Water Usage: Adjust the valve to the lowest possible flow rate to reduce DI water consumption.

              Benefits of Proper Usage

-       Prevent Excessive Consumption: Without the mist valve, there is a risk of excessive DI water consumption during car washing, which can lead to premature exhaustion of the DI water supply.

-       Maintain Low PPM Levels: A high flow rate can increase the PPM (parts per million) reading of the water, reducing its effectiveness. If water passes through the resin too swiftly (fast flow), insufficient contact time for ion exchange can result in lower purity water output (resulting in a High PPM reading).

             Recommendations for Optimal Performance

-       Use Two DI Filters in a Series: For the best results, particularly in areas with PPM readings of 150 and higher, it is crucial to use two DI filters in a series. This setup helps bring the PPM reading close to zero, ensuring optimal water quality.

-       Achieve Zero PPM: For customers with high initial PPM readings, achieving a PPM reading of zero with this system is essential for maintaining the quality and efficiency of the car wash process.

6.      Water Temperature and Composition: Elevated temperatures and specific ions or chemicals in the water can influence ion exchange efficiency, requiring careful consideration.

7.      Proper Packing and Channeling: Inadequate resin packing or channel formation within the container can hamper effective ion exchange, potentially due to settling or improper filling.

8.      Contamination or Degradation: Resin can be compromised by various contaminants or undergo physical degradation, impacting its functionality. Mechanical wear and chemical exposure, such as from chlorine, can contribute to this.

Where to Store DI Mixed Bed Resin Media:

1.      Cool Environment: Store the resin in a cool, reasonably dry place. Ideal storage temperatures are between 10°C and 25°C (50°F and 77°F). Avoid extreme temperatures, especially heat, which can degrade the resin.

2.      Dry Location: Keep the resin away from direct sunlight and excessive moisture. High Humidity can affect the resin’s quality and performance.

3.      Well-Ventilated Area: Ensure the storage area is well-ventilated to prevent condensation and mold growth.

4.      Away from Chemicals: Store away from strong oxidizing agents, acids, bases, and other chemicals that can react with the resin.

How to Store DI Mixed Bed Resin Media:

1.      Keep it Away from Children.

2.      Sealed Containers: Keep the resin in airtight, sealed containers or bags to prevent exposure to air and moisture. Original packaging is often the best option if it is resealable.

3.      Avoid Freezing: Ensure the resin does not freeze, as freezing can cause physical damage to the resin beads, impacting their performance.

4.      Proper Labeling: Clearly label the containers with the type of resin, and date of purchase. This helps maintain an inventory and ensures the oldest resin is used first.

5.      Limited Exposure: Only open the containers when necessary and reseal them immediately after use to minimize exposure to air and contaminants.

6.      Regular Checks: Periodically check the condition of the resin if stored for extended periods. Look for signs of discoloration, moisture, or any other indication of degradation.

To address your specific situation, evaluate factors like flow rate, resin condition, and water composition, and consider replacing exhausted resin if necessary. Always ensure that your TDS meter is calibrated and reading correctly.
