EOOS Urine Trap
Unlike many Urine Diverting Dry Toilets (UDDTs), the EOOS Urine Trap toilet is a urine diversion toilet designed specifically for flush toilets.
Frontend: The frontend presents a combination of a urine diverting flush toilet as a frontend technology and a liquid solid separator. The toilet contains a backend technology that provides for three-stream separation, i.e. urine, fecal solids and fecal water separation.
Treatment & disposal: In order to separate urine, solids, and water for treatment in the backend system, the first treatment step utilizes the “Urine Trap”, which separates urine from the flush water and feces at source i.e. in the bowl of a flushing toilet. The second treatment step involves a liquid-solid separator, which separates the liquid fraction (feces water) from the solids (feces and toilet paper). The 3 waste streams can then be further processed at low-tech depending on the desired end-products, e.g. struvite, liquid fertilizer, compost, biochar and reusable water.
Structure: Made of SATO materials (TBC)
Ideal context: The “Urine Trap” can be universally applied to all typologies of wash-down toilet designs: pedestal or squat pan, cistern flush or pour flush, washers or wipers. Additionally, it does not require energy for separation nor does it require users’ behavioral change, and has the possibility to use low-tech (biological) treatment options for the streams.
