  • Publication number: 20030085174
    Abstract: The invention relates to a sustainable process for treating contaminated fluids that utilizes a cellulose-based medium to adsorb contaminants in contaminated fluids and vapors. First, the cellulose-based material is tightly packed into a column. Contaminated fluid is then passed through the column to provide intimate contact between the contaminated fluid and the cellulose-based material. As the contaminated fluid flows through the column, the cellulose-based material adsorbs the contaminants (both organic and inorganic contaminants) due to the adsorptive properties of the cellulose-based material. The column is operated until the attenuation capacity of the cellulose-based material within the column is reached (i.e., when contaminants are found in the effluent). The cellulose-based material is then removed and composted and a new cellulose-based material is packed into the column. Composting is used to reduce the volume of the spent cellulose-based material and degrade and concentrate the contaminants.

  • Patent number: 6436288
    Abstract: The invention relates to a holistic sustainable wastewater treatment system that utilizes a bast medium as the attached growth medium. The wastewater treatment system of the present invention (Bast Medium Biological Reactor Treatment System) reduces odors and in-house ammonia levels and increases the overall water quality of organic waste streams. It uses naturally occurring microorganisms to process wastewater and remove odor without chemical augmentation. The Bast Medium Biological Reactor Treatment System is simple, with few moving parts and low maintenance requirements. The invention also relates to a method for treating wastewater using the wastewater treatment system according to the present invention.

  • Patent number: 4856148
    Abstract: Differential ginning is achieved by modifications to conventional saw-type ginning including, providing a saw gang including at least two saw sections each including at least one saw blade, conveying of material to be ginned (e.g. seed cotton) successively to each section, ginning of the material in each section so as to separate a portion of lint from the material, and separate removal of lint from each section. Thereby producing portions of lint, wherein the fiber qualities vary from portion to portion e.g. separating longer fibers from shorter fibers.
