Reuse rinse water in process tank

Description

  • Reuse the rinse water by transferring it in the heated process tank
  • Never use rinse water from a cleaning process, such as an acid or alkaline etch, to make up the process bath because the rinse water will contaminate the bath

Advantages

  • Decrease the amount of disposed rinse water
  • Decrease the use of freshwater for process bath
  • Retain chemicals necessary for the process

Implementation Process

  • Reconfigure the pipes to provide this flow
  • Determine the optimum temperature range for the bath
    • Heat the tank at the upper end of the optimal operation range. Heating lowers the liquid’s viscosity, allowing for it to drip off more easily.
    • Monitor the temperature
  • Develop an updated ‘Standard Operating Procedure’
  • Train and monitor employees – give incentives for superior performance
