Grease Trap

When grease in large grease-laden wastes mix with cold sewage in the mains, causing the grease to congeal and adhere to the solids. By the time, the sewage has reached the treatment plan, a thorough mixing of grease and solids have occurred. Since bacterial action on grease is slow, it does not decompose readily and is carried through the plant, affecting the operations at many points, depending on the type of treatment. These grease interceptors are used in restaurants and institutional kitchens and all types of food handling and processing areas where waste water contains fats, oil and grease. Adequate top space must be available for removal of cover in case of manual cleaning.

For designing size of Oil / Grease Interceptors, consult PDI-G101 or ASME A112.14.3 OR CAN/CSA-B481 SERIES-07.


     

Flow Control Device:

Flow control fittings as a useful part, is furnished with all ALPINE Grease Interceptors and Separators at an added cost. These devices govern flow rate to the interceptor or separator being used, thereby assuring the maximum retention of the material being intercepted and improves efficiency.

DESCRIPTION

At ALPINE the manufacturing process adheres to Canadian standard CAN/CSA-B481 SERIES-07. Built of all-welded heavy-duty fabricated steel plate for maximum structural strength and durability, high volume,  incorporating a removable cover of heavy-duty steel plate for on-the-floor or partially recessed installation, or non-skid tread plate cover for flush with-floor installation suitable for pedestrian traffic (or reinforced for industrial traffic), internal air relief, visible double trap and flow control fittings (optional). The cover is secured to the body with recessed Stainless steel bolts including an extra heavy leak-proof gasket and removable separating screen for easy cleaning. Standard No hub inlet and outlet. Integrated solid interceptor is optional (for improving efficiency).

CLEANING

THE GREASE INTERCEPTOR

Available in MANUAL and SEMI AUTOMATIC MODELS.

The unit should be checked after the first 4 weeks of operation to note the buildup of oil. Based on the amount of floating Grease in the holding tank, a regular cleaning schedule should be implemented to ensure that the grease and fats waste is emptied. A back up in the interceptor, or a sluggishness in the draining of the fixture indicates that it requires cleaning. A regular inspection of the internal condition of the interceptor will explain how oftenly it requires cleaning.

 

1.    Lift the main cover, remove the grease, fats and solids carefully; Do not flush them down the sewer.

2.    Remove baffles along with sediment bucket and clean them.

3.    Replace all baffles assembly and bucket correctly.

4.    Secure cover tightly.

5.    Clean at regular intervals.

  Grease Interceptor Designing:

To determine the optimum size of converter to be used, account must be taken of the volume of fixtures discharging into the interceptor. Use the table below to calculate total volume by entering the quantity of each fixture, multiply be the volume shown and enter as Total Volume; finally, add up your answer.
