Project SUGGEREIX

Within the framework of the SUGGEREIX project, and based on the data provided by the ACA, a compilation of water reuse schemes in Catalonia was carried out, including the uses of reclaimed water, the treatment technologies applied (at European and global levels), and the monitoring conducted to ensure water quality in accordance with the regulations in force in each case.

Baix Llobregat water regeneration station

It is one of the largest water regeneration facilities in Europe and produces two qualities of water, for agricultural use and recharging of aquifers. Ensuring the quality of this water is a key factor in satisfying the water demand of the metropolitan area and preventing salt intrusion into the aquifers.

Tossa de Mar purification and reuse system

In a population that more than 10 times its number of inhabitants during the summer, this system works intermittently from the treatment plant itself, in order to provide water for irrigation uses of public green areas, cleaning of streets and maintenance of the ecological flow in the Tossa stream.

Samba Hotel in Lloret de Mar

It is a large hotel complex with 441 rooms, green areas and an outdoor swimming pool. He has previously participated in projects to implement innovative reuse technologies. It is therefore an excellent case study on how to encourage reuse to cope with the increasing demand for tourist facilities.

Project DECIDEIX

As part of the DECIDEIX project, a case study will be carry out.

DECIDEIX project

The DECIDEIX project includes a real-world case study at the Gavà-Viladecans Wastewater Treatment Plant (WWTP), where a new direct potable reuse (DPR) scheme is proposed through a pilot system based on a treatment train incorporating ozone, biological activated carbon (BAC), monochloramines, ultrafiltration (UF), reverse osmosis (RO), advanced oxidation processes (AOP) (UV/Cl), remineralization, and chlorination. The objective is to achieve high-quality reclaimed water and assess its incorporation into a direct potable reuse (DPR) scheme.

The pilot system has been designed with the aim of achieving water quality suitable for human consumption, in accordance with the parameters regulated by Royal Decree 3/2023, which establishes the technical and health criteria for the quality of drinking water, as well as its control and supply.
