How Do Waterless Urinals Work?
March, 8th, 2013
You can easily find waterless urinals in a majority of busy public restrooms. Typically, building owners believe that they can save hefty amounts on water consumption and sewer charges for countless flushes by installing dry urinals.
A waterless urinal may appear like a normal urinal. The only difference is that it does not have an exclusive tube to take in water. Men utilize them like any regular urinal, but they don’t have to flush. However, these urinals are based on the phenomenon of gravity. Since their drainage tubes are connected to a building’s plumbing structure, these waterless urinals send your waste to special water management plants.
Working of a Typical Urinal
If you do not regularly flush a normal urinal, it may stink and ultimately block up. Additionally, an unclean urinal may have a dreadful impact on the overall cleanliness of the bathroom. A regular urinal may cost a lot to operate and disregard water consumption policies. A majority of blockages in waste tubes of a normal urinal occur when the limescale present in water combines with different salts found in urine.
A washroom using soft water is less likely to experience severe blockage issues. The waste tubes of urinals serve as a place where limescale and urine mix to cover the surface with a solid scale. Eventually, various layers are added until the tube is completely blocked. This covering provides a perfect setting for the growth of stench causing germs.
Working of Waterless Urinals
Similar to a normal flush urinal, the structure of a waterless urinal is made of porcelain or vitreous china. A majority of waterless urinals employ a fluid sealer and depend on a certain degree of density difference between the waste and the sealant. Since the sealant has lesser density than urine or water, it forms a blocking wall between the urinal and the waste.
One of the most important benefits of waterless units is that they do not utilize any water. Some waterless urinals are designed to use a special cartridge that gathers fragments and other debris to avoid drain blockage problems within the waste tubes. The most accepted waterless urinal structures employ microbiological treatments to deal with liquid waste as soon as it comes into the waste tube. With these treatments, urine is broken down into various components to avoid sludge formation.
Despite various effective techniques, you may have to observe periodic manual flushing in some waterless urinal systems.
