Controlling Biofouling In Governador José Richa Power Plant, Brazil

An extensive study was carried out between May 2022 and July 2023 to evaluate the ability of the HOD™ (Hydro-Optic Disinfection) HOD UV system to control biofouling in the Governador José Richa Power Plant owned by Companhia Paranaense de Energia (COPEL), located on the Iguaçu River, Paraná, Brazil. The plant has four 310 MW generating units totaling 1240 MW.

UV radiation is widely used to eliminate microorganisms in water and has a history of many studies for its use in water for human consumption, without causing damage to water quality. The HOD UV system has already been reviewed by federal agencies (Oficio MAPA No. 57/2018/CGAA and Oficio IBAMA No. 336/2020/DIQUA) to authorize its use.

The pilot installation at the Gobernador José Richa Plant featured Atlantium’s HOD UV system.
