Nanofiltration (NF)
Aslan’s NF systems are available in custom configurations for use in industrial and potable water purification applications. These filters reject particles in the 0.001 - 0.01µm range to filter suspended solids, most organic molecules, and a percentage of dissolved salts.
Similar to RO, Nano Filters have a high rejection of divalent salts such as calcium and magnesium - which are responsible for hardness in water - but have lower rejection of monovalent salts such as sodium and chloride. Nano filters present optimal alternatives to softeners as their ultra-fine filtration capabilities remove salt, eliminate pesticides, and reduce color.
