Patent number: 8480907Abstract: The invention relates to a method for the floatation-clarification of difficult water, in particular heavily polluted surface water, urban or industrial wastewater, rainwater or any type of water that floats with difficulty, particularly water which contains a high percentage of mineral matter or requires the injection of a flocculation aid and which originates from filters or membrane technologies such as ultrafiltration, said method comprising: a coagulation step (A1) in which a dose of coagulant (1) is injected into the water to be treated; a flocculation step (B) in which flocculant (2) is injected (B1) into the water after the coagulation step, in order to agglomerate the suspended particles in the form of flocs; and subsequently a floatation step (C) in which the flocculated water is mixed with an emulsion of air micro-bubbles in a floatation apparatus. A second coagulant injection step (A2) is performed downstream of the flocculant injection (B1) and upstream of the floatation (C).Type: GrantFiled: December 4, 2007Date of Patent: July 9, 2013Assignee: DegremontInventors: Patrick Vion, Céline Broutin, Christian Garriou

Patent number: 8460555Abstract: This invention reveals to the public the centralized sump oil and acid oil treatment process and system. The process consist of (1) the filter; (2) entry to reaction kettle, the sodium carbonate solution added at the time of air floatation till PH value keeps about 6.0-8.0; and emulsion splitter and flocculating agent added for further reaction; (3) suspension of air floatation and static settlement; (4) the international crude oil is collected after the detergent oil at the upper level of the reaction kettle is dehydrated under normal and reduced pressure; the wastewater is drained after filtering by the natural oil removal tank and the oil-water filter; the sludge is solidified by the cement and the quick lime and aluminium oxide are used as the coagulant aid for solidifying the sludge.Type: GrantFiled: June 24, 2010Date of Patent: June 11, 2013Inventor: Gang Yuan

METHOD FOR REMOVING POLLUTING SUBSTANCES FROM WATER STREAMS BY OXYGEN INJECTION IN A FLOTATION BASIN
Publication number: 20130140242Abstract: The injection of oxygen to a flotation basin in the process of removing pollutants from water streams comprising applying a flocculating or coagulating agent to a portion of the water stream, and creating a flocculation basin along the water stream. The injection of oxygen includes submitting the aggregate particles with higher dimension and density located upstream of the portion of the water stream to at least one of dissolving and injecting oxygen, directing same to dissolving plants through pressurized mixers, thus forming a water/oxygen mixture to be injected to portions of the water stream, causing the aggregate particles to float; creating a flotation basin along the portion of the water stream, the agglomerated material present upstream on the surface and by the banks of the water stream being removed by scraping the surface of the water stream.Type: ApplicationFiled: April 14, 2011Publication date: June 6, 2013Applicant: DTENGENHARIA DE EMPREENDIMENTOS LTDAInventors: João Carlos Gomes De Oliveira, Procópio Gomes De Oliveira Netto, Felipe Gomes Oliveira -
Patent number: 8444855Abstract: A method for removing contaminants from a fluid-material comprising: providing at least one substrate comprising a three-dimensional knit in an initial configuration made of knitted polymeric fiber which substantially resumes the initial configuration after it is released from stretching or compressing force; and submerging said at least one substrate in a fluidic material for treatment of the fluidic material.Type: GrantFiled: June 29, 2008Date of Patent: May 21, 2013Inventors: Jonah Gavrieli, Pinhas Hascalovich

Publication number: 20130092626Abstract: Uses of a method of producing small bubbles of gas in a liquid include gas transfer in airlift bioreactors and anaerobic digesters, and particle separation. The method uses a source of the gas under pressure, a conduit opening into a liquid and oscillating the gas passing along the conduit. The oscillation is effected by fluidic oscillator, comprising a diverter that divides the supply into respect outputs, each output being controlled by a control port, wherein the control ports are interconnected by a closed loop. Separation of algae from water involves delivering a laminar flow of microbubbles in the range 10 to 100 ?m diameter. Such bubbles also deliver a laminar flow in bioreactors that delivers enhanced liquid flow despite the small bubbles, which improves mixing and also enhances efficiency of gas exchange and retention of the bubbles in the reactor.Type: ApplicationFiled: October 15, 2012Publication date: April 18, 2013Applicant: Perlemax LtdInventor: Perlemax Ltd
