Model EF-271 - Odor Control & Biological Digester



Earth First's specially formulated blend of natural digesters and odor control compounds provide quick and effective H2S control via bio-remediation. By attacking and killing sulfur producing bacterias found in raw sewage, septic/holding tanks, digesters and holding ponds, our product rapidly breaks down carbohydrates, proteins, fats, sugars and other complex organics. The microbes in our EF-271 product efficiently metabolize the organic materials resulting in reduced BOD (biological oxygen demand) and improved stability of the biological system.
