Abstract
An apparatus includes 1) a filtration device including a filtration module to generate a filtrate from an input stream; 2) a desalination device fluidly connected to the filtration device; and 3) a controller configured to direct operation of the filtration device and the desalination device. In a first mode of operation, the filtration module is configured to perform filtration as part of generating the filtrate. In a second mode of operation, the filtration module is configured to receive an output from the desalination device such that the output backwashes the filtration module. The controller is configured to monitor a change in membrane resistance of the filtration module during the first mode of operation, and is configured to trigger the filtration module to enter the second mode of operation based on the change in membrane resistance.
