Publication number: 20200078741Abstract: A method of cleaning a membrane surface immersed in a liquid medium with a fluid flow, including the steps of providing a randomly generated intermittent or pulsed fluid flow along the membrane surface to dislodge fouling materials therefrom. A membrane module is also disclosed comprising a plurality of porous membranes (6) or a set of membrane modules (5) and a device (11) for providing a generally randomly generated, pulsed fluid flow such that, in use, said fluid flow moves past the surfaces of said membranes (6) to dislodge fouling materials therefrom.Type: ApplicationFiled: October 25, 2019Publication date: March 12, 2020Applicant: Evoqua Water Technologies LLCInventors: Fufang Zha, Gerin James, Joseph Edward Zuback, Peter Zauner, Roger William Phelps

Patent number: 8956464Abstract: Methods for cleaning polymeric microfiltration or ultrafiltration membranes. The membrane may be contacted with a first cleaning solution including at least one oxidising agent. A second cleaning solution including at least one reducing agent may then be introduced to the membrane and first cleaning solution. The oxidising and reducing agents may undergo a neutralisation reaction to form an oxidation-neutral mixed cleaning solution. The membrane may be simultaneously cleaned during the neutralisation reaction.Type: GrantFiled: June 11, 2010Date of Patent: February 17, 2015Assignee: Evoqua Water Technologies LLCInventors: Peter Zauner, Fufang Zha

Publication number: 20120285885Abstract: Aspects and embodiments of the present application are direction to systems and methods for treating fluids and to systems and methods for cleaning membrane modules used in the treatment of fluids. Disclosed herein is a membrane filtration system and a method of operating same. The membrane filtration system comprises a plurality of membrane modules positioned in a feed tank, at least one of the membrane modules having a gas slug generator positioned below a lower header thereof, the gas slug generator configured and arranged to deliver a gas slug along surfaces of membranes within the at least one of the membrane modules. The membrane filtration system may further comprise a global aeration system configured to operate independently from an aeration system providing a gas to the gas slug generator. The global aeration system may be configured and arranged to induce a global circulatory flow of fluid throughout the feed tank.Type: ApplicationFiled: February 14, 2012Publication date: November 15, 2012Applicant: SIEMENS INDUSTRY, INC.Inventors: Gerin James, Roger Phelps, Peter Zauner, Fufang Zha, Joseph Edward Zuback, Edward John Jordan, Wenjun Liu
