Acid/alkali/solvent membranes aim at industrial use

Speciality ultrafiltration and nanofiltration membranes were shown for the first time at last week's Aquatech exhibition in Amsterdam, Netherlands, by Israeli company AMS Technologies.

The company, which was founded in 2012, believes that its complete line of extreme acidic, alkaline and solvent membranes will find applications in the mining, chemicals and pharmaceuticals, pulp and rayon, and paints and coatings industries.

ABS claims superior chemical stability for its membranes, UltraPro™ and NanoPro™. Tested acid solutions include 20% H2SO4 , 20% HCl and H3PO4, while tested alkali solutions include 20% caustic soda and 20% potassium hydroxide.

Tested solvent solutions include: methanol, propanol, ethanol, acetone, hexane, THF, NMP, DMF, methylene chloride and alcohols. The membranes have thermal durability up to 80°C and pressure durability up to 70 bar.

Reference cases cited by ABS include:

· Concentrate ions in mining production process - increase extraction rate and yield by up to 5%
· Clean and recover valuable industrial acid/base/solvent streams - save up to 80% on acid/base and neutralizing agent cost and recover valuable materials.
· Treat aggressive industrial waste streams efficiently - cost-effective compliance with instensifying environmental regulations.
