Summary
Product identification
The AK Series are Low Energy Brackish Water RO Elements from the A-Series family of proprietary thin-film reverse osmosis elements, characterized by high flux and high sodium chloride rejection. These elements allow significant energy savings, achieving good rejection at operating pressures as low as 100 psi (689 kPa).
- Membrane: A-series, thin-film membrane (TFM)
