Patent number: 10053379Abstract: An integrated device for wastewater purification, comprising a coagulation zone; a flocculation zone connected to and in fluid communication with the coagulation zone; a flotation zone connected to and in fluid communication with the flocculation zone and comprising a froth discharge port; and a separation zone below and in fluid communication with the flotation zone and comprising a contaminant separator and a purified wastewater discharge port; the wastewater entering the device being mixed with electrolytically-generated coagulants and gas bubbles in the coagulation zone; the flocculation zone receiving and gently mixes coagulated wastewater contaminants and gas bubbles formed in the coagulation zone and aggregating them into flocs before flotation of buoyant flocs in the flotation zone and the separation zone being adapted for further floc formation, oil coalescence, settling and discharge of non-buoyant contaminants.Type: GrantFiled: February 16, 2017Date of Patent: August 21, 2018Assignee: PROTERRGO INC.Inventors: Panayotis G. Tsantrizos, Valérie Léveillé, Nicole A. Poirier, Roy Richard

Patent number: 9657941Abstract: The gasifier operates to mix a start up heat source with crude syngas combustion for driving gasification of waste. Combustion flue gas can be maintained above 650° C. until reaching a quench to prevent formation of dioxins. Excess heat is liberated through a heat recovery unit. The gasifier can operate in a batch mode to process small batches of waste efficiently for small installations, such as ships, apartment buildings, hospitals and residences.Type: GrantFiled: April 19, 2010Date of Patent: May 23, 2017Assignee: PROTERRGO INC.Inventors: Panayotis Tsantrizos, Stephan Lavigne

Patent number: 9139785Abstract: A gasification reactor for processing organic waste in batches comprises a primary gasification reactor (62) that includes a primary gasification chamber (18) and a surrounding combustion chamber (19), a secondary gasification chamber (21), a synthesis gas decontamination unit (42) and a combustible gas selector (41). The waste is loaded into the primary gasification chamber through a latched opening and heated from the combustion of a fuel in the combustion chamber (19) to convert the waste to a synthesis gas. The gasification chamber (18) has an intake (20) for introducing pre-heated process air (1) therein. The combustion chamber operates either with a conventional fuel (9) or with the produced synthesis gas (6). The secondary gasification chamber (21) thermally treats the synthesis gas (2) to eliminate tars. The decontamination unit (42) scrubs the synthesis gas of contaminants including particulates and acid gases.Type: GrantFiled: October 12, 2007Date of Patent: September 22, 2015Assignee: PROTERRGO, INC.Inventor: Panayotis Tsantrizos

Publication number: 20120160706Abstract: The wastewater treatment apparatus of present invention has an electro-coagulation unit for removing contaminants with at least one anode and at least one cathode and an electro-oxidation unit for oxidizing contaminants with at least one anode and at least one cathode wherein oxidants are electrochemically generated. Based on the type of wastewater, the apparatus can have an electro-flotation unit between the electro-coagulation unit and the electro-oxidation unit. The apparatus also has an oxidant removal unit which can have a metal ion-liberating electrode for reacting with and removing residual oxidants. In some cases, portions of effluent from the oxidant removal unit can be recirculated to the electro-coagulation unit for increased efficiency.Type: ApplicationFiled: June 23, 2010Publication date: June 28, 2012Applicant: PROTERRGO INC.Inventors: Nicole A.
