Eliminating Odor Complaints, Minimizing Pumping, Seeding Downstream Lines with Aerobic Microorganisms

A Caribbean resort struggled with severe odors and frequent pump-outs from its three-chamber grease interceptors.

After installing IMET Grease Modules in each chamber, odor was reduced to negligible levels and grease accumulation dropped so dramatically that pumping was reduced to occasional surface skimming.

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

At Chewonki (an internationally recognized environmental education nonprofit in Wiscasset, Maine), heavy grease loading from kitchen operations was overwhelming the site’s grease interceptor and septic system, creating thick bio-solids buildup and frequent pumping needs.

IMET installed two aerobic biological modules directly in the grease interceptor, rapidly breaking down fats, oils, and grease while seeding the downstream septic system with beneficial aerobic microbes. Within two days the heavy FOG layer disappeared, and since installation in 2021 the interceptor has sustained no FOG build up and required no pumping, while septic tank pumping frequency has been reduced by 50%.

Using IMET® Technology to Minimize Odor and Bio-Solids Buildup at an Ottawa County Pump Station

After installing an IMET system at Pump Station 50 (PS 50) in a prominent neighborhood in Ottawa County, Ohio, hydrogen sulfide (H2S) odor was significantly reduced to negligible levels. This is a major win considering the proximity of the pump station to residential homes and Catawba Island’s high tourist population in the summer. The organic mat that formed on top of the wet well disappeared, helping regulate the water levels and reducing how often it needed to be pumped.

The system delivered 80-95% reduction of CBOD5 in the wet well depending on the fluctuating residence time due to Catawba’s seasonal population changes.

Ottawa County reduced the amount of calcium nitrate sent upstream by 2,470 gallons, resulting in $6,700 in chemical savings from February to September of 2025.

IMET® Grease Modules at Ciragan Palace Kempinski, Istanbul Turkey

IMET Corporation installed one of the world’s first commercially successful Fats, Oils and Grease or (F.O.G.) “drop in” wastewater treatment technologies at the world famous Ciragan Palace Kempinski Luxury Hotel in Istanbul, Turkey. IMET Grease Modules (IGMs) provided a completely green solution to the significant odor issues and line plugging issues associated with onsite grease traps and lift stations at the hotel while providing the hotel with the opportunity to re-use its “grey water”.
