ASME A112.14.3:2000:2021 pdf download.GREASE INTERCEPTORS.

These motions shall be so regulated as to have the baffle submerged to within I in. (25 mm) of its top by the time it reaches the end of the last 2 in. (50 mm) of horizontal travel. The bafle shall then be removed from the water

and moved, grease side up, to the pail where the adhering grease shall be squegeed of and added to the previous

contents.

By now, the first baffle has cooled, and the above procedure is repeated using it. The baffles shall be used

alternately until the amounts of grease collected in this manner are less than 1% by visual observation.

Upon completion of the above skimming procedures.

the water shall be drained from the botom of the pail by means of the spigot. The pail shall then be placed over a gas flame and its contents heated untill the residual water is brought to boiling temperature; that is, until

bubbles of steam rise through the molten grease. The mixture shall then be poured from the pail into a separatory funnel, the pail shall be squeegeed out and the mixture shall be allowed to stand in the funnel for approximately 5 min, at the end of which time the water is drawn off from the bottom of the funnel. The remaining liquid shall

be permitted to separate for approximately 5 min more and the walter shall again be removed from the bottom of the funnel.

The remainder shall be drained from the separatory funnel into one or more preweighed cans.

The cans shall be cooled to solidify the grease. The cans may be placed in a freezer or refrigerator to expedite

the cooling process. The solidified contents shall then be scraped and kneaded with a small putty knife, and the

water thus worked from the mixture shall be poured off. If the quantity of water thus removed is greater than several drops, the heating and solidification process shall be repeated.
