HYDROSTOP offers an innovative method for the aggregate recycling phase of concrete production, using a solid/liquid separation process for fresh concrete.
This method is based on the use of an advanced hydrodynamic treatment system, designed to efficiently separate the solid and liquid components of fresh concrete. The process begins with the introduction of fresh concrete into a treatment unit specially designed by HYDROSTOP or offered by its partners.
Once in the treatment unit, the fresh concrete is subjected to a controlled flow of water and precise hydrodynamic forces. These forces act to separate the solid aggregates from other concrete components, such as water and fines.
The solid aggregates recovered in this way can then be recycled and reused in the production of new concrete, reducing dependence on virgin materials and contributing to the sustainability of the concrete industry.
At the same time, the solid/liquid separation process also recovers the water and fines present in fresh concrete. This water can be filtered and reused in the production process, reducing overall water consumption and liquid waste generated by the concrete industry.
In summary, HYDROSTOP’s method of solid/liquid separation of fresh concrete represents a significant advance in the recycling of aggregates in concrete production. It enables more efficient use of resources, while reducing the concrete industry’s environmental footprint.
Sand/gravel separation screw
Objectives:
The reclaim screw recovers water from truck mixers and/or various cleaning operations (mixer wash water, bucket wash water, mold wash water, etc.).
Extracted sand and gravel are clean, slightly moist and reusable. They present a solid fraction, clean and valuable, while reducing the tonnage of waste.
This fraction consists of a solid part (sand/gravel) and a liquid part made up of water and laitance (charged water).
There are different types of screw, each adapted to the different configurations of your production units.
