WASTE ORIGIN: Aqueous Cleaning
WASTE TYPES: Aqueous Cleaning Solution and Rinse Water

WASTE REDUCTION AND RECYCLING METHODS:

• Use optional methods like abrasives, water, or steam.
• Use less hazardous acid or alkaline compounds.
• Maintain solution quality:
  • Inspect parts before cleaning;
  • Pre-rinse parts (e.g., with last rinse stage of cleaning operation, using demineralized
  • water);
  • Avoid unnecessary loading;
  • Provide continuous heating;
  • Properly make up solution;
  • Remove sludge and soils promptly;
  • Routinely monitor cleaning solution strength and temperature;
  • Maintain equipment (e.g., racks free from cracks, rust);
  • Reduce drag-out.
• Increase degree of rinsing efficiency while reducing water use:
  • Use de-mineralized water;
  • Use counterflow rinsing;
  • Use spray rinsing;
  • Install fog nozzles.
• Dry parts properly (e.g., automated drying ovens).
