### El decantador más compacto del mercado

ACTIFLO™ utiliza microarena (Actisand™) como precursor para la formación de flóculos pesados más fácilmente decantables que permiten el diseño de un proceso con alta velocidad de decantación y tiempo corto de retención.

El resultado es un proceso muy compacto, que requiere hasta 5 veces menos espacio de implantación que un decantador lamelar o una flotación por aire disuelto (DAF) y hasta 50 veces menos que un sistema de clarificación convencional.



 

 

 

 

 

 





 

 

 

 





### ACTIFLO™ process Alternative solution to storm tanks in a reduced implementation space

In order to treat the excess flow from the Crispijana WWTP during the rainy season, AMVISA, the municipal water company belonging to the Vitoria-Gasteiz City Council, promotes in 2011 a project for the construction of a rainwater treatment plant .

After roughing, sand removal and degreasing pretreatment, the new facility is designed for a maximum treatment capacity of 100,000 m3/day and has the ACTIFLO™ process for the removal of suspended solids, BOD, COD and phosphorus from raw water.

The operation and performance characteristics of the ACTIFLO™ process have been key factors for its choice in the Crispijana WWTP. The commissioning and full operation of the process is minimal, just 10 minutes, a highly important factor for the treatment of rainwater.

At the Crispijana WWTP, the ACTIFLO™ process has turned out to be an alternative solution to storm tanks that, in addition to requiring a reduced installation space, guarantees a high quality of the treated water. ACTIFLO™ makes wastewater storage unnecessary, thus avoiding the typical nuisances associated with these tanks.
