Biogas can be processed and used as a utility or even sold and fed back into the power grid.
Dependable online, inline, and atline solutions for your waste processing needs.
Wastewater must be treated so it can be released back into the environment without adverse effects on an ecosystem. Especially in the food and agricultural sectors, carbohydrates and many other organic compounds are introduced from washing procedures and other processing steps. Discharging this nutrient-rich effluent without sufficient treatment would lead to prolific bacterial growth, deoxygenating the water and killing aquatic life.
Formation of biogas from waste products
Biogas is created when organic substances are decomposed in a four-step anaerobic digestion process (hydrolysis, acidogenesis, acetogenesis and methanogenesis). Before it is refined, flammable biogas is a water-saturated gas mixture that consists largely of methane (CH4) and carbon dioxide (CO2). The CH4 component is most important in the use of biogas, since the oxidizable compound releases energy when burned.
Benefits of online monitoring
A shutdown, cleanup, and replacement of the bacterial sludge is extremely costly, calculated in the hundreds of thousands of dollars for even a small overloading event. On the other hand, process optimisation can lead to additional income from several areas in the plant, such as the sale of excess sludge or produced heat as a utility. It is therefore extremely important to constantly monitor all processes relevant to the formation of biogas in order to reduce waste and maximize profit in many areas
