An ultrafiltration system has a plurality of filter modules coupled in a parallel arrangement. The flow rate at the output of each filter module is detected. When the flow rate of a given module falls below a threshold value, that module is disconnected from the ultrafiltration system and automatically coupled into a regeneration circuit so that the filter module can be cleaned. Once regenerated, the filter module is recoupled into the ultrafiltration system. If the regeneration circuit is already in use when a filter module is detected to be in need of regeneration, that module is placed in a queue for regeneration once the regeneration circuit is free, and all other modules previously placed in queue have been regenerated. While awaiting regeneration, the filter modules are kept in service in the ultrafiltration system.
