Definitions

  • the present disclosure relates to a device having a filter core that is useful for separating solid particles from fluids.
  • Water filtration is an issue for communities around the world. Additional challenges to water filtration can arise in a myriad of situations. For example, the quality of the water can change based on weather, such as storm run-off. In some process, large amounts of solid byproducts that have wide ranges of sizes can be formed in certain processes or after weather events, and they become difficult to filter in large volumes as the solids increase clogging in filtration systems.
  • Various techniques have been suggested to improve the scale of filtration for large communities like cities. For example, cross-flow filtration has been suggested to increase the volume of water that can be separated from undesired solids, which thus increases water recovery. See e.g., U.S. Patent Application No. 2021/0268448A1 and 2016/0375380A1 . However, there is a desire to improve these techniques to support recovery of larger volumes of filtered water from unfiltered water.

  • the present teachings provide a cross-flow filter that is configured to separate fluids from particles by moving fluids into an inlet and moving the fluids across a screen. As fluids are moved across the screen in a path that is helical, some of the fluids are separated from the particles and are directed across the screen and subsequently directed out a filter outlet. The fluids containing particles that are not filtered across the screen follow a helical path down the filter and into a waste outlet as a waste fluids. The waste fluids are subsequently recycled back to the inlet through a recycle loop or are disposed of.
  • the screen can include slots that have a width that is larger than the diameter of the particles that are separated from the fluids.
  • the fluids containing the particles are moving at a speed along the screen such that the filter separates small particles with larger slot sizes.
  • Larger slot sizes can be advantageous because centripetal forces on the particle coupled with fluid drag forces associated with cross-flow filtration have the ability to move a small particle across a larger screen slot, preventing it from passing through the screen and into the filter fluid, which also reduces clogging frequency as compared to other techniques of filtering.

  • a device may be configured to receive fluids that have not been passed through the device and may have another inlet configured to receive a recycle stream of fluids that have passed through the waste outlet. This may be advantageous to recycle waste fluids through inlet again while mixing with unfiltered fluids that have less particles so that the combination of fluids desirably moves along the screen.
