At Protech Continental Group, we work to provide technical solutions to the most demanding challenges in agro-industrial waste treatment. That is why we collaborate with Kronoa Engineered Solutions, a specialist in pumping systems, integrating the Biomix mixing pump into our projects. This is a robust, efficient and versatile progressive cavity pump designed for handling complex substrates in co-digestion applications.
Biomix system: much more than just a mixing pump
Biomix is based on a helical screw pump with an open hopper and forced feed auger, capable of handling various types of solid and semi-solid waste: dehydrated sludge, fruit and vegetable waste, flour, manure, silage, and even bulky plant materials such as melons, watermelons, and pumpkins.
The mixture is made in the body of the equipment itself, combining solid and liquid substrates to obtain a pre-homogenised product, which is pumped directly into the process, promoting stable and controlled feeding of the digester.
A key feature of the Biomix pump is its stone separator, which is integrated into the hopper itself., designed for the removal of heavy particles and foreign objects commonly found in this type of application. This system prevents stones or objects of higher density from entering the process, protecting the equipment and installation and reducing the risk of mechanical damage.
Operational advantages and applications
The Biomix mixing pump offers clear benefits for plant operation and efficiency:
- Protection and reliability: the integrated heavy particle decanter reduces the risk of damage and unplanned downtime.
- Versatility: suitable for treating a wide variety of solid and liquid substrates, providing great flexibility in the facility’s diet.
- Homogeneous mixture: pre-homogenisation in the pump body itself facilitates stable pumping towards the digestion process.
- Reduction in operating costs: less wear and tear and fewer maintenance interventions thanks to its robust design.
- Energy efficiency: low-speed operation, optimising electricity consumption.
The Biomix pump is used in various applications:
- Biogas and co-digestion plants, improving the preparation and transfer of substrates to the digester.
- Treatment plants for pumping complex sludge.
- Agri-food industry, in the management of organic by-products.
- Agricultural and livestock environments, facilitating the management of viscous waste with high solid content.
At Protech Continental Group, we are committed to Biomix.
