Beton Lana

Plant for water clarification and sludge treatment from aggregate washing
Main requirements:

  • Enhancement of the pre-existing clarifier, used as a storage tank and integrated in the new plant
  • Use of the existing filter press with modifications carried out on site for reaching ultimate performance.
  • Integration of a new clarifier and filter press to the existing system, keeping the footprint reduced.
  • Highest reliability and reduction of plant downtime to minimum
  • Fully automatic operation
  • High volume of treated material and need to purify more than 400m3/h of water in closed cycle.

Plant details

Exploitation of the existing clarifier

With appropriate metalwork modifications, the clarifier was used as a storage tank for clean water and integrated into the new plant.

Modernization of the filter press

Since it was not possible to carry out the changes at our company premises, the implementations were carried out on site, such as the integration of the filter water recovery basin, which was added under the support legs, as well as software implementations.

Filer press redundancy

A new generation filter press was added to the existing one, equipped with an integrated, automated washing system.

Fully automated operation

The SADF, the automatic flocculant dosing system, verifies water parameters in real time and intervenes on flocculant dosing; in addition, an internal clarifier probe (LEM) monitors sludge levels, avoiding empty cycles in the filter press.
