Description
AFM® is one of the most efficient granular filtration medium available on the market. It is highly engineered to give optimum mechanical filtration performance in a range of industrial and municipal water filtration applications.
AFM® replaces sand in all filtration applications and can be used in a conventional sand filter without modification.
AFM® is manufactured from very specific green and brown glass types
• Engineered to obtain optimum and consistent particle size and shape
• Activated to increase the surface area up to 300 times of that of crushed glass or sand.
• Chemically and thermally treated to ensure permanent negatively charged surface properties that make
AFM® self-sterilising and will not support bacterial growth and prevents bio fouling which reduces channelling.
Selectively filter positively charged ionic particles such as heavy metals • will not suffer from channelling or preferential pathways • will consistently evacuate more than 95% of retained particles using 50% or less water than required for sand. (backwash duration 5 mins max at 45m/h). • has a minimum service lifespan of 10 years or more.
NSF61 certified for Drinking water
It’s also the only activated glass that is not just recycled glass
pH limits 4 – 10 pH
21kgs of AFM® is equivalent to 25kgs of sand in volume. As a guide the AFM glass 1kg = 1.2 litres in volume.
Grade 1 is 0.4mm – 1mm
Grade 2 is 1mm – 2mm
Grade 3 is 2mm – 4mm
Different grades can be used in layers to achieve a graded depth filter.
Best practice backwash of new AFM® in large vessels is 5 minutes, 3 consecutive times, with potable water and then rinse for 5 minutes.
Sold by the Kg and discounts apply for 21Kg’s or more
If you require a large quantity order in increments of 21kg’s as bulk bags are 21kgs each
