Abstract: A fluid purification system (FPS) is provided and includes a fluid inlet, an injection manifold defining at least one manifold fluid flow path and at least one gas/fluid flow path. The injection manifold is configured to receive a fluid flowing into the fluid inlet such that the fluid flows through the manifold fluid flow path, wherein the injection manifold is configured to controllably divert at least a portion of the fluid to flow through the fluid/gas flow path and back into the manifold fluid flow path. The FPS further includes a singlet oxygen generator for generating singlet oxygen O1 communicated with the injection manifold such that the singlet oxygen O1 is controllably injectable into the gas/fluid flow path and a contact chamber, wherein the contact chamber is in flow communication with the manifold fluid flow path to receive the fluid flowing within the manifold fluid flow path.
