HUBER Hydro Filt Decentralised Stormwater Treatment
Sustainable treatment and infiltration of metal-containing stormwater runoff from metal roofs
- Adsorption of metals
- Cost-effective alternative to central plants
- Allows for installation under roadways
- Easy maintenance
- Long system life
The HUBER Hydro Filt is an innovative and efficient filter system for purification and subsequent filtration of rainwater containing metal from the roofs of buildings. The system consists of an upflow filter with the insert of a special filter material installed into concrete shafts approved specifically for the purpose of rainwater infiltration and the chemical-physical process of ion exchange removes metallic ions from the rainwater to be treated.
The special features of this filter system are its capability to virtually completely remove the high concentration of pollutants within the first flush at the beginning of a storm event, and its easy regenerability. Depending upon the filter utilisation rate and amount of roof runoff to be treated, the filter material is regenerated on site to re-establish its full adsorption capacity, or may be replaced.
