Main Applications

  • Drinking water from surface water:During warm seasons, these waters are high in algae and organic matter, which are perfectly tackled by our Flotofilter.

  • Drinking water production from borehole water: Requires clarification before sand filtration to prevent an occasional increase in the turbidity and extend the operation cycle of the sand filters.

  • Tertiary treatment for hard COD and phosphorus removal
