Treating By Enzyme Patents (Class 210/632)
  • Patent number: 10858273
    Abstract: A method and system of treatment of agricultural and industrial wastewaters that contain high concentrations of suspended solids, nitrogen, and phosphorus compounds is disclosed. The method and system includes pre-treating the wastewater, controlling the amount of coagulants used, and controlling the mean velocity used for mixing, surface loading rate, and solids loading rate. The method and system functions as a sedimentation unit and gas flotation unit (solid/liquid separator). The pH of the effluent wastewater is stabilized within the separator by ensuring that there is sufficient alkalinity to buffer the wastewater. Sufficient gas is produced in the coagulation reactions to float and concentrate the solids, which results in as high as 99 percent reduction in suspended solids, a 96 percent reduction of the phosphorus concentration, and a 50 percent reduction of the nitrogen concentration in the effluent from the separator.

  • Patent number: 9352284
    Abstract: This disclosure examines using alginate lyase to catalytically degrade alginate in order to decrease affinity and fouling potential to membranes of 0.2 and 0.02 ?m pore size, respectively within a process line of a filtration system. Enzymatically treated alginate caused less fouling on both ultrafiltration and microfiltration membranes than original alginate. Enzymatically treated alginate is predicted to cause less fouling on both membranes within the pH range of approximately 3.0 to approximately 10.0. Without the presence of calcium cation, alginate lyase reduced the foulant resistance by more than 82% for both membranes. In the presence of 1 mM calcium cation, alginate lyase reduced the foulant resistance by more than 55%. In addition, the foulant structure composed of enzymatically treated alginate was more readily removed by backwashing, suggesting reversible fouling. The advantages of using enzymatic technique to control membrane fouling include high efficiency and no damage to the membrane materials.

    Abstract: A method for removal of at least a portion of carbon dioxide from an aqueous fluid such as a blood fluid includes placing a first surface of at least one membrane through which carbon dioxide and at least one acid gas other than carbon dioxide can pass in fluid in contact with the fluid. The membrane limits or prevent passage of the fluid therethrough. A carrier or sweep gas including the acid gas other than carbon dioxide is passed over a second surface (which is typically opposite the first surface) of the membrane so that the acid gas other than carbon dioxide can pass through the membrane into the fluid, and carbon dioxide from the fluid can pass from the liquid, through the membrane, and into the sweep gas.

    Abstract: A process has been found which increases the efficiency and effectiveness of introducing antimicrobial compounds into complex biofilm matrices through the use of liposome carriers, thereby removing the biofouling in industrial water bearing systems, including piping, heat exchanges, condensers, filtration systems and fluid storage tanks. According to one embodiment of the invention, antimicrobial compound containing liposomes are added to water systems prone to biofouling and biofilm formation. The liposomes, being similar in composition to microbial membranes or cells, are readily incorporated into the existing biofilm. Once the antimicrobial compound containing liposomes become entrained with the biofilm matrix, the decomposition or programmed disintegration of the liposome proceeds. Thereafter, the biocidal aqueous core is released to react directly with the biofilm encased microorganisms.

  • Publication number: 20140097138
    Abstract: A system and method includes an aeration subsystem that excites enzymes in the liquid waste passing through the septic system. The aeration subsystem includes a compressor section that compresses the liquid waste. The method includes mixing enzymes into the fluid waste material, compressing the fluid waste material with the compressor, injecting air into the compressed fluid waste material, and determining whether the fluid waste material is at a desired cleanliness, and if not, recirculating the fluid waste material through the compressor.

  • Patent number: 8690993
    Abstract: The present invention provides a method and apparatus for the treatment of process gas from an anaerobic digestion system or a landfill gas system. In one embodiment, the system comprises a caustic scrubber including a vertical column having a top and a bottom and including a counter current flow system, wherein a process gas stream flows up vertically through the column in counter current flow to a caustic liquid solution that flows downward through the column. The caustic liquid solution removes at least one acid from the process gas stream, wherein treated gas that is substantially free of acids bubbles out through an opening at the top of the vertical column.

  • Publication number: 20140061127
    Abstract: The invention presents a urea bio-electrochemical (UBE) system to achieve resource recovery from water recycling systems. A GAC-urease bioreactor was used to recover urea from wastewater stream, and converted to ammonia. Then, the ammonia produced was used to feed an electrochemical cell to gather electrical energy. The invention shows the feasibility of using the UBE system in combination with a forward osmosis subsystem for water reclamation.

  • Publication number: 20140004583
    Abstract: A composition comprising mesoporous aggregates of magnetic nanoparticles and free-radical producing enzyme (i.e., enzyme-bound mesoporous aggregates), wherein the mesoporous aggregates of magnetic nanoparticles have mesopores in which the free-radical-producing enzyme is embedded. Methods for synthesizing the enzyme-bound mesoporous aggregates are also described. Processes that use said enzyme-bound mesoporous aggregates for depolymerizing lignin, removing aromatic contaminants from water, and polymerizing monomers polymerizable by a free-radical reaction are also described.
