摘要:
An electrolytic cell configuration to simultaneously treat a nitrogenous organic waste in the sediment as well as reduce a carcinogenic metal ion from both the sediment and the overlying supernatant phase. Apparatus and methods are disclosed to reduce hexavalent chromium (Cr +6 ) to a lower nontoxic state i.e. Cr +3 with an organic waste. The source of urea could be from the urea manufacturing plant, or the fecal discharge from any mammalian body (both human and animals), dialysis unit and fertilizer or agricultural runoff.

A method of deploying a containment boom is provided whereby an elongated material such as a sheet, yam, or yarn bundle, is formed into a roll and the material is pulled from the interior of the roll to create a helical structure. A pull rope is threaded through the interior of the roll and is deployed along with the material, such that the material is wrapped around the pull rope. The pull rope prevents the boom from stretching and distorting the helical structure formed by the material, as well as preventing the material from self-wringing. Multiple rolls of material may be provided in a single boom package arranged in coaxial alignment. When the materials are connected in parallel, they are integrated into a single boom having concentrically wrapped materials, thereby providing for greater stability and functionality.

A method for reducing nitrates, nitrites, and/or hydroxylaminc in water using a homogeneous reduced copper tetra-substituted fluorinated pinacolate ligand catalyst complex. The method includes dissolving a copper(II) tetra-substituted fluorinated pinacolate ligand pre-catalyst complex in water having an excess amount of nitrates, nitrites, and/or hydroxylamine therein. The dissolved copper(II) tetra-substituted fluorinated pinacolate ligand pre-catalyst complex in the water is subjected to electrochemical reduction to form a homogeneous reduced copper tetra-substituted fluorinated pinacolate ligand catalyst complex. The homogeneous reduced copper tetra-substituted fluorinated pinacolate ligand catalyst complex reduces the nitrates, nitrites, and/or hydroxylamine in the water to compounds with nitrogen in a lower oxidation state with the homogeneous reduced copper tetra-substituted fluorinated pinacolate ligand catalyst complex.
摘要:
Disclosed is a limonene-sulfur polysulfide and methods for preparing the same. The polysulfide prepared according to these methods is flexible, moldable and otherwise capable of being formed in any manner consistent with a thermoplastic polymer. The limonene-sulfur polysulfide has been demonstrated to sequester inorganic palladium and inorganic mercury dissolved in water.

Fusion proteins containing a targeting sequence, an exosporium protein, or an exosporium protein fragment that targets the fusion protein to the exosporium of a Bacillus cereus family member are provided. Recombinant Bacillus cereus family members expressing such fusion proteins are also provided. Genetically inactivated Bacillus cereus family members and recombinant Bacillus cereus family members that overexpress exosporium proteins are also provided. Seeds coated with the recombinant Bacillus cereus family members and methods for using the recombinant Bacillus cereus family members (e.g., for stimulating plant growth) are also provided. Various modifiations of the recombinant Bacillus cereus family members that express the fusion proteins are further provided. Fusion proteins comprising a spore coat protein and a protein or peptide of interest, recombinant bacteria that express such fusion proteins, seeds coated with such recombinant bacteria, and methods for using such recombinant bacteria (e.g., for stimulating plant growth) are also provided.
摘要:
A solar driven irrigation apparatus (2) for converting contaminated water contained in a contaminated water body (60) into distilled water and using said distilled water for irrigating the vegetation (136) grown on the said irrigation apparatus, the solar driven irrigation apparatus comprising a cover (8) in the form of a geometrical projection comprising a wall (12), an opening (16), a semi-permeable mesh (132), a soil layer (134) and a chamber (20), wherein, the wall is adapted to be in thermal communication with the external environment for capturing solar heat and in optical communication with the opening for allowing passage of solar rays from the external environment to the opening; the top of the wall is covered by a semi-permeable mesh which itself support a soil layer and the vegetation to be irrigated, the opening is adapted to be in optical communication with the wall and the surface of the contaminated water body for allowing passage of the solar rays from the wall to the surface of the contaminated water body for heating the contaminated water to form a vapor, and adapted to be in fluid communication with the surface of the contaminated water body and the chamber for allowing passage of the vapor from the surface of the contaminated water body inside the chamber; the chamber is defined by the wall, the chamber being adapted to be in fluid communication with the opening for receiving the vapor formed and allowing the vapor to pass through the semi permeable mesh located on the top of the wall such that said vapor passes through the soil layer thereby condensing said vapor for forming a distilled irrigation water.
摘要:
A mobile floating water treatment system comprising a plurality of floating barges coupled together wherein one or more barges includes at least one baffle through which water passes for treatment purposes. The baffle may include includes a substrate material suitable for treating contaminated water. The baffle may be selectively raised from an interior tank of the barges in order to add or subtract substrate material. The substrate material may include at least one of calcium carbonate, silicon dioxide, cadmium and bismuth. The mobile floating water treatment system may also comprise a tugboat for mobilizing the barges and a dredge for collecting contaminated water and distributing the water to the barges. The water treatment system may include one or more vessel or railcar located adjacent said barges into which contaminants separated from said water may be diverted for storage, transportation and disposal.
摘要:
The present invention describes an apparatus called the Fine Particle Shortwave Thrombotic Agglomeration Reactor (FPSTAR), which extracts waste from water without the need to add chemicals. The unprocessed water will be pulse fed to the reactor core having a Turbuliser. When Shortwave Resonance of different frequencies and high power is delivered to these reactors, soluble monomeric and polymeric complexes are formed. The finer particles that are present in the water substrate are subject to a special technique, which enables these particles to collide and agglomerate to form larger and heavier particles called Thrombus (clots).The liquid containing the clots is Thrombised liquid which is pumped through appropriate filtering systems to separate the clotted mass from the liquid. The reactor is used to decontaminate unprocessed water streams for reuse in the industry and other purposes and reduces the cost of water treatment, which also finds use in Oil and Mining Industries.
