Bio-disc Technology
Bio-disc technology is an advanced wastewater treatment solution that leverages aerobic biological digestion combined with fixed biomass to purify effluent. This process utilizes discs that are partially submerged and rotate within the wastewater, ensuring that bacteria come into contact with the effluent, are oxygenated, and properly mixed. During the submerged phase, the fixed biomass on the discs extracts and breaks down organic and nitrogenous substances, enhancing the treatment efficiency. In the exposed phase, the bacteria receive the oxygen they need to survive. Any excessive or inactive biomass that detaches from the discs is separated out in the treated water during the final clarification stage using methods such as reed planted filters or static settling tanks. This bio-disc technology is scalable and can be used for populations ranging from 10 to 5,000 equivalent inhabitants, making it suitable for a wide range of applications.
Bio-disc technology is an extensive wastewater treatment process involving aerobic biological digestion with fixed biomass. The supports of the purifying microflora are discs partially immersed inside the effluent to be treated and animated by a rotational movement to ensure either the contact of the bacteria with the effluent, their oxygenation and mixing.
- In the immersed phase of the disc rotation cycle, the fixed biomass (fouling) removes organic and nitrogenous matter from the wastewater, then digests and degrades it.
- The emergent phase of the disc cycle allows the bacteria to breathe.
Excess or dead sludge, detached from the biological discs, ends up in the treated water, from which it is separated and then collected via a final clarification stage (reed planted filters, lamellar or static settling tank).
