UNISOL has fully integrated 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.
AMS membrane features:
Includes acid resistant membrane, alkali resistant membrane (base resistant membrane), solvent resistant membrane.
AMS membrane supports nano- filtration and ultra- filtration.
AMS membranes sustain aggressive solutions for up to 3 years.
It with stability to temperature and pressure.
Working temperature up to 80 °C. No need for cooling. Improved permeate flux.
Working pressure up to 70 bar. Can treat viscous streams. Improved permeate flux.
Pressure drop up to 1 bar per module. Can treat viscous streams. Higher flexibility in system configuration.
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 Membranes Products
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.
