Water Treatment

Water & Wastewater Treatment

Media filtration offers several key benefits and is a fundamental component of water treatment due to its ability to efficiently remove particulates, improve water quality, protect downstream processes, and offer cost-effective and versatile solutions. Its role in both municipal and industrial applications is critical for maintaining safe, clean, and reliable water supplies.

  • Particle Removal: Efficiently removes suspended solids, sediments, and particulate matter, improving water clarity and reducing turbidity.
  • Enhanced Water Quality: Eliminates contaminants like sand, silt, and organic matter, enhancing the aesthetic and safety qualities of water.
  • Protection of Equipment: Serves as a pre-treatment step, protecting and extending the lifespan of downstream processes such as membrane filtration and reverse osmosis.
  • Cost-Effectiveness: Low operational and maintenance costs, and energy-efficient operation.
  • Regulatory Compliance: Helps meet water quality standards, ensuring safe drinking water and protecting public health.

AFM® provides several key benefits over the use of conventional filter media such as Silica Sand, Expanded Clay, Zeolite and other Glass Media

  • Best filtrate quality with 1 micron particle removal up to 95% removal rate.
  • High filtration rate up to 20m/h for most applications and higher for selected applications.
  • Reduce investment and operating cost through reduced filtration surface, energy, water and chemicals cost savings.
  • Efficiency improvement of downstream treatment processes such as in MF/UF and RO membrane systems.
  • Achieve compliance with tightening water quality regulation.

AFM® Performance

Filtration performance of AFM® versus Sand at 20m/hr (8gpm/ft ) without flocculation

AFM® s Grade 0 removes 98% of particles >1μm

AFM®ng Grade 1 removes 95% of particles >1μm

AFM® s Grade 1 removes 95% of particles >4μm

High quality silica sand removes 95% of particles >20μm

  • Highly improves SDI in Reverse Osmosis (RO) membrane pretreatment, closing the gap between conventional media and MF/UF filtration
AFM® closes the gap between conventional media filtration and Ultrafiltration
  • Up to 50% water and energy savings in the backwash process highly reduces OPEX and improves plant availability

  • Stable filtration performance in industrial and municipal tertiary effluent treatment through bio(fouling)-resistant surface avoids clumping and channeling

AFM® - stable filtration (no channeling)

  • Stable filtration performance in industrial and municipal tertiary effluent treatment through bio(fouling)-resistant surface avoids clumping and channeling

Sand - instable filtration

  • Reduced coagulant, flocculant and disinfection chemical dosing (e.g. chlorine) saves OPEX and reduces DBP and THM formation in conventional and advanced (e.g. desalination) drinking water treatment processes.
  • No free silica in AFM® (unlike silica sand), protects and improves performance of downstream processes such as in UF/MF and RO membrane and Ion Exchange (IX) systems
  • Efficient iron & manganese (oxide) and organics removal through unique AFM® surface properties for improved ground, surface and wastewater treatment

AFM® NG: HYDROPHOBIC SURFACE

Superior mechanical filtration performance, combined with efficient removal of hydrophobic contaminants. In soft water AFM®ng performs better than sand or AFM®s.
  • Best filtration & organics removal

AFM® S: HIGH NEGATIVE SURFACE CHARGE

Robust and stable, high filtration performance media with a 20 year track record. Best suited for the removal of positively charged particles such as heavy metals (e.g. Iron, Manganese and Arsenic).

  • Best for heavy metals removal
