Gavá – Viladecans (Extension and Tertiary)

Cadagua took on this major modernization project of the treatment plant of Gava Viladecans, with the objective of ensuring the compliance with the new European requirements for discharges in sensitive areas, and to enable them to be reused in the natural environment.

The obsolete conventional active sludge processes were retrofitted with two parallel processes; a membrane bioreactor (MBR) and an hybrid fixed-film activated sludge (IFAS) with mobile support media treatment system. Each line has a capacity of 32,000 m3/d.
