Project description
Waste activated sludge as a resource
Waste water treatment plants produce large amounts of waste activated sludge (WAS) – an unwanted semi-solid residual. Upgrading waste water processes is a necessary step towards achieving the EU Green Deal goals. Considering WAS as a resource rather than an unwanted by product is crucial in this process. The ERC-funded CAVIPHY project will develop a unique device that exploits cavitation to pretreat industrial or domestic WAS before anaerobic digestion. However, this process needs to be fully modernised and refined to reach its full potential. The project will build on the knowledge gained by the ERC-CoG CABUM project that developed a cost-effective rotating generator for hydrodynamic cavitation that works simultaneously as a cavitation generator and a pump. CAVIPHY will improve WAS treatment while producing methane.
Objective
One of the most pressing global problems is the increasing pollution of surface and groundwater, which threatens the world's clean water supply and public health. Wastewater treatment plants (WWTPs), the last barrier between ever-increasing human activities and the environment, produce huge amounts, up to 13 million tonnes per year in the EU alone1, of unwanted semi-solid by-product - waste activated sludge (WAS). Therefore, upgrading wastewater (WW) processes with new circular economy approaches is crucial to achieve the goals of the EU Green Deal. Considering WAS as a resource rather than an unwanted end-product is the first step towards sustainable WW treatment. CAVIPHY will address this need directly by developing a unique device that exploits cavitation to pre-treat industrial or domestic WAS prior to anaerobic digestion (AD). However, this process, simple in its fundamentals, will never be sufficient to make a substantial contribution to current and future energy needs unless it is extensively modernized and refined to reach its full potential. Based on the knowledge gained within the ERC-CoG CABUM, we have developed a rotating generator for hydrodynamic cavitation (RGHC) - a scalable and cost-effective device that works simultaneously as a cavitation generator and a pump. With CAVIPHY, we will improve the disintegration, settleability and dewatering of WAS, resulting in synergistic effects in terms of lower costs associated with reduced volumes of WAS and environmental burden from its disposal, while producing methane – a renewable bioenergy source. This will have a direct impact on the economics of WWTPs, as the WAS associated costs already account for nearly half of the total WWTP operation expenses and will continue to increase.

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
