The first step, primary or mechanical treatment, removes large, suspended and floating solids from raw sewage. The next step is called secondary or biological treatment. Biological wastewater treatment confines high concentrations of naturally occurring bacteria in treatment tanks. These bacteria, along with protozoa and other microbes, form activated sludge. When the activated sludge bacteria “eat” small organic carbon molecules, the wastewater is cleansed.
Biological treatment is widely used because it is more cost effective than other types of treatment processes, such as chemical oxidation or thermal oxidation. An increasing demand has been placed on food processing plants and municipal wastewater treatment facilities to process higher levels of waste. This pressure has led to the release of improperly treated effluent into our rivers, streams and lakes.
To help these plants meet legal and environmental discharge limits, we have created our series of microbial blends designed for use in wastewater treatment systems including municipal sewage plants, food processing wastewater, pulp and paper mills, and livestock manure lagoons.
