To refute the widely spread prejudice about urinals: If urinals smell, they never smell of urine.
Urine is aseptic and works disinfecting. A urinal smells because urine together with water and aerial oxygen leads to a
chemical reaction. Thus, a badly smelling ammoniacal gas is produced. Where there is no water, there is no smell.
Urinary calculus, this tough accretion which develops in drains and siphons of conventional urinals and clogs them up,
inevitably leads to a bad smell. The designation "urinary calculus" in fact is wrong because this matter basically consists
of the calculus contained in water which together with the ureae then becomes an insult to our nose. Pure urine cannot turn
into urinary calculus. Where there is no water, there is no urinary calculus.
Conventional urinals are hatcheries for germs, bacteria and mould because they need a humid climate and
water to flourish. After a flush-ing, they proliferate explosively. A dangerous place of contamination also is the press
button of a conventional urinal. It is here you easily capture a virus from the person who pressed before. Conventional urinals have a flushing brink,
underneath of which it is never cleaned. All what possibly makes you ill - germs, bacteria, fungi, mould - flourishes here.
In short: Where there is no water, no press button and no flushing brink, there is no urinary calculus, no bacterial
contamination, no smell.
