Innovation and sustainability with System Products of VTA Austria GmbH

Hercal-Zero (H-Zero), a prominent company specializing in the production of concrete blocks from recycled aggregates, sand, and gravel, has adopted an advanced washing water treatment system. This cutting-edge solution, powered by the innovative Speedfloc 50 from VTA Austria GmbH, enhances sedimentation efficiency and streamlines sludge management.

Key Benefits of Speedfloc 50

The use of this new generation of chemicals, known as SYSTEM PRODUCTS, has delivered excellent results:

 

• Efficient sedimentation without the need for additional polymers in the washing of aggregates and cement, simplifying preparation and dosing operations while reducing costs.
• Reduction in sludge viscosity, facilitating its handling and final disposal.
• Increase in the amount of settled sludge, enhancing the recovery of solids.
• Improved filterability in filter press fabrics, eliminating adhesion issues and ensuring clean sludge cake release, reducing cycle times and increasing daily production.
• Operation under extreme conditions of alkaline pH (pH > 10) and conductivity (up to 4.5 mS/cm), allowing system water renewals to be reduced to once per year, significantly lowering consumption and associated costs in the plant.

Project Impact

The implementation of this solution has transformed the company's water treatment system, achieving:
 

• Greater operational efficiency: Reduced time and costs associated with treatment processes.
• Optimization in aggregate recovery: Increased use of recycled materials thanks to cleaner water for closed-cycle washing.
• Reduction in environmental impact: More sustainable treatment with lower annual water consumption in the plant.

This initiative strengthens H-Zero’s commitment to sustainability and technological innovation, consolidating its position as a leader in responsible environmental management and the development of efficient and economically viable solutions.
