Maximizing anaerobic digestion with pumping & mixing: discover BiogasWorld’s clients and their technologies 

Pumps and agitators are important components of every biogas plant and are available in different versions. Existing variety of pump and mixer technologies ensures the perfect control of the treatment, grinding, transfer and distribution of effluents, in industrial, agricultural or biogas production processes.

Pumps perform the grinding and pumping of the inputs. Thanks to a wide range of materials and equipment, pumps are ideal for pumping all fluids.

Agitators designed for heavily loaded liquids mix the substrates. In anaerobic digestion, the submersible mixer is used in digestate storage. In agriculture, this submerged mixer ensures the homogeneity of thick liquids.

Eisele, the company with over 25 years of experience in biogas industry, explains that “in digesters and final storage, submersible mixers with a gas-tight control system must meet the highest industry requirements. It ensures that the fresh and co-fermented slurry supply is mixed with the existing fermented substrate, that the floating crusts and deposits are broken and/or destroyed, and that the distribution of heat is homogeneous in the digester. The optimial mixing of the substrate ensures high and constant biogas production. ”

MIXRITE, leading manufacturer of Fluid Mixing Systems, states that mixing is one of the most important operations for successful anaerobic digestion plant.”This applies not only to the Digester but also applies to inlet tanks, separation system, blending tanks and post digestion storage. In order to achieve good yield from Digester, it is essential to ensure that a good intimate contact is established between feedstock and microbes, stratification is avoided and, solid build up at bottom is minimized. If all these factors are well within control, Digester will yield maximum gas production and good quality digestate. It is rather difficult to accomplish all these criteria with conventional Rotating Agitator.”

Choosing the right mixing technology

Choosing the right mixing technique is important to achieve the highest possible yield in your anaerobic digester. It is only when the agitators are adapted to the size of the tanks and the specific characteristics of the substrates that the fermenting material forms a homogeneous liquid mixture.

Our clients are world leaders and innovators in pumping and mixing for biogas, agricultural, industrial and wastewater applications. Their pumps and agitators of all sizes and for all kinds of substrates are installed in thousands of plants around the world. Whether for urban and industrial wastewater treatment plants or for agricultural applications (slurry and biogas), our clients will assist you in the selection and installation of mixing and pumping systems.
