Waterless urinals are an innovative and eco-friendly solution designed to save water without compromising hygiene. Unlike traditional flushing urinals that use gallons of water per flush, waterless urinals operate on a gravity-based system. The core principle behind their functionality lies in a sealant liquid, typically made of lightweight oil, that is poured into the urinal bowl. This liquid creates a barrier that prevents odors from escaping while allowing liquid to pass through. When urine enters the urinal, it flows down through the oil layer, which separates it from the surrounding air. Meanwhile, the sealant liquid retains its effectiveness by slowly releasing a pleasant fragrance. This process ensures that the urinal remains odor-free. Since water isn’t necessary for flushing, waterless urinals significantly reduce water consumption and help conserve this valuable resource.
Technology behind waterless urinals
Waterless urinals utilize an innovative technology to efficiently and effectively manage waste without the need for water. These urinals employ a combination of gravity, liquid barrier seals, and specialized cartridges to ensure a hygienic and odor-free experience.
When a person uses a waterless urinal, the urine flows down through a drain and passes through a liquid barrier seal. This seal is typically made of a lighter liquid, such as a mixture of oil and blue dye, that floats on top of a heavier liquid, like a mineral oil. The purpose of this barrier is to prevent any urine odors from escaping into the restroom.
The urine then moves into a specialized cartridge that contains a highly porous material, such as a non-woven fabric or foam, which acts as a filter. This material traps any solids and prevents them from entering the plumbing system, ensuring that no blockages occur.
Inside the cartridge, there are also bioenzymes or bacteria that actively break down the urine and neutralize any odor-causing compounds. These microorganisms work to convert the nitrogen in the urine into harmless substances, minimizing any potential odors.
As the urine passes through the cartridge and gets filtered, the liquid drains into the sewer system, leaving behind only the solids and residue within the cartridge. This process eliminates the need for water to flush the urinal, making waterless urinals an eco-friendly alternative that conserves water and reduces wastewater generation.
