Abstract: A detoxification method includes the steps of inducing flow of patient blood through an extracorporeal device inlet and outlet in fluid connection to the circulatory system of a patient. Biological agents including lipopolysaccharide (LPS) contained within patient blood can be detoxified by passing patient blood over a biochemical reactor surface having attached or immobilized Saccharomyces boulardii alkaline phosphatase enzyme, with the biochemical reactor being contained within the extracorporeal device. An acyloxyacyl hydrolase enzyme may also be used on the biochemical reactor surface.

Abstract: Selected freshwater or saltwater aquaculture systems are processed for the automatic removal of waste, ammonia, and pathogens while controlling temperature, oxygen, and feed amounts for obtaining maximum growth and survival at maximum aquatic species densities. A core platform treatment technology removes ammonia by combining chlorine with the ammonia to form chloramines, which are removed by catalytic activated carbon at a downstream filter station. Processing also removes potential pathogens by sterilizing and electrifying the water. The technology utilizes ammonia, chlorine, oxidation-reduction potential (ORP), and flow sensors to electronically adjust the amount of chlorine needed to remove the existing ammonia. A control system utilizes temperature, dissolved oxygen, and image processing sensors to optimize heating, cooling, feeding, and aeration.

The server also updates a UF trend using previous amounts of UF removed from the patient and the amount of UF removed from the patient during the most recent dialysis treatment and generates an alert if the UF trend changes by more than a preset percentage.

Abstract: A system, process and method for remediating contaminated soil and solvent recovery. A solvent mixture including a polar and a non-polar solvent is mixed with contaminated soil in mixing vessels, allowing the solvent mixture to extract contaminates from the soil. The solvent mixture is separated from the soil using bicanting units to form a solvent stream and a soil stream. The soil stream goes through air sparging in a dryer to remove residual solvent vapor. Water and/or micro-fines are extracted from the solvent stream using a centrifuge. The solvent stream undergoes distillation in a distillation unit to remove the containments from the solvent stream, while recovering separately the solvent mixture and a product. The recovered solvent mixture can be recycled back to the mixing vessels. The contaminates can be BTEX or F1-F4 hydrocarbons, and the product can be oil or other hydrocarbons. The system can be mobile.
