Publication number: 20220242763Abstract: A biological reactor system treats concentrated contaminated water with a combination of upflow and downflow bioreactors that are downstream from a reverse osmosis or other concentrator. The system may have a fail safe configuration where flush water may be introduced to the reactors in the event of a power failure or when taking the reactors offline. Many reverse osmosis systems introduce antiscalant treatments upstream so that the reverse osmosis filters do not scale. However, such treatments result in superconcentrated conditions of the antiscalants in the contaminated water processed by the bioreactors. A flushing system may deconcentrate the bioreactors to prevent the antiscalants from precipitating and fouling the bioreactors.Type: ApplicationFiled: April 13, 2022Publication date: August 4, 2022Applicant: Frontier Water Systems, LLCInventors: James John Peterson, Timothy Michael Pickett

Publication number: 20140209526Abstract: The present invention provides, in at least one embodiment, an upflow bioreactor removes trapped gases within the bed that effect water flow and a downflow bioreactor removes carbonaceous compounds and retains the particulate elemental selenium. The system integrates biological selenium reduction with biological filtration (via the downflow bioreactor) and an optional membrane filtration. The membrane filtration removes residual selenium and other particulate matter, which would get into the effluent. In one embodiment, the novelty of the invention is the utilization of an upflow bioreactor followed by a downflow bioreactor applied to selenium removal.Type: ApplicationFiled: March 14, 2013Publication date: July 31, 2014Inventors: Timothy Michael Pickett, James John Peterson

Publication number: 20130270181Abstract: Selenium in the form of a reduced species such as selenocyanate is oxidized to produce an oxidized selenium species such as selenate or selenite, and then a biological reduction process is used to remove selenium from the oxidized selenium species. In an example, a chemical oxidant is added to a wastewater containing selenocyanate to produce selenate and selenite. The partially treated wastewater is then fed to a reactor containing a fixed media supporting a biofilm with selenium reducing organisms. The selenium in the selenate and selenite is reduced to an insoluble form of selenium, such as elemental selenium, which precipitates from the wastewater.Type: ApplicationFiled: March 15, 2013Publication date: October 17, 2013Inventors: Timothy Michael PICKETT, Yanguo MA, Jill SONSTEGARD, James Scott KAIN, Dinh-Cuong VUONG, David Brian FRASER

Publication number: 20120152761Abstract: Wastewater containing soluble selenium is treated in a bioreactor. Microorganisms in the reactor reduce the selenium to elemental selenium, which is insoluble. The elemental selenium is discharged from the reactor in waste sludge. The sludge is treated to recover selenium. In one method, the sludge is washed with chemicals, for example surfactants, and agitated to disrupt the adhesion of the selenium particles to the cells. The selenium particles are then separated from the cells using a physical separation process such as a centrifuge or differential filtration. In another method, the sludge is de-watered or dried to a very high solids content. The selenium particles are dissolved using an oxidizer under high pH conditions. A solids fraction is removed from the resulting slurry. A resulting selenium brine is further refined to recover the selenium.Type: ApplicationFiled: December 17, 2010Publication date: June 21, 2012Inventors: Timothy Michael Pickett, Jill Noreen Sonstegard

Patent number: 8163181Abstract: A process has steps of one or more of aerobic treatment to remove COD and nitrify a waste stream, anoxic treatment to denitrify a waste stream, anoxic treatment to remove selenium and anaerobic treatment to remove heavy metals and sulphur. The process may be used to treat, for example, FGD blow down water. The process may further include one or more of (a) membrane separation of the waste stream upstream of the anoxic digestion to remove selenium, (b) dilution upstream of the biological treatment step, (c) physical/chemical pretreatment upstream of the biological processes or dilution step to remove TSS and soften the waste stream, or (d) ammonia stripping upstream of the biological treatment steps or dilutions step. These processes may be provided in a variety of suspended growth or fixed film reactors, for example a membrane bioreactor or a fixed film reactor having a GAC bed.Type: GrantFiled: August 13, 2010Date of Patent: April 24, 2012Assignee: Zenon Technology PartnershipInventors: Jeffrey Gerard Peeters, William A.
