VITAQUA has developed a compact system of purification plants for urban wastewater that incorporates biological treatment with BIODISCS VIT.

BIODISCS VIT treatment achieves a reduction of 93% of BOD5 at the end of each stage.

The main advantage of the BIODISCS VIT system is its very low energy cost compared to a conventional extended aeration system. The system of bio-discs BIODISCS VIT consumes a fifth part of energy thanks to it only works with a very low power engine.

This energy optimization coupled with low sludge production and the negligible number of spare parts or consumables necessary, makes operating and maintenance costs the most competitive coupled with the contact beds of high surface BIOFILT®.
