N2 - An experimental investigation is presented of the thin‐channel ultrafiltration of 0.6 × 10−3 M to 15.0 × 10−3 M aqueous solutions of Cu2+, Ni2+, or Zn2+ sulfate or chloride salts through a negatively‐charged, non‐cellulosic membrane. Multi‐salt solutions and the actual rinse water from a Watts‐type‐nickel‐plating process are also ultrafiltered. The membrane provides a Ni2+ rejection of 0.83 and water flux of 1.0 × 103 cm/sec (23 gal/ft2 day) at a transmembrane pressure difference of 4.0 × 105 N/m2 (3.9 atm). The membrane rejection and water flux data are utilized in a computer simulation procedure for scale‐up to a multi‐module, two‐staged process for the closed‐loop operation of a plating plant.
