The IMET Treatment Module (ITM) utilizes a patented process of Aerobic Microbial Digestion of soluble organics for a highly effective and efficient remediation of residential wastewater.  IMET technology utilizes its design and the highly diverse and large population of aerobic micro-organisms within the module(s) to treat the wastewater, significantly reducing BOD, TSS and Total Nitrogen in the water body. Residence time is important in the treatment process as it enables the diverse population of aerobic micro-organisms within the IMET module(s) to remain in contact with the dissolved organic waste.  


The high surface area of the media within each module provides residence to a large population of diverse micro-organisms, which limits the growth of suspended micro-organisms outside the module. Therefore, during times of system shock (introduction of disinfectant etc.), the microbial population does not wash out.  Additionally, during times of famine the modules adjusts to meet the decreased levels of dissolved organic waste available for consumption.

Commercial Application Case Study: 
IMET System Provides Complete Treatment Including High-Strength Waste From RV Park

Problem: A new owner of an RV Park in northeast Ohio was challenged with replacing the existing outdated, failing septic system. The park has a peak load of 258 seasonal campsites, 22 transient RV sites and 24 primitive sites. The high-strength blackwater waste was being serviced through an onsite dump station collection system. The showers, the manager’s home and the office were all being treated through the same system. The owner was also tasked with planning for new, centralized lavatories and showers for the RV park to be connected to the new wastewater treatment system.

Solution: The Potter’s Company designed a wastewater treatment system employing the IMET aerobic packed-bed media biological reactors for complete treatment to discharge into a drip distribution system for soil dispersal. The reactors are first used to treat the high-strength waste from the dump stations. Treated effluent from the dump stations is then mixed with the waste from the manager’s home, office, new lavatories and showers in a flow equalization system to manage peak loading. The reactors are then used to complete the treatment of the wastewater to levels below 30 mg/L for safe soil absorption.

Result: The EPA-permitted wastewater treatment system went into successful operation Feb. 6. The park is open to seasonal campers and fully operational. On a recent visit to the site, dip samples were taken through the treatment train, as seen in the inset images.
