Publication number: 20110059053Abstract: A method of treating biocells includes the steps of: a. providing biocells; b. applying at least one stressor to the biocells sufficient to cause nonlethal and reparable cell wall damage to the biocells, thereby putting the biocells in a catabolic state during which catabolic metabolic functions predominate over anabolic metabolic functions; and c. obtaining at least one product produced by the biocells during the catabolic state. In another embodiment, the method includes the steps of: a. providing biocells that are mammalian cells; b. applying at least one stressor to the biocells sufficient to cause nonlethal and reparable cell wall damage to the biocells, the reparable cell wall damage comprising openings that allow increased passage of materials through the cells walls; and c. inserting foreign DNA through the openings into the biocells.Type: ApplicationFiled: September 7, 2010Publication date: March 10, 2011Applicant: Battelle Memorial InstituteInventors: Satya P.

Publication number: 20100176061Abstract: The invention provides an efficient method to purify an aqueous solution, typically mine drainage water, especially of anions and cations present in the aqueous solution as dissolved solids, the anions and cations are removed by treatment with a positively charged extractant having at least eight carbon atoms, whereby an unstable emulsion is formed; the unstable emulsion is allowed to break into an extract phase loaded with the anions and cations, and a water phase depleted in anions and cations; a floe inherently forms in the loaded extractant phase and then the loaded extractant phase and floe are separated from the purified water and treated to remove the anions and cations as concentrated useful products; the treated aqueous phase now reduced in anion and/or cation content is also separated from the emulsion as a purified aqueous solution. The extractant phase is preferably recycled. A continuous water purification process is provided.Type: ApplicationFiled: February 14, 2008Publication date: July 15, 2010Inventors: Bruce F. Monzyk, F.

Patent number: 7048871Abstract: In a process for producing a deicing/anti-icing fluid, a byproduct stream is obtained from a process that produces monoalkyl esters of long chain fatty acids. The stream includes water, glycerol, and an alkali-containing compound. The stream is converted to a deicing/anti-icing fluid by adding an acid to the stream to neutralize the alkali-containing compound to produce an alkali salt that functions as a supplemental freezing point depressant.Type: GrantFiled: November 3, 2004Date of Patent: May 23, 2006Assignee: Battelle Memorial InstituteInventors: Satya P.

Patent number: 6540919Abstract: A system that allows the flexibility of primary and secondary treatment of municipal sludge, paper-pulp sludge, animal and plant waste, whereby the treatment thereof via electroporation may be used either as the primary dewatering treatment, secondary dewatering treatment, direct WAS-treatment, and combinations with other conventional dewatering techniques, in order to provide the municipal treatment plant, or the paper-pulp treatment plant, with the most cost-effective and efficient system as possible. The electroporated-treated sludge releases hitherto unreleased biosolids exiting from the PEF-electroporation system, which are returned to aeration tanks. The electroporation process causes the release of intracellular dissolved/organic matter, which is used as “food” for the bacteria of the aeration tanks.Type: GrantFiled: March 26, 2002Date of Patent: April 1, 2003Assignee: DH20 L.L.C.Inventors: Jeffry Held, Satya P.

Patent number: 6491820Abstract: The present invention is directed to a pulsed electric-field system for rupturing and destroying molecular cellular units of waste-activated sludge to thereby liberate intracellular water molecules from the solids-content thereof. The waste-activated sludge is contained in waste sludge, such as paper-pulp sludge, municipal waste sludge, animal or plant waste sludge. The pulsed-electric field is generated by an electroporating device producing a non-arcing pulsed electric field. The released intracellular dissolved/organic matter may be recycled back to an aeration tank for supplying food to bacteria of the aeration tank for performing aerobic digestion thereon, whereby the intracellular, dissolved organic matter is used as food for the bacteria of the aeration tank, whereby the aerobic digestion process is accelerated.Type: GrantFiled: December 3, 2001Date of Patent: December 10, 2002Assignee: DH20 L.L.C.Inventors: Jeffry Held, Satya P.
