Biodiscs

Challenge

To address the deficiencies and limitations of conventional biodisc technology to improve biological nutrient removal and effluent quality.

Solution

Development of a hybrid biodisc system with biological nutrient removal, consisting of an active sludge reactor with anaerobic and anoxic chambers followed by a hybrid biodisk reactor (which combines biomass in suspension and in biofilm) and secondary settlement.

Main Data

Development of an innovative and low-cost integrated biological process for the elimination of nutrients in wastewater treatment plants.
