  • Self-adaptive control and optimization of membrane filtration
    Patent number: 10576428
    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.

  • Apparatus, system and method for integrated filtration and reverse osmosis desalination
    Patent number: 9790113
    Abstract: An apparatus includes a filtration skid configured to generate a filtrate through at least one of microfiltration and ultrafiltration. The apparatus further includes a desalination skid fluidly connected to the filtration skid. The desalination skid is configured to perform reverse osmosis desalination on the filtrate to generate a permeate, where the filtrate travels from the filtration skid to the desalination skid without traversing a storage tank. In one embodiment, the apparatus further comprises a controller, where the filtration skid and the desalination skid are integrated to provide self-adaptive operation of the filtration skid and the desalination skid in response to control by at least one of a supervisory controller and a local controller. In one embodiment, the control responds to at least one of temporal variability of feed water quality, a permeate production capacity target, and a permeate quality target.
