US 2018/0243694 A1: Apparatus And Method For Reverse Osmosis (2021)
Abstract: An apparatus for reverse osmosis, the apparatus comprising: a single-stage reverse osmosis (SSRO) unit; and a counter-current membrane cascade with recycle (CMCR) unit comprising a plurality of stages of reverse osmosis including at least a first stage and a second stage wherein permeate from the first stage is configured to be introduced as feed to the second stage; wherein retenate from the SSRO unit is configured to be introduced as feed to the first stage, and wherein product obtained using the apparatus comprises permeate from the SSRO unit and permeate from a last stage of the CMCR unit.

US 2014/0254323 A1: Method And Apparatus For Determining Biofouling Of A Membrane (2015)
Abstract: A method of determining a state of biofouling of a membrane is provided. The membrane is contained within a flow cell and the flow cell has an outer surface coupled to a tranducer, The method comprises introducing inorganic particles into the flow cell such that the inorganic particles form a part of a top surface of a foulant layer on the membrane. The transducer then emits acoustic waves towards the membrane and an acoustic signature of reflected sound waves are detected. A state of biofouling of the membrane is determined based on the detected acoustic signature. A method and an apparatus are also provided for determining a state of biofouling in commercial membrane modules such as spiral wounded membrane modules.
