What EM•1® Waste Treatment Is
EM•1® Waste Treatment is a liquid multi-species culture of naturally occurring microorganisms — lactic acid bacteria, yeasts, and photosynthetic bacteria — co-fermented into a stable community. Read more about what EM Technology® is and how it works.
Where It's Used
Operators incorporate EM•1® Waste Treatment into a range of wastewater and effluent systems, as part of their broader management program:
Industrial effluent systems
Food processing, dairy, and other industrial operations managing effluent.
Treatment lagoons
Aerated and non-aerated lagoons across agricultural and municipal operations.
Municipal sewage systems
Incorporated into wastewater-management programs alongside existing municipal infrastructure.

Regulatory Compliance
Compliance is your facility's responsibility
If your facility operates under a discharge permit, watershed protection requirement, or other environmental compliance program, meeting and maintaining those requirements is your responsibility as the permit holder. EM•1® Waste Treatment is not a substitute for required engineering controls, monitoring, or permit compliance, and we make no claim that it ensures or supports compliance with any specific regulatory standard. Work with your environmental compliance team, engineer, or regulatory agency to determine what your system requires.
