FAQ

How does it work?

Over 90% of the Odor in a Urinal comes from the plumbing. It is in the plumbing line that the germs have time to multiply and produce odor.
If this odor is prevented, most of the hygiene issues related to smell will be solved.
Vyuh is a Unidirectional-BiFluid Valve.
It allows the first fluid, Urine to flow down while preventing the second fluid, Odor, from flowing back out of the Urinal.

What is the Environmental Impact ?

Only 3% of water on earth is fresh water.
A typical urinal uses anywhere between 3 liters (regular urinals) to 15 liters (for western toilets) of fresh water per flush.
Annually a single urinal could use an equivalent of fresh water in three average sized swimming pools.
The sewage treatment plants are overwhelmed by the excess water that needs to be treated.
We are wasting fresh water to flush urinals that could otherwise be used for drinking!

How much can you save?

By installing Vyuh on your Urinals you save up to 171,000 liters of fresh water per urinal per year. Cost of water varies from place to place but could be significant in many areas and therefore your savings would also be much higher.
You also save on the electricity costs
You do not need to spend on scents.
If your urinal is based on sensors, you would also save on parts that need replacements like the solenoid valve.
If the urinals are used more frequently then the savings are even higher.
You could continue enjoying an odor free environment while saving on all your expenses.
Plumbing Lines do not clog as hard scales do not form with Vyuh and hence you save on maintenance as well.

What creates odor in a urinal?
Urine in general does not produce odor as soon as it leaves the body. Only when it comes in contact with water does the hydrolysis reaction occur. This reaction produces the malodor.
Why should we eliminate water usage completely?
Going back to the origins, the urine is produced inside the body by the kidney. Amazingly the kidney does so by putting various salts and acids in equilibrium before sending it to the bladder. While urine is stored in the bladder, it never happens that either ammonia or some other gas is released within the body. It is only when the urine meets the water outside the human body that most of the odor is released as explained earlier. Therefore the first step to eliminate odor in a urinal is to eliminate the water.
Wouldn’t salt deposits increase with pure Urine flowing through the pipes?
Have you ever heard someone complaining about salt deposits in their urinary tract? Are there any surgical procedures to remove salt deposits from the Urinary bladder? NO, Never. Salts don’t deposit within the bladder or even in the urinary tract that has a relatively small diameter. This is because the constituents of the urine are still in equilibrium. However only when water is added this equilibrium is easily disturbed and all problems begin – salts deposit, odor is released, and bacteria tend to multiply.
If the equilibrium is not disturbed then the urine would flow out of the pipes just as it flowed out of the urinary tract prior to exiting the human body. We recommend that you pour one liter of hot water every day in the urinal for maintenance, any organics that might stick to the pipes will also melt away and leave the pipes.
Wouldn’t the germs multiply on the surface of the urinal pan and cause problem to the users?
Firstly, experimental observations have shown that waterless urinals have up to 5 times less bacteria on the surface when compared to water flush urinals. Therefore, there is less chance of getting an infection from waterless urinal than a water flush urinal.
Secondly, waterless urinals promote No-Touchtechnology, wherein the user no longer has to touch the knob to flush the urinals (as in manual flush urinals). Therefore, the direct transfer of bacteria from the dirty knob to the skin does not occur when this technology is implemented.
Finally, in water flush urinals the water used for flushing is always released from the top of the urinal. Since the altitude is relatively high the chances of water splattering the residual urine from the floor of the urinal pan on to the user is very high. However, in waterless urinals the splatter has to come from the urine released by the user itself. This does not happen as the urine has to hit the floor of the pan and then the back of the wall and then finally reach the point beyond the point of origin. This usually does not happen. Furthermore, if a urinal mat is used the urine is further slowed down and no splatter occurs. Therefore, using waterless urinals is more hygienic than using water flush urinals in every possible way.
Aren’t the sensor-based water flush urinals better?
NO, they are not. Sensor based urinals waste enormous amounts of water. They are prone to breakage, the springs used break easily and cause leakage. More water is wasted in a continuous leak than in the occasional water flush. Hence cutting off the water completely also cuts off the water leakage completely and henceforth saves significant amount of water.
Urine tends to splatter back on to the skin after use, wouldn’t the urine of others splatter on to your skin? Isn’t that disgusting?
Most of the splatter is caused by the water used to flush the urinal. The water is usually released from the top of the urinal and as it falls down it splatters and causes droplets to leave the surface of the urinal and land on the skin of the user. However when waterless urinals are used, only the urine of the user causes splatter. However this splatter is in the forward direction towards the urinal pan’s back wall. Some splattered droplets could still leave the back wall but generally cannot reach the skin of the user as they do not have sufficient energy to reach the area beyond the point of origin. Hence the waterless urinals are still more hygienic than the water flush urinals.
What happens to the stains that form on the urinal pan?
We recommend that the urinal be cleaned twice a day. The recommended means is to create a phenyl solution in a bucket, then soak a piece of cloth in this solution and then wring it and use it to wipe the urinal. When yellow stains appear, one could use the scotch-brite pad to scrape the surface clean and then use minimal amount of water to rinse the pan.
How much water can Vyuh save?
Depending on the foot traffic, a singly Vyuh can save up to 171,000 liters of fresh water per urinal per year.
What is the pay back period?
Depending on the foot traffic and the cost of water in a particular region, the payback period is anywhere between 3 months to 1 year.
How we will install in concealed drain because now a days in most of the urinal we found concealed drain system instead of exposed drain.
Vyuh can be installed in any urinal with space underneath the urinal. However, if there is not enough space then the device can be installed away from the urinal in the pipeline in vertical position. Access for maintenance has to be provided in these circumstances.
Can we install this component ( VYUH ) in horizontal position.
No, this device operates only in vertical orientation. We are developing a variant of Vyuh for horizontal installation, but that will take time.
No Smel device is mandatory or not with this ?
No, NoSmel is usually used with toilets and not with urinals.
Urine already have 95 % water content and in-organic salt like Ammonia so odour is there itself. So how we will make it zero by just cleaning the urine area by two times in day.

How does Vyuh work?
As the urine flows down from the urinal into the plumbing pipes it looses potential energy and gains kinetic energy. If a turbulence is triggered, it will feed on the potential energy and cause the speeding fluid to turn into a vortex. The float within the cartridge would then tend to turn with the vortex gently and as it does that the fluid escapes around the float. The float itself does not raise much above the hole at the bottom, but as soon as the fluid is emptied the float sits back on the hole and closes it automatically. Once the hole is closed, any odor trying to escape back into the toilet is completely blocked and this is how the odors are prevented by Vyuh.
We have some proprietary unique coatings on the cartridge that helps maintain the necessary boundary conditions for the vortex to form every single time it is used. The float is also coated with this unique material that helps the device function.
