A self-contained hydroponic growing enclosure and method for the fabrication of animal feed grass from seed is described. The enclosure is a self-contained enclosure which is insulated and which can be transported or assembled on site and which is independent of outside climatic conditions. Seed is stored in an isolated portion of the enclosure and fed to germination tanks in predetermined quantities where the seeds are germinated for a predetermined period of time. The tanks are then drained of their iodine-treated water and the germinated seeds are placed in predetermined quantities onto trays which are placed at an inlet end of a racking system. Trays are removed with grown grass at a harvest outlet end of the racking system in the same sequence as they are placed at the inlet end, so that there is a continuous daily supply of feed grass. Light walls are provided on opposed sides of the racking system to illuminate the beds. Conditioned air is also convected through the racking system from the inlet end to the outlet harvest end and the air flow distributes carbon dioxide generated in an inlet end section by the germinating seed grain, over the entire growing beds. The beds are also sprayed with water and the air flow is reconditioned by an air conditioning unit, filtered to remove bacteria and recirculated through the racking system. More specifically, the production system uses feed-quality barley for growing in tray beds to produce approximately 2,200 pounds of feed grass per day in a 7-day cycle from seed to feed.

A system and method for enhancing the flux and separation properties of water filtration membranes by oxidizing raw or processed water constituents with direct photolysis of the water matrix by pulsed blackbody UV, yielding ozone and hydrogen peroxide, hydroxyl radicals and other short lived oxidizing species. The result thereof, causing precipitation of inorganic molecules or organically complexed minerals, partial or complete mineralization of organic molecules and the deactivation or destruction of microbes including: virus, bacteria and protozoa. The system and method comprises a pulsed blackbody, deep-UV reactor having at least one treatment chamber, the reactor having a conveying assembly to convey the water to be treated into the chamber; a filter assembly to screen the UV treated water; a caustic supply means for the post-treatment of water; a recovering assembly recovering the permeate at an outlet of the filtration means. The effect of such UV water treatment is multifaceted. One aspect is the reduction of the transmembrane pressure (TMP), another is the reduction of duration of backwash and caustic cleaning cycles. Also, the oxidation of iron and manganese to insoluble compounds, without the addition of oxidizing agents, does not harm the membranes. Iron and manganese turn into hydroxide crystals trapped by the filtration membrane and separated from the permeate. These effects integrate to enhance the water flux through the filter membrane.
