899 results about "Bioconversion" patented technology

Bioconversion, also known as biotransformation, is the conversion of organic materials, such as plant or animal waste, into usable products or energy sources by biological processes or agents, such as certain microorganisms. One example is the industrial production of cortisone, which one step is the bioconversion of progesterone to 11-alpha-Hydroxyprogesterone by Rhizopus nigricans. Another example is the bioconversion of glycerol to 1,3-propanediol, which is part of scientific research for many decades.

Process for the purification of acidic metal-bearing waste waters to permissable discharge levels with recovery of marketable metal products

Acidic metal-bearing wastewaters are treated to produce a finished water of sufficient purity to meet discharge standards while recovering metals removed in forms which are commercially valuable. The metals are selectively precipitated, either in a batch or in a continuous system, for removal of individual metal products in a specific sequence of steps from the wastewater. In each step, the pH is adjusted to the specific pH range and sulfide ion is introduced to precipitate the metals, excepting the removal of ferric iron and aluminum which is achieved using hydroxide precipitation. Bioconversion process using unique equipment converts sulfate in the wastewater to the hydrogen sulfide gas required for the precipitation process. This bioconversion process reduces the sulfate in the wastewater so that the water can be directly discharged or used for agricultural applications.

Dual Purpose Intermodal and Bioconversion Container

An Intermodal container, also known as an ISO Ocean Freight Container is suitable for the dual purposes of bio-containment and also Intermodal shipping. Provision is made for the introduction of water, oxygen or other liquids or gasses to be treated into the container, for exit of liquids or gasses generated or converted in the container, and for the monitoring of biological processes occurring within the container, all in a liquid impervious container. Improved air ducts and flow paths are provided, while the effects of shrinkage and channeling are reduced, through a strategically placed and relative percentage of openings through the floor. Further improvements in air distribution are achieved by an elimination or substantial reduction in percentage of opening through the floor in areas immediately adjacent to the container side walls. The flooring incorporates a self-cleaning hole design which increases in diameter with increasing distance from the container contents. The increases in diameter may be achieved either through smooth and continuous increases, or through discontinuous increments, though the objective regardless of the approach is to ensure that the holes do not clog either when the container is filled with matter, or when vibrated and jolted during handling and transport.
