A STUDY OF NEW ANTI-FOULING TECHNOLOGY USING THE CATALYTIC PROPERTIES OF TITANIUM IN MINERAL FOULING MITIGATION
Abstract
The present study investigated the performance of physical water treatment (PWT) device using titanium balls for the mitigation of mineral fouling. A concentric tube heat exchanger in a counterflow set-up was utilized. Different water velocities of 0.3 m/s, 0.5 m/s, and 0.8 m/s were used to investigate their effect on the performance of the PWT device using titanium balls. The results showed that PWT-treated cases had 24.6−30% lower fouling resistances as compared to the untreated cases depending on the flow velocity and electrical conductivity. The SEM photographs of the deposits in the Ti-treated cases also revealed calcite form of scale that could easily be carried away by fluid flow shear forces.
