Eliminate Lint in
Cleaning Facilities
Install lint
traps and filters on drains from equipment and work areas, or
rough-in plumbing for these in potential professional cleaning
tenancies: dry cleaners, Laundromats and carpet cleaners.
All commercial
laundry facilities, Laundromats, and dry cleaners with laundry
facilities are required to install a lint trap or settling pits
for discharge from washing machines. They are prohibited to discharge
wastewater with a temperature greater than 104° Fahrenheit.
The pH of wastewater discharged must be no greater than 11.0 or
less than 5.5.
Dry-cleaning
facilities are strictly prohibited from discharging wastewater
from their dry cleaning operations. Separator water cannot be
discharged to the sewer system or added to the boiler. Separator
water can be treated onsite by filtration/ evaporation methods,
or untreated waste-water can be hauled offsite by licensed disposal
companies for treatment. To treat separator water on site, approved
equipment is available commercially; for information, the Industrial
Waste Section should be contacted at (310) 458-8235.
Cautions
- Lint traps
or settling pits should be periodically maintained and serviced.
Receipts indicating when lint traps or settling pits were last
serviced should be kept on file.
- Equipment
to treat separator water should be maintained and serviced periodically.
