Chances are if you are an industry professional, you've tried dozens of products for odors and digestion of solids. Have you tried EM•1® Septic Treatment yet? They are not all the same.

EM•1® contains:

  • Billions of live active colony forming units of microbes per milliliter (CFU/ml).
  • Over 100 active enzymes (including protease and lipase) that break down grease and proteins.
  • Live microbes from four genus

No other product on the market today has the complex makeup of EM•1®. No other product has the global impact of use in over 100 countries in all climates from tundra areas in Alaska to tropical Costa Rica.

Typical imbalances caused by over loading, harsh cleaners/detergents, antibiotic soaps, drain cleaners and a wide variety of other materials that make their way into the household on-site waste disposal system cause dead systems. Odors coming up from vents and seepage in soils are signs of a failing septic system. Treat it now before it backs up.
