    1. 1. Presentation By: Jorean Washington, R.E.H.S. Environmental Compliance Section Utilities Water Reclamation Division
    2. 2. Environmental Compliance Providing Controls To Protect Our Wastewater Systems & Environment From Potentially Harmful Discharges F ats O ils G reases
    3. 3. FOG Grease..What is it ?? <ul><li>The word grease is synonymous with Fats, Oils & Greases, or (FOG) </li></ul><ul><li>FOG are compounds of one, two or three faty acids, which combine with a glycerol “backbone”. </li></ul><ul><li>FOG is derived from the living cells of animals and vegetable matter. </li></ul><ul><li>FOG originates from many processes that are performed in industry & food processing. </li></ul>
    4. 4. Basic Grease Molecule
    5. 5. FATTY ACIDS <ul><li>saturated fatty acids (palmitic, stearic) are generally found in high concentrations in solid fats (butter, lard, beef tallow). </li></ul><ul><li>Unsaturated fatty acids have lower boiling points and are generally found in high concentrations in oils (olive, corn, peanut). </li></ul><ul><li>Hydrogenation (add hydrogen) of an oil produces a fat (hydrogenated oil). </li></ul>
    6. 6. Good FOG Management <ul><li>Reduce spills & clogs by eliminating grease at the source </li></ul><ul><li>Protects the wastewater system </li></ul><ul><li>Reduce system Operation & maintenance costs </li></ul><ul><li>Support & achieves Regulatory compliance </li></ul><ul><li>Reduce property & environmental damage and clean-up costs </li></ul><ul><li>Helps to protect public health </li></ul>
    7. 7. Oil and Grease (O&G) Prevention Program <ul><li>Grease Clogs Sewers & Pipes </li></ul><ul><li>Causes 40-50% of all sewer overflows </li></ul><ul><li>Causes most commercial kitchen overflows & backups for facilities utilizing onsite wastewater treatment (septics) </li></ul><ul><li>interferes with wastewater treatment </li></ul>
    8. 8. Pipe blockage
    9. 9. Pipes clogged with various combinations - grease, septage, and roots
    10. 10. Overflows Grease clogged gutter Overflowing from manhole cover caused by grease blockage
    11. 11. Clogged Line breakage spilling oils and grease onto the ground.
    12. 12. Grease & Oil in water on ground
    13. 13. Overflow residuals affecting ground surface areas
    14. 14. After Remediation (clean-up)
    15. 15. Objective of a Fog Program <ul><li>Decrease the amount of Fats oils or greases being introduced into any type of waste water system. </li></ul><ul><li>Resulting in decrease maintenance costs. </li></ul><ul><li>Reduction in pumping frequency </li></ul><ul><li>Improved treatment efficiency </li></ul>
    16. 16. <ul><li>Oil & Grease Prevention Program </li></ul><ul><li>Environmental Surcharge Program </li></ul><ul><li>Industrial Pretreatment Program </li></ul>Program Sections
    17. 17. Facilities that generate FOG
    18. 18. Restaurants - Malls, Stand Alone, Hotels…
    19. 19. Strip Centers, Car Washes, Mechanic Shops…
    20. 20. Interceptors / Traps
    21. 21. Interceptors / Traps S et Up Or Septic System
    22. 22. Sizing for Efficiency <ul><li>Min. Grease Trap Sizing - </li></ul><ul><li>Combined Sink & Fixture Volume (units in gallons) x 0.75 </li></ul><ul><li>1.0 minute (decant time) </li></ul><ul><li>Min. Grease interceptor sizing – </li></ul><ul><li>Shall be min 750 gallons and the maximum volume grease interceptor shall be 1250 gallons. When the required effective capacity of the grease interceptor is greater than 1250 gallons, installation grease interceptors in series is required. </li></ul>
    23. 23. Restaurants <ul><li>(S) X (GS) X (HR/12) X (LF) = effective capacity of grease interceptor in gallons. </li></ul><ul><li>S = number of seats in the dining area. </li></ul><ul><li>GS = gallons of wastewater per seat; use 25 gallons for ordinary restaurant, use 10 gallons for single service article restaurants. </li></ul><ul><li>HR = number of hours establishment is open. </li></ul><ul><li>LF = loading factor: use 2.0 interstate highways, 1.5 other freeways, 1.25 recreational areas, 1.0 main highways, and 0.75 other roads. </li></ul><ul><li>2. Other type establishments with commercial kitchens: (M) X (GM) X (LF) = effective capacity of grease interceptor in gallons. </li></ul><ul><li>M = meals prepared per day. </li></ul><ul><li>GM = gallons of wastewater per meal: use 5 gallons. </li></ul><ul><li>LF = loading factor: use 1.00 with dishwashing and 0.75 without dishwashing. </li></ul>
    24. 24. In Use Grease Interceptors & Traps Under Sink Trap In ground Interceptors
    25. 25. Petroleum Based Oils Oil & Water Separators Used Oil Container
    26. 26. Grease Recycle Containers
    27. 27. Biodiesel <ul><li>Any form of fatty oils from vegetable or animal sources can be converted into useable fuel. These oils contain esters, which are the part that is valuable as fuel, and glycerin, which is a waste product in the fuel production, but a potentially valuable substance when used in the production of soaps, lotions, skin oils, and more. </li></ul><ul><li>The process of separating these elements from the oil is called transesterification </li></ul>
    28. 28. Trap & Fryer Grease … It’s Recyclable ! 60% 20% 20% Make-Up,Candle’s, Food Grade Lubricants Cattle Feed, Dog & Cat Food Poultry Feed, Pork Feed
    29. 29. Grease Recyclers or Renderers ! Oil and Grease Renderers will collect the material from your grease trap and divert it to useful purposes A rendering company will provide service on a weekly, monthly or on-call basis Rendering companies provide receipts for service which should be kept on file.
