IVM - Vault Toilets

IMET® Vault Module

Eliminates H2S Odor to Negligible Levels
Minimizes Biosolids Pumping

The aerated biological IMET® Vault Module (IVM) creates a near 100% aerobic environment in the vault toilet. IVM systems eliminate odors to negligible levels and continually consume dissolved bio-solids in the tank,  significantly reducing the pumping requirement of bio-solids from vault toilet.

IVM systems use minimal energy and can be directly connected to an on-site electrical source or can be connected to solar power for applications that are off grid. ​IMET® IVM systems do not use any chemicals.

Key Benefits:

  • Reduction of H2S odors to negligible levels

  • Sustained biological treatment of bio-solids

  • Minimize pump truck pumping of bio-solids

  • Deployable both on and off grid

  • Easy to install

  • Minimal maintenance

  • Adaptable to any size tank

  • Retrofit to existing system

  • Green Infrastructure

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 vault toilet 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.

IVM System:

  • IVM standard size, with custom sizing available

  • 200-250 watt air pump

  • Stainless steel housing (if necessary)

  • Solar options available

The continued success of the IVM is further proof that Nature’s Way Works.
