Inversand Manganese Greensand Plus vs DMI65: Which to Choose for Your Water Treatment?

Are you looking for the best solution for efficient and cost-effective water treatment? If yes, you might be wondering, "Inversand Manganese Greensand Plus vs DMI65, which one is better?"This article will discuss the comparison between Inversand Manganese Greensand Plus and DMI65 to help you make an informed decision.

What is Inversand Manganese Greensand Plus?

Inversand Manganese Greensand Plus is a highly effective water filtration media for removing iron, manganese, and hydrogen sulfide from water. This media contains greensand minerals that are rich in manganese oxide, which helps in the oxidation and filtration process. One of the main advantages of Greensand Plus is its ability to perform well at low pH and does not require a large backwash pump, making it more energy and operational cost efficient.

Excellence of Inversand Manganese Greensand Plus

1. Based on data from both PDFs, here are the advantages of Greensand Plus compared to DMI-65:

   1. Ability to Remove Multiple Contaminants

   • Greensand Plus: Has the ability to remove not only iron and manganese, but also hydrogen sulfide, arsenic, and radium. This makes it more versatile than DMI-65, which is primarily focused on removing iron and manganese only
   • DMI-65: Primarily effective for iron and manganese removal, but not specifically designed to address contaminants such as hydrogen sulfide, arsenic, or radium
   • DMI-65.

   2. Tolerance to Operating Conditions

   • Greensand Plus: Can operate at higher temperatures without a specified maximum limit, and can withstand higher pressure differentials. This provides more flexibility in a wide range of operational conditions and allows for longer operating times between backwash cycles.
   • DMI-65.
   • DMI-65: Has a maximum operating temperature of 113°F (45°C), which can be a limitation in certain applications.
   • DMI-65.

   3. Ease of Maintenance and Operation

   • Greensand Plus: It does not require a long startup period or extensive preconditioning, which allows the system to immediately achieve the desired water quality. In addition, regeneration with potassium permanganate provides a simple maintenance option.
   • DMI-65.
   • DMI-65: Although it does not require chemical regeneration, the use of DMI-65 requires consistent chlorination to maintain its effectiveness, which can require more stringent management and monitoring
   • DMI-65.

   4. Flexibility in System Design

   • Greensand Plus: Can be used in different types of filter systems, both vertical and horizontal, as well as in gravity filter systems. This gives more options in terms of water treatment system design and configuration'
   • DMI-65: While also flexible, system designs that require lower flow velocities to optimize manganese removal may limit design choices in some cases.
   • DMI-65.
    

What is DMI65?

DMI-65 is a catalytic filtration media used in water treatment for iron and manganese removal. The media is designed with an infusion technology that incorporates strong oxidizing agents into the microporous structure of its matrix material. This infusion technology increases the catalytic surface of the media, thus enabling high oxidation rates.

Key Differences between Inversand Manganese Greensand Plus and DMI65

1. Media Composition and Technology

• Greensand Plus: Made of a silica sand core coated with manganese dioxide. This coating acts as a catalyst in the oxidation-reduction reaction of iron and manganese. This media allows the removal of various contaminants such as iron, manganese, hydrogen sulfide, arsenic, and radium.
• DMI-65: Uses an infusion technology where strong oxidizing agents are infused into the microporous structure of its material matrix. This technology gives DMI-65 a higher oxidation rate and greater charge capacity for efficient removal of iron and manganese
• DMI-65.

2. Regeneration and Maintenance

• Greensand Plus: Requires regeneration with potassium permanganate (KMnO₄) to maintain its effectiveness in contaminant removal. This means regular treatment with chemical additives is required
• DMI-65: Does not require chemical regeneration, as this media is activated and maintained through a chlorination process. This reduces the need for regular chemical treatments, making it easier in terms of long-term maintenance
• DMI-65.

3. Application and Effectiveness of Contaminant Removal

• Greensand Plus: Highly effective in removing iron, manganese, hydrogen sulfide, arsenic, and radium, making it a more versatile choice for a variety of water treatment applications.
• Greensand Plus.
• DMI-65: Focused on iron and manganese removal, with optimal performance at a specific pH (5.8 to 8.6) and not specifically designed to remove other contaminants such as arsenic or radium. DMI-65 can also address higher levels of iron, with the ability to remove up to 15 ppm iron and up to 3 ppm manganese.

4. Operational Conditions

• Greensand Plus: Has an operating pH range of 6.2 to 8.5 and has no maximum temperature limit, making it flexible for a wide range of water conditions and temperatures.
• Greensand Plus.
• DMI-65: Operates in a pH range of 5.8 to 8.6 with a maximum temperature limit of 113°F (45°C). This makes it more limited in applications that require higher operational temperatures.
• DMI-65.

5. Flow Speed and Operating Pressure

• Greensand Plus: Recommended to operate at flow rates of 2 - 12 gpm/sq.ft (4.9 - 29.4 m/hr), with tolerance to higher pressure differentials, allowing for longer operating times between backwashes.
• DMI-65.
• DMI-65: Has a service flow rate of 5 - 30 m³/m² per hour, with a backwash expansion range of 20% - 50%. This media is designed to reduce backwashing frequency and improve operational efficiency.
• DMI-65.

Conclusion

In a comparison between Inversand Manganese Greensand Plus vs DMI65, Greensand Plus proved to be more efficient and cost-effective. By not requiring chlorine dosing and requiring lower flow backwash, Greensand Plus is a better choice for your water treatment.
