Today, waterless urinal systems are becoming more and more popular. To give you a better feel for how these systems work and why they are so beneficial, here are a few things you need to know about waterless urinals.
Below are 3 things you need to know about waterless urinals:
Typically, the bodies of waterless urinals are constructed of vitreous china or porcelain, similar to standard flush urinals. Most waterless units use a liquid sealer and rely on a density differential between the sealant and the liquid waste. The sealant is less dense than water or urine, which pass through the sealant. The sealant creates a barrier between the liquid waste and the urinal bowl. Liquid-seal urinals feature two different designs: cartridge and integrated drain trap. The cartridge design uses various types of disposable cartridge inserts that fit into the custom-designed urinal base. The cartridge might simply slide into the base, or it might require a special tool for insertion and removal. Yet another type of waterless urinal does not require a liquid seal to operate. This urinal uses a flexible silicone diaphragm or elastomeric, expanding check valve. Typically housed in a removable cartridge, the diaphragm or check valve allows liquid waste to pass through and then seals, preventing sewer gases from entering the restroom. Source: FacilitiesNet
One of the biggest challenges for green technologies is that they often produce greenhouse gases or pollutants when they’re being manufactured or used. It’s like how you might be able to drive an electric car, but if it was created at a factory which obtains its power from a coal-burning power plant, it’s actually worse for the environment than a gasoline-burning car built in a green powered factory. Waterless urinals are carefully manufactured so that when all is said and done, there’s minimal waste, and no CO2 produced in the process. Source: ZeroWaterConsulting
If you’re wondering about maintenance, it depends on the setup. Composting toilets generally require more work than incinerating toilets or waterless urinals. Basic care is throwing in dry, carbon-rich cover after each use and monitoring the compost. You have to add cover if it’s soupy or water if it’s too dry. If you’re worried about odors, many commercial toilets build in methods for preventing bathroom stench. If you’re worried about odors, many commercial toilets build in methods for preventing bathroom stench. For instance, “Envirolet” toilets use fans to pull air from your bathroom through the toilet and out of a stack on your roof. You seal gaps in the system with silicone. The fans in the toilet aerate the compost and keep the air flowing one-way. Source: ScienceHowStuffWorks
