    • 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.
    • 超滤系统具有并联布置耦合的多个过滤器模块。 检测每个过滤器模块的输出处的流量。 当给定模块的流量低于阈值时,该模块与超滤系统断开连接并自动耦合到再生电路中,从而可以清洁过滤器模块。 一旦再生,过滤器模块被重新连接到超滤系统中。 如果当检测到过滤器模块需要再生时再生电路已经被使用,则一旦再生电路是空闲的,该模块被放置在再生的队列中,并且先前放置在队列中的所有其它模块已被再生。 在等待再生的同时,过滤器模块在超滤系统中保持使用。
