Description

The AL Series of thin-film reverse osmosis (RO) membranes are characterized by high water permeability and sodium chloride removal. The AL Series RO membranes are selected when low operating pressures are desired while maintaining a relatively high removal of organic substances, nitrates, micropollutants, and water hardness.

The AL Series membranes are designed specifically to operate in applications where low energy consumption is of high importance, as in municipal drinking water, beverage, light commercial, residential, and general industrial.

The AL Series membranes have been certified for potable water treatment and have the following certifications:

• ACS (Attestation de conformité sanitaire)
• NSF/ANSI/CAN 61
