AMS Membranes series offers an extensive line of innovative acid-stable, alkali-stable and solvent-stable nanofiltration and ultrafiltration membranes with elements for use in the respective media.
“AMS Membrane” originated from Israel, is a series of acid- and alkali-resistant and solvent-resistant special membranes, which are representative of the former AMS TECHNOLOGIES INT.(2012) LTD. These membranes are capable of stable operation under high temperature and pressure of strong acid, alkali and solvent environments. The main applications are in the mineral extraction industry (mining) and in industries with harsh working environments, such as pharmaceuticals, pulp, rayon, dairy and chemicals. Its core technology can effectively save cost, improve recovery rate, improve the reliability of acid/alkali/solvent supply, bring obvious environmental benefits, and create considerable economic value for various industrial applications.
UNISOL has fully integrated the former Israel AMS membrane's technology and AMS membrane products (www.amsmembrane.com) into its products portfolio.
AMS membranes series offers an extensive line of innovative acid-stable, base(alkali)-stable and solvent-stable nanofiltration and ultrafiltration membranes with elements for use in the respective media. Our state-of-the-art chemically- and thermally-stable NanoPro™ and UltraPro™ membranes are applicable to a wide range of industrial separation applications.
All the products are packaged in a spiral wound configuration of 1.8", 2.5", 4" and 8" diameter with 31 and 46 mil feed spacers and a variety of components suitable for working in harsh environments. Other feed-spacer sizes are available on request.

Application
AMS membranes are used for 10+ years on the market, working in various industries under harsh conditions to recover acids, caustic soda, solvents.
Chemicals: Organic solvent nanofiltration (OSN) and end products concentration (e.g. chloral – alkali plants)
Pharmaceuticals: Solvent recovery and API concentration (e.g. antibiotics and antibiotic intermediates)
Food & Beverages: Caustic soda recovery from Clean-in-Place lines
Paints & Coatings: Solvent and paint recovery from spent production line wash streams
Mining & Metals: Acid recovery from leaching circuits, electrolysis and electrowinning units, galvanization baths
Pulp & Rayon: Caustic and celluloid recovery from pulping liquors
UNISOL AMS Flat Sheet Membranes
AMS line of NF and UF membranes sustain aggressive solutions for up to 3 types. For every aggressive reagent there is a special membrane type.
