Waterless Urinal Mechansim |
1. Instead of being
flushed down with as much as a gallon of water, urine simply drains
through openings in a specially designed plastic cartridge at the bottom
of the bowl.
2. The entry chamber
contains a blue liquid—a lighter-than-urine long-chain fatty alcohol.
Gravity pulls urine through the liquid, but odors and sewer gases are
trapped below.
3. As the urine
descends through the cartridge chamber, its flow collides with a
barrier, which prevents turbulence from displacing the floating sealant.
4. Urine passes beneath
the barrier and into the exit chamber. When the urine level reaches the
height of the drain, it spills over and empties into the outbound sewer
pipe.
