The urinal is designed with a built-in waste trap. A scented, biodegradable, fully refined
vegetable oil, floats on top of the urine in the waste trap.
The oil forms a liquid seal,
preventing urine smells from being released into the air. As the urine drains through
the holes in the stainless steel cover, it passes through the oil and out of the
waste pipe. In effect the waste trap acts as an “S bend”. |
