Features
1-Micron Filtration Clarity
Achieves filtration down to 1 micron without additional chemical coagulation, delivering finer water clarity than conventional sand media.
Anti-Biofouling Surface
A self-sterilizing surface prevents bacterial growth and channeling, keeping the filter bed performing consistently over time.
Direct Sand Replacement
Installs into any existing sand filter vessel without modification, simplifying upgrades to existing filtration systems.
Reduced Backwash Water Demand
Cuts backwash water consumption by an average of 50%, lowering water usage and operating cost per filtration cycle.
Superior Fine Particle Retention
Retains more than double the fine particulate load of any other filtration media, improving downstream water quality.
Heavy Metal & Metalloid Adsorption
An engineered surface adsorbs fine particles, heavy metals, and metalloids including arsenic, extending treatment beyond simple solids removal.
Extended Service Life
Rated for a service life of up to 15 years, with a life cycle more than 4 times longer than conventional sand media.
Membrane Life Extension
Improves the operating life of downstream RO/UF membranes by reducing fouling load reaching the membrane stage.
Certified for Municipal & Drinking Water Use
Certified under ISO 9001:2015, ISO 14001, ISO 18001, HACCP, NSF50, European DWI Reg 31, and NSF61 for drinking water applications.
Outcomes
Improved Treated Water Clarity
Filtration down to 1 micron without chemical coagulation delivers a higher standard of water clarity than conventional sand filtration.
Lower Water Consumption
An average 50% reduction in backwash water demand directly reduces water consumption per filtration cycle.
Extended Filter Media Life
A service life of up to 15 years — more than 4 times that of sand — reduces the frequency of media replacement.
Extended Membrane Life (RO/UF)
Reduced fouling load reaching downstream RO or UF membranes helps extend membrane operating life.
Reduced Fouling and Channelling
The self-sterilizing, anti-biofouling surface resists bacterial growth and the channeling problems associated with biological fouling in sand filters.
Reduced Oxidation Demand
Substantially reduces product water oxidation demand, supporting more efficient downstream disinfection or oxidation processes.
Faster Return on Investment
Typically delivers a return on investment in under 2 years based on water consumption savings alone.
Heavy Metal and Metalloid Removal
Adsorbs fine particles along with heavy metals and metalloids such as arsenic, supporting compliance with potable and process water quality standards.
About
AFM (Activated Filtration Media) is an engineered granular filtration medium developed as a high-performance alternative to sand in mechanical filtration systems. It is designed as a direct, drop-in replacement that works within existing conventional sand filter vessels without requiring any modification, making it straightforward to retrofit into operating plants. The media's engineered surface delivers filtration down to 1 micron without the need for additional chemical coagulation, and provides more than double the fine particle retention performance of standard filtration media. Its self-sterilizing surface resists bacterial growth and the channeling that biological fouling causes in conventional sand beds, while its adsorptive surface captures fine particles, heavy metals, and metalloids including arsenic. With a service life of up to 15 years — more than four times that of sand — and certification for use in municipal and drinking water applications, AFM is positioned as a long-life, low-maintenance filtration upgrade for industrial and municipal water treatment systems.
Process
Feed water passes through a filter bed of AFM media, installed in the same configuration as a conventional sand filter, with no modification to the filter vessel required. As water flows through the engineered granular bed, the media mechanically filters particulates down to 1 micron and adsorbs fine particles, heavy metals, and metalloids such as arsenic on its engineered surface. The self-sterilizing surface of the media resists bacterial colonization during operation, preventing the biofouling and channeling that reduce the performance of standard sand media over time. Periodic backwashing clears retained solids from the bed, with AFM requiring an average of 50% less backwash water than sand to restore filtration capacity, before the media returns to service for the next filtration cycle.
Unique Benefits
Industrial Use Cases

Upgrade & Retrofit Applications
Confirmed Applications (Supported by Product Data)
- Direct replacement for sand in any existing conventional sand filter, with no modification required to the filter vessel.
- Retrofit media for RO/UF pre-treatment stages to reduce fouling load and extend membrane life.
- Upgrade media for cooling tower side-stream filters, municipal/corporation water supply filters, swimming pool filtration systems, and effluent tertiary treatment filters.
General Compatibility Considerations
- Because AFM is designed as a drop-in sand replacement, it is broadly applicable to plant modernization projects seeking improved filtration performance, reduced backwash water consumption, or longer media life without replacing existing filter infrastructure. Specific system sizing and expected performance should be confirmed against the existing filter vessel design and feed water characteristics.
