Current RO membranes are inefficient

As water traverses an RO membrane it must do so through the many apertures within the porous structure. In conventional polyamide RO membranes these pores are a chaotic mesh of interconnected passages that twist and turn throughout the membrane. This type of structure provides a lot of resistance to the passage of water molecules across the membrane, and the net result is low permeability membranes that require a high operating pressure.

Anfiro's membrane technology

Our membranes create a nanoscale porous pattern of cylindrical pores that go straight through the membrane selective layer, with minimal pore-to-pore size variability. The result is a massive increase in permeability without sacrificing selectivity performance. Anfiro's self-assembling polymer technology is enabling a new generation of energy-efficient membranes that can significantly reduce the operational and capital costs of an RO system.

Chlorine is one of the most widely used water disinfectants, yet current RO membranes are permanently damaged when exposed to chlorine. Unlike current membrane technology, Anfiro's polymer materials are not degraded by exposure to chlorine. This enables chlorine to be used throughout the RO stage, which reduces bio-fouling and can lead to a longer membrane lifespan.
