Photocatalytic fluid purification systems
The Invention describes LED illuminated photocatalytic fluid purification systems, especially for use for ethylene mitigation and control in agricultural, horticultural and floricultural growth, storage and transport modules. Aspects of the invention include systems integration with grow lights, ethylene and plant stress sensors, and communication with external control and data sources.
1. A plant logistics module, comprising an integrated photocatalytic ethylene mitigation system, wherein light emitting diodes (LEDs) provide the photocatalytic illumination to drive the photocatalytic ethylene mitigation system, further comprising a porous monolithic composite photocatalyst comprising titanium oxide, wherein the monolithic composite photocatalyst is modified to achieve optical absorbance greater than 10% at a wavelength of approximately 405 nm for a monolithic composite photocatalyst material thickness of 8 mm.
2. The module of claim 1 , wherein the titanium oxide is primarily anatase phase.
3. The module of claim 1 , wherein the titanium oxide is formed in islands in the porous monolithic composite photocatalyst.
