This technology offers several advantages over traditional water purification methods. For instance, it reduces the need for chemical additives, thereby minimizing secondary pollution. Furthermore, TIO2's stability, non-toxicity, and ability to function under ambient conditions make it an ideal choice for large-scale water treatment facilities. By integrating TIO2 into their operational framework, water factories can achieve higher purity output while significantly lowering energy consumption and operational costs.

Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.
