AGITATORS AND MIXERS FOR BIOGAS PLANTS

Proper mixing is a critical factor in the performance and stability of any biodigester. Agitators ensure homogeneous distribution of substrates, prevent sedimentation and floating layers, and maintain consistent contact between microorganisms and organic matter.

Effective mixing improves gas yield, enhances process stability, and reduces the risk of dead zones or crust formation. It also supports uniform temperature distribution and prevents local overloads that could disturb biological activity.

In short, a well-designed mixing system increases biogas production, protects the digestion process, and extends the operational life of the plant.

Efficient mixing is one of the key factors for stable and high-performance biodigester operation. Proper agitation prevents sedimentation, avoids floating layers, ensures uniform temperature distribution, and maximizes biogas production.

At Aqualimpia Engineering, we supply high-quality agitators and mixers specifically designed for demanding anaerobic digestion environments.

Our mixing systems are manufactured in Germany according to strict industrial standards and are engineered for continuous operation under harsh biogas conditions.

We use:

• Corrosion-resistant materials

• Stainless steel components (AISI 304 / 316 / 316L)

• High-grade mechanical seals

• Industrial-duty gearboxes and motors

All components are selected to withstand aggressive substances such as H₂S, ammonia, and moisture.

Biogas environments are classified as potentially explosive atmospheres. Our agitators are available in ATEX-compliant versions, ensuring safe operation in hazardous zones.

This guarantees:

• Explosion protection

• Compliance with European safety directives

• Reliable operation in gas-tight installations

• Safety is engineered into every component.

 Our agitators and mixers provide:

• Optimal substrate homogenization

• Prevention of sediment build-up

• Elimination of crust formation

• Improved heat distribution

• Enhanced methane yield

• Reduced dead zones

We offer different configurations depending on reactor type:

• Submersible mixers

• Side-entry agitators

• Vertical mixers

• Top-mounted agitators

Each unit is dimensioned according to tank geometry, substrate characteristics, and process requirements.
