Odor -Free Urinals Gaining Popularity: Find Out How!

Urinal pan is a sanitary plumbing fixture for urination only. Urinals are often provided in public toilets for male users in Western countries. They are usually used in a standing position. The very notion that a ammonia and nitrogen filled bodily fluid can be disposed of by a device using no flushing or running water is truly amazing.

How do waterless urinals work?

Waterless urinals all use basically the same science.

Urine flows down the bowl of the urinal past a debris-catching strainer.

The urine then passes through a sealing liquid, usually a specially designed oil based fluid or simply vegetable oil, and collects in the waste pipe below.

The different densities of urine and oil (urine is denser than oil - oil floats!) mean that the urine sinks through the sealing liquid and the oil floats on top of the layer of urine below.

No Odor Urinals:

Any air bubbles rise to the top and escape leaving the urine in a relatively low oxygen environment. Odor is therefore trapped below the oil layer and cannot find the nose of bathroom occupants.

Types of waterless urinals

There are two varieties of waterless urinal: cartridge based and non cartridge based units. Cartridge based units use a replaceable cartridge pre-filled with sealing liquid. These units are periodically replaced as the sealing liquid is slowly eroded or degraded. Non Cartridge based systems work by simply introducing the sealing liquid into the drain hole and allowing it to naturally settle into the correct position.

History of Urinals:

Waterless urinals were introduced to the world by the Waterless Company in 1992. The first urinal used what was called an Eco Trap cartridge.

Waterless urinals are also becoming increasingly popular as the green building movement takes hold with certification programs such as LEED. Two major barriers that once stood as impediments to the adoption of waterless urinals, regulatory and facility managers, are being gradually eroded through education on the benefits, safety and easy maintenance of the urinals.
