Building a “Green” WorldTakes Everyone Working as a Team

…and seems to be the focus of every city

Park Environmental Equipment

Household wastes drain directly into

Sanitary Sewer with no additional

treatment.

Public Awareness is the onlySolution!

But,

Commercial Buildings

Must collect and treat fats, oils, grease (FOG) solids and chemicals before they leave the

owner’s property.

Why do all major cities have a “FOG” program?

Who is paying for the program?

Planning for Decontamination Wastewater

From Homeland Security – Post 9/11Plan to Design for:

•Chemical Warfare Agents•Biological Disease•Radioactive Materials•Compounds used in the decontaminations process

Where does this Wastewater Drain?

Decontamination shall be performed in geographical areas that will minimize the exposure of uncontaminated employees or equipment to contaminated employees or equipment.

Includes all operations involving hazardous waste that are conducted at treatment, storage, disposal (TSD)

Basics of All Sanitary Sewer Interceptor Design

We know for commercial design:

It shall be UNLAWFUL for any industrial user to discharge into the public sewer:

Two Most Important!

1. Free or emulsified oil & grease over an average of 100-400 (mg/l)

2. Acids or Alkalis which attack or corrode sewers or sewage disposal structures or have a pH value lower than 5.0 or higher than 11.0

Acid Neutralizing Devices

So, what’s the confusion?

1. Grease Trap2. Mechanical Trap3. Grease Interceptors4. Automatic Grease Removal Device (GRDs)5. Gravity Grease Interceptors6. Hydromechanical Grease Interceptors7. New! FOG Interceptors

A Confusing Mess!

Confusion over Names of Grease Traps

Grease Interceptors Names IPC & UPC since 2000

IPC 2006 and 20091. Grease Interceptors

2012 IPC finally changes these to “Hydromechanical”

2. Automatic Grease Removal Device(there is no name for the most popular “outdoor” Grease Interceptor)

UPC 2006 and 2009

1. Hydromechanical Grease Interceptors2. Gravity Grease Interceptors

IPC 20151. FOG (Fats, Oils, and Greases) System

The confusion is IPC can’t settle on name for grease interceptors IPC/UPC 2000 & 2003 called them Grease Traps tested to PDI-101

What happen to the ole Concrete Grease Trap by

???

“They picked everyone but us?”

IPC 2006 & 2009

Cities have to amend the Codes

The “Fallout” when this happens…

Hydromechanical IPC-Grease Interceptors

The mechanical grease trap is often installed in a kitchen area by the sink (but should be designed away from any food handling)

Key! Flow control devices (orifices)

Serviced by the kitchen employees rather than professionals

Manufactures recommend daily cleaning due to the small size

Two Types of Backflow

2. Back Siphonage - Loss of pressure below Atmospheric Pressure (water hose left in soapy water bucket)3. Back Pressure – any elevation of pressure in the downstream piping (by pump, elevation of piping, or stream and/or air pressures

Two Types: Atmospheric & Pressure Type (testable)

Used on on Non-Potable Water Applications Where it is Not Subject to Backpressure

Backflow Preventer Types

Double Check Backflow Preventer Used on closed loop systems

typically on fire service lines

Where no other access to water for pubic use may be accessed (valves, hose closets, etc)

Backflow Preventer Types

Detector Check Backflow Preventer Similar to the Double
