A Novel compact and Advanced hybrid Microalgae-membrane photobioreactor Optimized for Retrofitting decentralized water and wastewater management systems (NAMOR).

The NAMOR project promotes a next-generation water treatment solution that combines microalgae-bacteria co-cultivation with advanced membrane filtration in a modular plug-and-play system. This innovative approach allows for the decentralized treatment of various water and wastewater streams, supporting a sustainable and resilient urban water cycle. NAMOR’s hybrid system is designed for maximum adaptability, with demonstrations in three different climatic zones — high, medium, and low temperatures — under varying lighting conditions, ensuring robust performance across a wide range of environmental scenarios. The system will provide high-quality, fit-for-purpose effluents with minimal energy consumption and low environmental impact, enhancing urban water management. It will integrate seamlessly into existing centralized networks while enabling site-specific local treatment. Furthermore, the produced biomass will be efficiently valorized for nutrient and energy recovery, contributing to a circular economy.

At the core of NAMOR’s innovation lies the development of a digital twin model equipped with a sensor network and predictive analytics tools to monitor and forecast system performance in real time. This is complemented by a Decision Support System that optimizes energy efficiency and maximizes water and nutrient recovery, adapting to specific local requirements. NAMOR also places great importance on citizen engagement and the social acceptance of decentralized water solutions. Through an inclusive and participatory approach, citizens are actively involved from planning to implementation. Social science methods will be employed to assess public opinion and the willingness to adopt these systems, while specific policy recommendations will foster greater public participation.

Additionally, NAMOR is analyzing the global market and regulatory framework to adapt its solutions to international contexts, thus positioning itself as a pioneering solution for future urban water systems worldwide.
