Select BMPS for TCE degreasing

 

Equipment & Process Modifications

  • Install impervious covers on cleaning tanks to prevent vapor loss
  • Install a vapor level control device for automatic sump shut-off
  • Use super-heated vapor degreasers to facilitate drying and minimize solvent drag-out
  • Use dry pumps on vacuum equipment to eliminate use of oil
  • Use counter-current cleaning methods where possible
  • Preclean parts by wiping instead of rinsing
  • Centralize and consolidate cold cleaning operations to minimize vapor losses
  • Increase drain times for parts before & after washing - to reduce dragout
  • Extend solvent life by avoiding unnecessary solvent additions
  • Extend life of cleaners through filtration
  • Use in-line solvent recovery on vapor degreasing
 

Loss Prevention and Housekeeping

  • Implement and practice preventive maintenance
 

Solid and Hazardous Waste

  • Maximize recoverable waste recycling
  • Research less toxic alternatives for cleaners, solvents, etc.
  • Install solvent recovery system.
  • Frequently inventory & reduce use of low shelf-life material
  • Use material exchanges to finding companies that may use relatively clean streams as a feedstock.
