Side Agitator for Liquid Digestate in Storage Tanks

Overview

The side agitator for liquid digestate is equipment designed to maintain homogeneous biomass in large reservoirs of biogas plants, preventing the sedimentation of solids and the formation of surface crusts. Focusing on maximum efficiency, the Industrial agitatorLateral/Horizontal guarantees the fluidity necessary to facilitate continuous pumping of the processed organic material.

In biogas plants and treatment plants, the storage of digested sludge requires constant and vigorous agitation. Our agitation solutions for digestate tanks are installed directly in the large reservoirs that the customer already has, providing complete mixing without the need to empty the system. For smaller volumes, up to 10,000 liters, we also supply complete Industrial Process Tanks and Reservoirs, developed and manufactured to achieve maximum performance and durability for your process.

Agimix has been in the industrial agitation and mixing solutions market for 15 years, delivering robust projects for the industry in general. Our equipment offers high performance, combined with ease of installation and maintenance, ensuring operational efficiency and reliability in the biodigestion and effluent treatment process.

Depending on the reservoir geometry and fluid rheology, the project can be complemented by a Vertical Agitator, developed with advanced engineering to maximize process efficiency, reducing the plant's energy consumption and ensuring high operational performance at any production scale.

Side Agitator for Liquid Digestate in Storage Tanks

Benefits and advantages

Sedimentation Prevention

Continuous directional flow prevents solids from accumulating at the bottom, ensuring a homogeneous liquid digestate ready for safe pumping.

Low Energy Consumption

The Industrial agitatorLateral/Horizontal uses propellers with a hydrodynamic profile that reduce electrical energy expenditure during continuous operation.

High Corrosion Resistance

Made from special alloys and stainless steel, the equipment withstands the chemical aggressiveness of the digestate and the corrosive gases present in the environment.

Ease of Maintenance

The intelligent design allows quick interventions in the sealing system without emptying the tank, drastically reducing machine downtime.

Tailor-made Projects

We dimension the power and agitation angle specifically for the volume and density of the fluid in your reservoir.

Frequently asked questions

Direct answers to the most common questions about this equipment and its application.

What is a side shaker for liquid digestate?

The side agitator for liquid digestate is equipment fixed to the wall of reservoirs to homogenize the biomass resulting from biodigestion. It creates a horizontal flow that sweeps the bottom of the tank, preventing solids from settling and keeping the material fluid for the booster pumps.

Why is it necessary to agitate the digestate in the storage tank?

Agitation is necessary to avoid phase separation and the formation of surface crusts or accumulation of sludge at the bottom. Maintaining the homogeneous mixture with an Industrial agitatorLateral/Horizontal ensures that pumping for disposal or agricultural application occurs without blockages in the pipes.

Does Agimix supply the giant tanks to store the digestate?

No, Agimix only supplies the industrial agitation system to be installed in the large concrete or steel reservoirs that the plant already has. For smaller processes, we manufacture Industrial Process Tanks and Reservoirs with a maximum capacity of up to 10,000 liters.

What is the ideal material for a biogas and digestate agitator?

The ideal material is 316L stainless steel or higher alloys, due to the presence of highly corrosive compounds such as hydrogen sulfide gas and ammonia. The correct choice of metal alloy guarantees the longevity of the equipment and the safety of continuous operation.

How is the side agitator maintained with a full tank?

Maintenance is facilitated by a mechanical closing system or block valve integrated into the equipment flange. This mechanism allows the mechanical seal to be changed or the gear motor to be repaired without the need to empty the digestate reservoir.

Can I use a vertical shaker instead of the side one for digestate?

Yes, the use of a Vertical Agitator is possible and very efficient, depending on the dimensions of the tank and the support structure available on the roof. Advanced engineering projects evaluate the geometry of the reservoir to define whether lateral or vertical agitation will deliver the best performance for your plant.

What power is needed to agitate digested sludge tanks?

Power varies from 2 HP to 50 HP, depending on the total volume of the tank, the suspended solids content and the viscosity of the sludge. Our engineers carry out exact sizing to reduce energy consumption and ensure high operational performance.

Does the equipment support continuous operation 24 hours a day?

Yes, Agimix agitators are designed for continuous work in harsh industrial environments. We use highly durable gear motors and robust sealing systems to ensure reliability in the effluent treatment and biogas generation process.
