Abstract: A water purifier includes a chamber having a perimetric wall, a bottom wall at a first end, and an opening at a second, opposed end. A collection pipe extends along the bottom wall. A siphon pipe fluidly coupled with the collection pipe extends along the perimetric wall away from the bottom wall. An exit pipe fluidly coupled with the siphon pipe extends through a perimetric wall discharge opening. A layer of granular material in the chamber contains and sustains a biological layer of microorganisms for reducing water-borne pathogenic microorganisms. An inorganic anti-microbial disinfectant source is incorporated into a portion of the granular material. The granular material and biological layer provide progressive biochemical remediation of pathogenic microorganisms. The inorganic disinfectant source provides progressive chemical and biochemical remediation of pathogenic microorganisms.

Abstract: A water purification reactor comprises a containment vessel holding a water purification medium and a disinfectant, and a discharge assembly. The containment vessel has a perimetric wall with a discharge opening therethrough, a first end having a bottom wall, and a second opposed end defining an opening. The perimetric wall and the bottom wall define a chamber. The discharge assembly comprises a collection pipe extending along the bottom wall, a siphon pipe fluidly coupled with the collection pipe and extending upwardly along the perimetric wall, and an exit pipe fluidly coupled with the siphon pipe and extending through the discharge opening. The water purification medium comprises at least one layer of granular material contained within the chamber. The disinfectant has anti-microbial properties and is incorporated into a portion of the water purification medium. The water purification medium and disinfectant are adapted for progressive chemical and biochemical remediation water.
