IMET® Grease Module (IGM) creates a near 100% aerobic environment in the grease interceptor. Bad odors (H2S) are eliminated to negligible levels as anaerobes become dormant.  The aerobic Fats Oil and Grease (FOG) microbes in the IMETs chop up the carbon chains of the FOG molecules, denaturing them.  The chopped-up FOG molecules become easily consumable BOD.

As the aerobic microbes in the ​​IMETs® consume the dissolved grease in the waterbody, the thick floating grease layers begin to lessen as more grease from the surface dissolves into the waterbody and is consumed by the aerobic microbes in the second or third chamber. Pumping is minimized or eliminated in the grease interceptor with minimal skimming required in the first chamber.  The significant population of aerobes grown on the large surface area in the IMETs®  continually seed downstream lines, cleaning the existing pipes of FOG buildup.   

Key Benefits:

  • Nearly 100% aerobic system

  • Minimize or eliminate jetting and pump truck pumping

  • Odors eliminated to negligible levels

  • Accelerates the biological degradation of FOG in water body

  • Continuous inoculation of adapted aerobic microorganisms into downstream sewer lines

  • Eliminate build-up of FOG in down-stream lines

  • Seeds aerobic microorganisms to WWTP 

​The IMET® technology is a modular design that is able to fit any new or existing system. IMET Corporation offers customers a solution to meet individual client requirements. The IMET® “drop in” technology is designed to create a nearly 100% aerobic environment in a grease interceptor that allows for fast, lasting results.

​The IMET® technology provides superior surface area that allows large, diverse populations of micro-organisms to grow and remain in the IMET® module. Coupled with superior aeration, and a design that utilizes aeration efficiently, the IMET® technology requires less air to achieve maximum results.

Specifications:

  • 1036, 1440 standard size (custom sizing available for non-standard installations)

  • 80-450 watt air pump

  • Stainless steel housing (if necessary)​

Commercial Case Study:

IMET Pre-Treats Camp Grease Interceptor and Seeds Downstream Septic System with Aerobic Microorganisms

Problem: Chewonki, an Internationally recognized environmental education non-profit focused on nature-based education and stewardship in Wiscasset, Maine wanted to reduce or eliminate pumping frequency of its grease interceptor and the downstream septic system while also lessening loading to its leach fields.  The grease interceptor was sending significant Fats, Oils and Grease (FOG) to the septic system creating a very thick and hard build-up of bio-solids when mixed with the black and grey water, resulting in a thick bio-solids mat that was hard to pump out.

A man working on installation or maintenance of underground utility pipes in a backyard or park with trees and two red sheds in the background.

Solution: IMET® installed 2 aerobic biological modules directly into the grease interceptor to pre-treat the grease interceptor waterbody before discharging to the three-tank septic system.  The IMET modules installed also began to seed the downstream septic system with aerobic microorganisms. 

Result: Within two days of installation, the thick FOG layer in the grease interceptor was gone, with only translucent milky water remaining.  Since IMET installation in 2021, the grease interceptor has sustained no FOG build up and has not required any pumping. The downstream septic tank, seeded by the IMET system has had its pumping requirement reduced by 50%.   The camp is very happy with the results and is planning to install 6 IMET modules in the three tank septic system to provide complete treatment before effluent water is discharged to the leach field.
