Top Tips for Pollution Prevention for Dry Cleaning / Garment Care Shops
- Converting to newer, more efficient equipment (e.g., closed loop dry-to-dry system) reduces solvent use
- Replace an activated carbon adsorber perchloroethylene trap with a refrigerated condenser to reduce the generation
of perc-contaminated separator water.
- Make sure any additives you put in the solvent are completely dissolved before the solvent goes through
- Keep the filter housing full of solvent when you are not using the equipment.
- When you run the still, do not let solvent return temperature go above 90 degrees Fahrenheit (32 degrees
Centigrade). This will minimize solvent loss through the storage tank vent.
- Inspect equipment and piping regularly for leaks, worn parts, proper temperatures, solvent "mileage." Repair
- Do not dispose of separator water down a drain. Ship separator water as a dangerous waste.
- For a refrigerated condenser on the dryer vent: be sure the temperature in the outlet of condenser is
not above 45 degrees Fahrenheit.
- For an activated carbon adsorber on the dryer vent: measure the
perchloroethylene concentration in the outlet from
the adsorber with a colorimetric detector tube or hand-held detector. It must be less than 100 parts per
If it is higher, regenerate or replace the adsorber. The activated carbon is a dangerous waste when
