Patent number: 7922910Abstract: An aeration system for a submerged membrane module has a set of aerators connected to an air blower, valves and a controller adapted to alternately provide a higher rate or air flow and a lower rate of air flow in repeated cycles. In an embodiment, the air blower, valves and controller, simultaneously provide the alternating air flow to two or more sets of aerators such that the total air flow is constant, allowing the blower to be operated at a constant speed. In another embodiment, the repeated cycles are of short duration. Transient flow conditions result in the tank water which helps avoid dead spaces and assists in agitating the membranes.Type: GrantFiled: September 17, 2010Date of Patent: April 12, 2011Assignee: Zenon Technology PartnershipInventors: Pierre Lucien Cote, Arnold Janson, Hamid R.

Publication number: 20090134092Abstract: An element for use in ultrafiltration or microfiltration of potable water has a large number of small diameter hollow fibre membranes attached between two headers. Side plates attached to the sides of the headers define vertical flow channels containing the membranes. The elements may be placed side by side and stacked on top of each other to form cassettes having continuous vertical flow channels through the entire cassette. The membrane modules or cassettes may be arranged to cover a substantial part of the cross sectional area of an open tank. Tank water may flow upwards or downwards through the flow channels. A tank may be deconcentrated by at least partially emptying and refilling the tank with fresh water while permeation continues. Excess tank water created during deconcentration may flow generally upwards through the modules and out through a retentate outlet or overflow at the top of the tank.Type: ApplicationFiled: October 23, 2008Publication date: May 28, 2009Inventors: Steven Kristian Pedersen, Pierre Lucien Cote, Arnold Janson, Hidayat Husain, Manwinder Singh

Publication number: 20080203019Abstract: A membrane batch filtration process has a step of reducing the water level in the tank by permeation prior to emptying the tank to reduce the volume of water drained after each batch. Permeation may continue even after a portion of the membranes is exposed to air to further lower the water level. The membranes may be backwashed after the water level has been lowered. The water level may be lowered again after the backwash. The tank drain may begin with a portion of the membranes exposed to air.Type: ApplicationFiled: May 13, 2008Publication date: August 28, 2008Inventors: Nicholas William Harcsar Adams, Manwinder Singh, Kevin Simon Joseph Dufresne, Pierre Lucien Cote

Publication number: 20070051679Abstract: A process and apparatus is described for filtering water with immersed membranes. In a batch process, permeate is withdrawn while the flow of feed is reduced or stopped at the end of a permeation cycle. The water level is reduced to a level where a portion of the membranes are exposed to air before draining the tank. In this or another process, the level of liquid is reduced to correspond with an area of the membrane fibers having an accumulation of solids. Aeration is provided for a period of time with the liquid at this level to dislodge at least a portion of the solids from the membranes. In these or other processes, the tank is partially drained between cycles to deconcentrate the tank, aeration is provided during backwashing and intermittently while permeating, and/or retentate is withdrawn from the tank during a portion of a permeation step.Type: ApplicationFiled: August 24, 2006Publication date: March 8, 2007Inventors: Nicholas Adams, Manwinder Singh, Fraser Kent, Pierre Cote, David Ross, Kevin Dufresne
