Apparatus, system and method for integrated filtration and reverse osmosis desalination

An apparatus comprising:

• a filtration device including a filtration module, the filtration device being configured to generate a filtrate from an input through at least one of microfiltration or ultrafiltration;
• and
• a desalination device fluidly connected to the filtration device, the desalination device configured to perform reverse osmosis desalination on the filtrate to generate a permeate stream and a concentrate stream, wherein the filtrate travels from the filtration device to the desalination device without traversing a storage tank;
• wherein in a first mode of operation, the filtration module performs filtration as part of generating the filtrate;
• wherein 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, wherein the output includes the concentrate stream;
• and
• wherein:
• the filtration device includes a plurality of filtration modules including the filtration module;
• each of the plurality of filtration modules is independently configurable into the first mode of operation or the second mode of operation such that when a subset of the plurality of filtration modules are in the second mode of operation, the filtration device produces the filtrate using a remaining subset of the plurality of filtration modules in the first mode of operation.

An apparatus comprising:

• a filtration device configured to generate a filtrate from an input through at least one of microfiltration or ultrafiltration;
• and
• a desalination device fluidly connected to the filtration device, the desalination device configured to perform reverse osmosis desalination on the filtrate to produce a retentate and a permeate;
• a pump fluidly connected to the filtration device and the desalination device such that the filtrate traverses the pump before being provided to the desalination device;
• and
• a controller configured to adjust a variable frequency drive setting of the pump based on a feed flow rate at an input to the desalination device,
• wherein the filtrate travels from the filtration device to the desalination device without traversing a storage tank.
