Bioaugmentation can be used in a variety of food processing wastewater treatment applications: fats, oils and grease removal; odor control; as well as for example, biogas production.
Biogas production during food processing wastewater treatment
Industrial plants with high organic loads are more frequently turning to anaerobic treatment. Not only do the plants require less energy and generate less sludge, they are also a prime source for biogas generation. With expanding corporate sustainability targets and a rising demand for renewable fuels and bioenergy, numerous industries are looking for solutions to capitalize on anaerobic treatment and generate even more biogas.
Fats, oils and grease removal during food processing wastewater treatment
Fats, oils and grease (FOG) are one of the main causes of many food processing wastewater treatment issues. When FOG gets into the wastewater treatment system, it can foul sensors, cause foaming and encourage the growth of filamentous organisms. If FOG is not properly degraded in the aeration system, it can cause permit violations. Physical removal through skimming is expensive and labor intensive. FOG is biodegradable, but in many systems the microbial community does not maintain enough of the right microorganisms to keep FOG levels under control.
Odor control during food processing wastewater treatment
Objectionable odors continue to rise on the list of major process considerations in industrial and municipal wastewater treatment and collection. While several products and strategies exist for odor control, bioaugmentation has the unique ability of being able to respond in a dynamic manner. As microorganisms degrade odor-causing compounds, odors simply disappear. Novozymes offers several strategies for controlling odors during food processing wastewater treatment
