Anaerobic Fermentation To Produce Biogas

View page
US Patent:
20120145627, Jun 14, 2012
Filed:
Feb 18, 2010
Appl. No.:
13/201863
Inventors:
Andrew Benedek - Rancho Santa Fe CA, US
Assignee:
ANAERGIA INC. - Burlington ON
International Classification:
C02F 11/04
B01D 61/00
US Classification:
210601
Abstract:
A process and apparatus for the anaerobic digestion of organic wastes, preferably to also produce a useful biogas, is described. The waste may have a total solids (TS) concentration of 6% or less while a digester is operated at a higher solids concentration, for example with a feed TS concentration of 8-12%. One or more separation stages downstream of the digester separate active bacteria and undigested orgaπics from the digestate, and return separated matter to the digester. Optionally, a feed thickening apparatus and step may be provided upstream of the digester. The upstream thickener and recycle form the downstream separation stages are operated such that the TS of the combined inputs to the digester is within a desired range.

US Patent:
20130203144, Aug 8, 2013
Filed:
Mar 14, 2013
Appl. No.:
13/826507
Inventors:
Anaergia Inc. - Burlington, CA
Andrew BENEDEK - Rancho Santa Fe CA, US
Assignee:
ANAERGIA INC. - Burlington
International Classification:
C12P 5/02
C02F 3/12
US Classification:
435167, 13756501
Abstract:
An anaerobic digester is fed a feedstock, for example sludge from a municipal wastewater treatment plant, and produces a digestate. The digestate is dewatered into a cake. The cake may be dried further, for example in a thermal drier. The cake is treated in a pyrolysis system to produce a synthesis gas and biochar. The gas is sent to the same or another digester to increase its methane production. The char may be used as a soil enhancer.

Treatment Of Municipal Wastewater With Anaerobic Digestion

US Patent:
20130213883, Aug 22, 2013
Filed:
Aug 12, 2011
Appl. No.:
13/814964
Inventors:
Juan Carlos Josse - Mission Viejo CA, US
Andrew Benedek - Rancho Santa Fe CA, US
Assignee:
ANAERGIA INC. - Burlington ON
International Classification:
C02F 9/00
US Classification:
210630, 210631, 210601
Abstract:
Low strength wastewater such as municipal sewage is treated using an anaerobic digester. In some examples, a wastewater stream is separated into a solids rich portion and a solids lean portion. The solids lean portion is treated, for example to remove nitrogen. The solids rich portion is treated in an anaerobic digester, preferably with influent or recuperative thickening. In another example, the wastewater stream is fed to an anaerobic digester and solid-liquid separation stages downstream of the di-gester return active bacteria and undigested organics to the digester. Both cases may use a process train comprising treatment in an anoxic tank followed by a nitritation tank with a portion of the effluent from the nitritation tank recirculated to the anoxic tank to provide nitritation and denitritation.

Organics And Nutrient Recovery From Anaerobic Digester Residues

US Patent:
20140033776, Feb 6, 2014
Filed:
Feb 17, 2012
Appl. No.:
13/982585
Inventors:
Juan Carlos Josse - Mission Viejo CA, US
Andrew Benedek - Rancho Santa Fe CA, US
Michael David Theodoulou - Milton, CA
Zachary Scott - La Jolla CA, US
Assignee:
ANAERGIA INC. - Burlington ON
International Classification:
C05C 3/00
C02F 11/04
US Classification:
71 10, 210607, 210179, 210178, 210151, 71 13
Abstract:
Sludge from an anaerobic digester is treated to recover one or more of fibers, or solids or liquids with a high nutrient content. The solids or liquids can be used as a fertilizer. The fibers can be used in a plant growing medium. Solids are separated from liquids in the sludge and dried. The solids may be dried to produce a flake or pellet. Ammonia in the liquids is recovered and used to produce a concentrated acidic ammonium salt solution. This solution may be mixed with the solids to produce a nitrogen enhanced solid. The fibers and solids or liquids can also be used in combination to produce an enhanced plant growing medium. A device and process for removing ammonia from a liquid can be used in the system or separately.

Treatment Of Waste Products With Anaerobic Digestion

US Patent:
20140034574, Feb 6, 2014
Filed:
Nov 22, 2011
Appl. No.:
13/982598
Inventors:
Juan Carlos Josse - Mission Viejo CA, US
Andrew Benedek - Rancho Santa Fe CA, US
Assignee:
ANAERGIA INC. - Burlington ON
International Classification:
C02F 11/04
US Classification:
210609, 210601
Abstract:
A waste stream is treated by anaerobic digestion. A process is described involves a step of separating solids from digestate, and returning separated solids to a digester. Optionally, there may be a step of solids separation in which larger solids are removed from the digester. A process and apparatus are described for treating waste sludge from a wastewater treatment plant in an anaerobic digester. Feed sludge is thickened or solids are separated from digestate and returned to the digester. Additional co-digestion waste may be added to the digester. The process and apparatus may be used in a retrofit of an existing wastewater treatment plant.

Process For Recovering Organics From Material Recovery Facility Fines

View page
US Patent:
20200101506, Apr 2, 2020
Filed:
Mar 23, 2018
Appl. No.:
16/497407
Inventors:
- Burlington, CA
Andrew BENEDEK - Rancho Santa Fe CA, US
International Classification:
B09B 3/00
B30B 9/04
Abstract:
A system and process for separating organic material from solid waste such as material recovery facility (MRF) fines is disclosed. The fines are treated in a press, in which the fines are compressed against a wall having a set of holes. The fines are mixed with a substantial amount of water before being pressed. The water increases the amount of organic matter that is recovered from the fines. A wet fraction, extruded through the holes of the press, may be treated in an anaerobic digester.

Solid Waste Processing With Diversion Of Cellulosic Waste

View page
US Patent:
20180002207, Jan 4, 2018
Filed:
Sep 15, 2017
Appl. No.:
15/705704
Inventors:
- Burlington, CA
Andrew BENEDEK - Rancho Santa Fe CA, US
International Classification:
C02F 3/28
D21B 1/02
D21C 5/00
D21H 11/14
Abstract:
Waste, such as municipal solid waste (MSF), is separated into a wet fraction and rejects. For example, the waste may be separated in a press. A cellulosic fraction is separated from the rejects. In a wet method the rejects are treated in a pulper to extract the cellulosic fraction. In a dry method, the rejects are treated with an optical sorter. The cellulosic fraction is treated in an anaerobic digester, optionally with the wet fraction.
