- 4 min read
At Everfilt®, our approach has always been centered around one principle: selecting filtration media based on the specific requirements of each application rather than applying a one-size-fits-all solution, like many competitors. With the addition of Katalox-Light® to our portfolio of iron removal media, customers now have access to an expanded range of proven treatment technologies, including DMI-65® and Greensand Plus™.
Each filtration media offers unique advantages, and the ideal choice depends on factors such as water chemistry, system requirements, maintenance goals, and operating costs. By adding Katalox-Light®, Everfilt® can continue to provide more customized recommendations and engineer solutions that align with each project’s individual challenges.
Why Katalox-Lite® Was Added to Our Product Line
Water treatment requirements continue to become more complex, creating a growing need for filtration media that can manage higher contaminant levels, reduce maintenance demands, and provide broader treatment capabilities. Katalox-Light® expands Everfilt’s capabilities by offering a highly versatile media option for applications where multiple contaminants must be treated while maintaining strong filtration efficiency.
This addition does not replace DMI-65® or Greensand Plus™. Instead, it provides another effective option within Everfilt’s treatment toolbox, allowing our engineers to select the most appropriate technology based on the customer’s specific water conditions.
How Katalox-Light® Performs
Katalox-Light® is a lightweight zeolite-based filtration media enhanced with a manganese dioxide coating. This active coating supports oxidation reactions that help remove dissolved contaminants from water.
The media works through two primary processes:
Catalytic oxidation of dissolved iron & manganese
Mechanical filtration of oxidized particles
Its highly porous structure provides substantial surface area for contaminant capture, allowing for increased solids retention, longer operating cycles, and potentially fewer backwash requirements compared with some conventional media.
Applications Where Katalox-Light® Provides Advantages
High Iron Removal Applications
Katalox-Light® is well suited for water sources containing elevated iron levels where media capacity and performance consistency are important considerations.
Combined Iron & Manganese Treatment
For water containing both iron and manganese, Katalox-Light® can provide an effective single-media approach in properly designed systems.
Hydrogen Sulfide Reduction
Katalox-Light® can also assist in reducing hydrogen sulfide (H₂S), making it a strong option for well water applications affected by sulfur odors.
Arsenic Treatment Support
When used with the correct pretreatment and oxidation strategy, Katalox-Light® may contribute to arsenic reduction applications.
Fine Particle Filtration
The media’s large surface area and porous structure allow it to capture smaller precipitated particles, improving filtration performance in demanding applications.
Municipal & Industrial Systems
Katalox-Light® is particularly beneficial for systems requiring:
Extended media service life
Higher solids-handling capacity
Lower maintenance requirements
Reliable filtration performance
Comparing Katalox-Light® with Existing Everfilt® Media DMI-65®
DMI-65® continues to be a leading catalytic filtration media for iron and manganese removal, especially in systems where oxidation is already established.
It is often preferred when:
Chlorination is already part of the treatment process
Continuous oxidation is required
Municipal systems need consistent catalytic performance
Long media life is a priority
Key advantages:
Strong catalytic performance
Excellent durability
Proven results in continuous oxidation applications
Successful history in municipal treatment systems
Greensand Plus™
Greensand Plus™ remains a widely recognized and dependable technology for iron and manganese removal.
It is commonly selected for applications where:
Potassium permanganate regeneration is acceptable
Existing infrastructure uses greensand-based technology
Contaminant levels are moderate
Key advantages:
Established treatment technology
Reliable iron and manganese removal
Suitable for retrofit projects
Katalox-Light®
Katalox-Light® is especially valuable for more challenging treatment scenarios where additional filtration capacity and contaminant reduction are required, and can also provide filtration of sand, suspended solids and sediment down to 3 micron.
It may be recommended when:
Iron concentrations are elevated
Hydrogen sulfide is present
Arsenic is present
Radium is present
Radionuclides Reduction
Heavy metals reduction
Fine solids removal is needed
Longer filtration cycles are desired
Reduced backwashing is beneficial
Multiple contaminants must be addressed at the same time
Its lightweight design also simplifies handling and installation while maintaining strong mechanical durability.
How Everfilt® Selects the Right Media
Everfilt® does not simply select a media based on popularity.
Each application is evaluated using several important factors, including:
Iron concentration
Manganese concentration
Hydrogen sulfide levels
pH conditions
Dissolved oxygen availability
Oxidation requirements
Flow rates
Backwash capabilities
Maintenance expectations
Total operating costs
These variables determine which filtration media will provide the best long-term performance and value.
Everfilt’s Expanded Filtration Approach
By offering DMI-65®, Greensand Plus™, and Katalox-Light®, Everfilt® can provide more flexible and application-specific treatment solutions across agricultural, municipal, commercial, and industrial markets. This expanded selection allows our engineering team to design systems that improve efficiency, reduce maintenance requirements, and support reliable long-term operation. From a technical perspective, adding Katalox-Light® strengthens Everfilt’s ability to address complex water treatment challenges.
DMI-65® remains an excellent choice for applications requiring strong catalytic oxidation performance, while Greensand Plus™ continues to serve as a dependable solution for traditional iron and manganese removal needs. Katalox-Light® adds another level of flexibility for projects involving higher contaminant loads, combined treatment requirements, or increased filtration demands.
With its combination of catalytic activity, solids-handling capability, and ability to support iron, manganese, hydrogen sulfide, and suspended solids removal, Katalox-Light® represents a versatile addition to Everfilt’s filtration solutions. Ultimately, expanding the Everfilt® media portfolio reinforces our commitment to designing systems around each customer’s unique water challenges.
By offering multiple proven technologies, we can deliver optimized treatment solutions that improve performance, reduce lifecycle costs, and ensure every system is engineered for the application, not limited by a single filtration approach.
