US Patent 11173453 Method and device for repairing a membrane filtration module

A method for repairing a membrane filtration module in fluid communication with a plurality of additional membrane filtration modules includes fluidly connecting a fluid transfer assembly to the membrane filtration module, fluidly isolating the membrane filtration module from the plurality of additional membrane filtration modules, forcing liquid within the membrane filtration module into the fluid transfer assembly by introducing a pressurized gas into the membrane filtration module, releasing the pressurized gas from the membrane filtration module, fluidly disconnecting the fluid transfer assembly from the membrane filtration module, repairing one or more damaged membranes in the membrane filtration module, and fluidly reconnecting the membrane filtration module to the plurality of additional membrane filtration modules.
