WAT ER A ND WAST EWAT ER The benefits of thermal-sprayed coatings in water turbines Surfaces for longer life and higher energy efficiency Hydroelectric power contributes importantly towards the expansion of renewable energy sources. Sulzer Metco coatings protect many water turbine components from erosion and corrosion damage; thus, they contribute to a safe, economical, and environmentally friendly energy supply. ccording to the orld Energy Out- the emerging markets.

The study predicts an overall electricity production will increase 35% higher in 2035 than in 2008 as a increase in oil consumption of only from 19% in 2008 to 32% in 2035.
