Abstract
A liquid purification system is provided. Although not limited to water, the purification system is especially suitable for water. The purification system utilizes a vessel having antimicrobial inner wall load bearing surfaces and/or antimicrobial (antibacterial, anti-fungal, anti-mold, etc.) interior non-load bearing surfaces. When the liquid moves within the vessel and contacts the antimicrobial surfaces, the liquid becomes purified or sanitized. The inner wall load bearing surfaces and non-load bearing interior surfaces of the vessel may be manufactured from a host polymer that has antimicrobial organo-metallic additives which form a solid-solution with the host polymer and are distributed homogeneously throughout the host polymer. The host polymer matrix may be an organic material, an inorganic material or an organic-inorganic material blend. The antimicrobial agent polymer matrix may be located in localized zones within the vessel.
