CEBIOTREAT Project Objectives
The main purpose of CEBIOTREAT is to reduce the energy consumption in wastewater treatment plants (WWTPs) by 20% for conventional activated sludge WWTPs and by 40% for Moving Bed Biofilm Reactor (MBBR) WWTPs and to increase the efficiency of the biological stage.
A new type of aeration system based on fine-bubble diffusers with high endurance and reliability made from corrosion resistant metals will be developed. The diffusers will be realized using electroerosion. Also, CEBIOTREAT proposes a new automation solution for the aeration system, with mobile phone control. The diffusers will be designed to be use in all biological treatments, especially for the MBBR process, first developed in Norway (Ødegaard, 2013). The fine-bubbles diffusers will be also tested for conventional activated sludge WWTPs. The MBBR process needs a special aeration system because the biofilm carriers are floating inside the wastewater mass and butting the aeration system. More than that a new type of biofilm carrier will be designed and tested together with the new aeration system. The new biofilm carrier, proposed by CEBIOTREAT, will lead to an increase efficiency of the biological treatment stage.
In conclusion, the overall aim of CEBIOTREAT is to deliver a solution capable of achieving energy savings in WWTPs with minimum costs together with an increased biological treatment efficiency.
