  • Descriptive Overview
    EOOS offers a novel source-separation interface that can be adapted to multiple squatting and pedestal applications and materials (e.g., ceramics and plastics.) The interface passively separates urine and, when combined with available third party components, also efficiently separates solid feces and flush/wash water. Separation of urine and blackwater waste streams at the source, allow for urine harvesting and greatly simplifying sub-sequent treatment processes, particularly nitrogen capture. The interface is compatible with wide range of “reinvented toilet” treatment solutions for both liquids and solids.
  • Use Case Details
    Can support solid/liquid separation in a variety of user interface configurations for single- or multi-stall toilets. Appropriate for wipe or wash installations with any flush water source.
