Interior Grease Interceptors

Note there is 3 lines for the entry of sink compartments.  Sink 1 is filled in above.  In the column headed No., the quantity is 1.  If there are 2 equal size compartments from 1 sink discharging to the interceptor, you would list 2 in the no. column.  Enter the rest of the line to match that row.  Enter a number and press Tab to move to the next column.  The GPM should be the same after you fill the row and Press Enter or click the Submit the Calculations button.  If there is another sink discharging to the interceptor or another compartment of a different size, use the Sink 2 row to enter the measurements.

Woks are entered in the same manor, but the formula is not the same to figure the GPM.  Use the mouse pointer to move to another section.

Directly under the Wok section are text boxes to enter a special fixture and the anticipated flow rate.  Just Below that the total GPM from sinks, woks and special fixtures is listed.

Dishwashers are added by entering the number of racks per hour and the gallons per rack.  The result is the amount of liquid holding in gallons required by the interceptor and not the GPM flow.  The GPM from sinks, woks and special fixtures are added to the liquid holding required from the dishwasher and the total then becomes the minimum liquid holding capacity in gallons required by the interceptor.

Choosing a disposal works in the same manor as a dishwasher with the exception that if the holding capacity required by the dishwasher and sinks already exceeds the holding capacity required by the disposal, no additional capacity is required.  But if the liquid holding capacity required by the disposal is greater than the total from the dishwasher and the sinks, the holding capacity required by the disposal becomes the required total.

Play with some of the numbers and option buttons and see the result. Remember to press Enter or click the Submit the Calculations button.

Exterior Grease Interceptors

Now experiment with the 2 Exterior Grease Interceptor Calculators.  Enter the information just as shown in the screen shot on page 2.  Change from municipal sewer to POWTS and also Paper Service Yes and No. Remember to press Enter or click Submit the Calculations.  Notice the effect to the capacity required.

You should now be starting to be comfortable with using the Internet Calculators.  Before logging in to complete the course, read the instructions below as they contain information that will be required in the 45-question quiz.

There are 21 questions relating to the code paragraphs in subsection Comm 82.34(5).  You can either familiarize yourself with it or have the code handy when taking the quiz.  19 questions relate to using the Internet Grease Interceptor Calculators and the result of the calculations.  5 questions are on the piping in the drawing.

The first calculation you will be required to do is for a commercial kitchen with an interior grease interceptor specified.  There is a partial drawing on the next page showing a plan view of the kitchen.  The sink sizes are listed and will be used for the calculations.  The wash and rinse compartments of the scullery sink and the prep-sink will be included in the calculations.  Add 2 Woks each with an 18-inch diameter and a depth of 6-inches.

The dishwasher has 54 Racks/Hr and uses 2 Gal/Rack.  After filling in the information to that point, press Enter or click Submit the Calculations and then print the calculations from your brouser, mark it page 1 and save the page for the Internet quiz.

Next click the button for a 2HP disposal and press Enter.  Print the page again and mark it page 2.

Next will be a restaurant with an exterior grease interceptor specified.  The restaurant will be serving meals 16 hours per day, does not have any CSS, does have 1 DUW and 75 seats, no dishwasher and no disposal.  First print the result with municipal sewer.  Then change to a POWTS system, press Enter and print  Add a dishwasher to the calculations with a POWTS system and print.  Change to Both (dishwasher and disposal) and print.  The last calculation is POWTS, Both dishwasher and disposal and all paper service.

The last section of the application is used to calculate an exterior interceptor first for a dinning hall serving meals for 10 hours, 600 total meals, 3 meal periods and discharging to a municipal sewer.  Print the calculations.  Next choose all paper service for the same dinning hall and print again.

The last 2 calculations are for a school serving meals for 2 hours to 500 people, 2 periods and discharging to a municipal sewer.  Print the calculations. Next change to all paper service and print the calculations again.

You will need those calculations when doing the quiz on the Internet.  Doing this will cut down the amount of time required to be on the Internet.

Below is a plan view of the kitchen used in the interior grease interceptor calculations.  Use the sink sizes shown in the drawing for the calculations.
