AFM® has much better fine particle retention than sand. It also reduces fouling because it does not contain free silica that cause silicate blockage. AFM® resists biofouling and does not become a biofilter.
Removal of arsenic, ferric, and manganese
AFM® will remove many metal contaminants from the water, and is particularly effective for arsenic and ferric. Contamined water is usually ground water which must be strongly aerated for a period of at least 30 minutes prior to filtration
Cooling tower side-stream filtration
Water treatment is essential for cooling tower recycled water. AFM® removes nutrients to control pathogenic bacteria such as Legionella thereby reducing requirement for corrosion inhibitors, biocides, and anti – scalants by up to 50%
Tertiary treatment of effluent
AFM® replaces sand in tertiary treatment filters without the need for any modifications. AFM® will not bio foul and will more than double the performance of the treatment system, offering a sustainable, low cost, and high performance alternative to sand
