#ShutTheFlushUp

A drop saved

is a penny earned

There is an acute shortage of water and a large percentage of the population does not have access to water. To add to this problem, we waste a huge amount of water in our restrooms during flushing. A conventional urinal flushes approximately 1-2 ltrs of fresh water which leads to a wastage of anything between 50K ltrs to 150K Itrs in a year.

That is one whole year of 14 families getting access to drinking water.

54% of India faces HIGH to Extremely high Water Stress.

Interestingly, the only reason we flush our urinals after urination is to get rid of the odor and the odor is nothing but Ammonia (NH3)

MYTH

Water is necessary in a urinal to flush down the #PeePee. Without water, urinals would stink.

FACT

#PeePee is 95% water and can flow down the urinal by itself. #PeePee reacts with water to produce Ammonia which is responsible for the smell.

This myth alone is costing us 2-4 liters of water for every use and spoiling our restrooms, while at it. The dampness in urinals offers favorable environment for microbes & air-borne infections. Plus, the water used for flushing urine increases volume of sewage generated in cities. We want to save this water and create an odor-free #PeePee experience.

The Science behind Urine & the Odor

Hydrolysis of urea present in human urine generates odour in urinals. The enzyme urease, hydrolyses urea into ammonia and carbamate. The latter compound decomposes spontaneously to carbonic acid and a second molecule of ammonia. The overall reaction can be represented as :

NH2(CO)NH2 + 2H20 → NH3 + NH4+ + HCO3-

Ammonia (NH3) is a colourless gas with a pungent odour. Ammonia exists naturally in air at levels between one part and five parts per billion (ppb) of air. The normal human detection level of ammonia is approximately 50 ppm, some people can detect ammonia gas concentrations as low as 20 ppm.

How Zerodor removes your restroom odor & and makes it waterless

98% of the smell comes from the drain line where urine is drained, dried and releases ammonia gas. The objective of a Waterless Urinal is to manage/block/control the odor-causing gases in the drain pipe so that the requirement of flushing the urinal pans with water is avoided. In a Waterless Urinal, a one-way valve is installed in the urinal pan which allows the urine (liquid) to flow but blocks the odor-causing gases (NH3) and keeps the restroom free from foul odor. The one-way valve can be designed using various mechanisms and ways. Conventional Waterless Urinals in the market use Chemicals and Cartridges to handle the odor & water and demand infrastructural changes during installations. These cartridges have chemicals ora gel that floats (something similar to oil floating on water) and creates a barrier for odor-causing gases.

Another mechanism uses an elastic membrane that opens and closes and thus creates a barrier for the odor-causing gases.

Our solution, Zerodor is a waterless urinal kit that converts an existing conventional flushing urinal into a waterless urinal. This replaces the waste coupling in the urinal pan. The solution has a one-way ball valve that floats up when urine passes through it, opens the drain passage, and then goes back to its original position to close the opening and thus block the odor-causing gases coming from the drain line. This helps in keeping the restroom odor-free and eliminates the need for flushing the urinal. Since this is a mechanical device and does not use any chemicals, it is a cost-effective solution and does not demand any operational expenses in terms of changing or replacing any cartridge. Also, As it is a retrofit solution, it does not demand any infrastructural change.

Comparison of Zerodor with other technologies

There are different types of waterless urinals available in the market working on different principles. Some have chemical sealant cartridge that uses chemicals or gels as a sealant to block the odor and allow passage of urine. Another technology uses a membrane-based cartridge which has a membrane flap that opens for passage of urine. Both these technologies are imported and have their own challenges and limitations. Operational and design challenges along with high cost make these technologies less suitable for the Indian context.

Here's how Zerodor Waterless Urinal compares with these technologies.
