A water purification system utilizes a continuously recirculating water loop to provide clean water for consumption by animals or humans. The system includes filtration, ozone treatment, and optional alkaline water processing to improve water quality. An electromagnetic water treatment apparatus is integrated with piping carrying the water and is configured to emit electromagnetic waves at predefined frequencies to induce fields within the pipe and flowing water. These fields break down and prevent accumulation of rust, scale, biofilm, and microbial and chemical contaminants. The electromagnetic apparatus may be positioned at various locations within the system, including upstream of purification components to enhance performance and reduce fouling. The system thereby improves purification efficiency, maintains pipe integrity, and supports delivery of cleaner, safer water through continuous treatment and recirculation.
