Acid Sorption

Description

  • Pass the contaminated acidic solution through a resin medium, and the resin sorbs the acid
  • Treat the remaining solution by metal recovery or disposed of if as a waste
  • Pass clean water through the resin, to recover the acids, and reuse as the process chemicals
  • Can be used on a continuous basis
  • Applicable for low to medium acid concentration solutions

Advantages

  • Metal contaminants are removed from the solution
  • 30 - 65% of acid is recovered
  • Improves bath composition quality

Implementation Process

  • Determine which acid baths are dumped most frequently
  • Identify necessary equipment
  • Perform a cost analysis of the system
  • Implement
