Publication number: 20240091708Abstract: Wastewater is treated though primary treatment of the water by way of a micro-sieve to produce a primary effluent and primary sludge. There is secondary treatment of the primary effluent by way of a membrane bioreactor (MBR) or an integrated fixed film activated sludge (IFAS) reactor to produce a secondary effluent and a waste activated sludge. The micro-sieve may have openings of 250 microns or less, for example about 150 microns. In a process, a gas transfer membrane is immersed in water. Pressurized air flows into the gas transfer membrane. An exhaust gas is withdrawn from the gas transfer membrane and used to produce bubbles from an aerator immersed in the water.Type: ApplicationFiled: November 14, 2023Publication date: March 21, 2024Inventors: Pierre Lucien COTE, Steven Kristian PEDERSEN, Wajahat Hussain SYED, Jeffrey Gerard PEETERS, Nicholas William H.

Patent number: 11673820Abstract: A hybrid membrane aerated biofilm reactor (MABR) and activated sludge (AS) system and process are described herein. At least a portion of the AS system includes aerobic mixed liquor, for example in an aerobic tank or zone downstream of a tank or zone containing membrane aerated biofilm modules. The flow of air to the membrane aerated biofilm is modulated considering the ammonia loading rate to the system or to the aerobic mixed liquor, for example according to a diurnal cycle. For example, air flow to the membrane supported biofilm can be below an average or initial air flow rate during a period of low ammonia loading. Air flow to the aerobic mixed liquor may remain essentially constants during the same period. Optionally, mixed liquor around the membrane aerated biofilm modules may be aerated during a period of high ammonia loading.Type: GrantFiled: June 27, 2018Date of Patent: June 13, 2023Inventors: Dwight Cornelius Houweling, John David Ireland, Douglas Joseph Thompson, Jeffrey Gerard Peeters

Publication number: 20230079372Abstract: This specification describes a membrane aerated biofilm reactor (MABR) and processes for nitritation, nitritation-denitritation or deammonification. The supply of oxygen through the gas-transfer membrane is limited to suppress the growth of nitrite oxidizing bacteria (NOB). Exhaust gas from an MABR unit may have an oxygen concentration of 4% or less. The process can optionally include one or more of: intermittent (batch) feed of process air; process air modulation; process air direction reversal; process air recycle; and, process air cascade flow. The process can optionally include adding a seed sludge containing anammox to a reactor, optionally after pre-treatment and selection. The process can optionally include pre-seeding an MABR media.Type: ApplicationFiled: February 10, 2021Publication date: March 16, 2023Inventors: JOHN DAVID IRELAND, ZEBO LONG, DANIEL COUTTS, DWIGHT CORNELIUS HOUWELING, JEFFREY GERARD PEETERS, MORENO DI POFI, SVEN BAUMGARTEN

Publication number: 20210171375Abstract: Wastewater with high ammonia concentration is pre-treated before discharging it into a wastewater treatment plant treating lower strength wastewater, for example an activated sludge plant treating municipal sewage. The high strength wastewater is pre-treated to oxidize ammonia by contact with a fixed film supported on gas transfer membranes in a membrane aerated biofilm reactor. The pre-treatment may be a batch or continuous process. The pre-treatment can be controlled to remove ammonia to about the point of material alkalinity depletion. One or more parameters such as alkalinity, pH, or membrane exhaust oxygen concentration can be monitored to determine if alkalinity depletion has occurred or is about to occur. In some examples, the high strength wastewater is blended with wastewater having less ammonia and more alkalinity, for example municipal sewage or primary effluent. In some examples, the high strength wastewater is a liquid fraction of one or more sludges.Type: ApplicationFiled: May 11, 2018Publication date: June 10, 2021Inventors: Dwight Cornelius HOUWELING, Douglas Joseph THOMPSON, Jeffrey Gerard PEETERS

Patent number: 10662099Abstract: A bioreactor has a biofilm that receives a gas through a supporting membrane and another biofilm attached to an inert support. The first biofilm is aerated through the membrane and provides nitrification. The other biofilm has an anoxic or anaerobic zone and provides denitrification. A module useful in the bioreactor has cords potted in at least one potting head. Optionally, some or all of the cords have a gas transfer membrane. The module may provide inert supports, active gas transfer supports or a combination of both types of support. Multiple modules may be assembled together into a cassette, the cassette providing inert supports, active supports or a combination. The module or cassette may have an aerator for mixing or biofilm control.Type: GrantFiled: June 25, 2015Date of Patent: May 26, 2020Assignee: BL Technologies, Inc.Inventors: Pierre Lucien Cote, Jeffrey Gerard Peeters

Patent number: 10486992Abstract: A membrane bioreactor (MBR) has membranes comprising a supporting structure. A supply unit doses a sorbent such as powdered activated carbon (PAC) into the MBR. The PAC is maintained at a concentration in the mixed liquor of 200 mg/L or more. Mixed liquor with the sorbent particles recirculates within the MBR at a flow rate of at least twice the feed flow rate. Air bubbles are provided to scour the membranes including during at least part of a permeation step. The sorbent particles are present in the mixed liquor and contact the membranes. Bioaugmentation products may be immobilized on PAC or other carriers and then added to an MBR or other bioreactors.Type: GrantFiled: December 7, 2012Date of Patent: November 26, 2019Assignee: BL TECHNOLOGIES, INC.Inventors: Sijing Wang, Nicholas William H.
