Recycling Process
ENVIROWIPES, SORBENTS, AND FILTERS
CLEANING PROCESSES: | ||
|
The
soiled wiping rags and sorbents are first loaded into a stream-injected
centrifuge. As steam converts the oils and greases into a liquid form,
the high speed rotation of the centrifuge forces the oils, etc. out of
the material. The fluids then drain into a holding tank for collection.
At this point, approximately 90% of the oils and greases have been
removed preparing the wiping rags and sorbents for laundering and
disposal. | ||

WASTE WATER: |
Wash water discharged from the laundering machines enters a shaker screen and then forwards to a hydro-cyclone separator. This process effectively removes suspended solids even in the low micron range. The water then flows into the mixing tanks where chemicals are added to effectively breakdown the emulisfied oils and greases. From the mixing tanks, the water is pumped to the clarifier where added polymers and micro air bubbles force the sludge to the surface. Skimmer boards skim off the floating sludge into a sludge holding tank. The clean water below the sludge blanket can be discharged or reused. Processed materials not suitable for reuse are collected by Capital Environmental for disposal at Clean Harbors Environmental in Ryley, Alberta. | |
