Water is one of the most essential things for human survival. Even though more than 70% of the earth is covered with water, only about 2% of that is freshwater and less than 1% of that is accessible to us. Even this little water has to go through several purification processes before it is fit for human consumption. You don’t want to risk drinking water that is not purified beforehand, especially when the news is filled with waterborne diseases that take the lives of millions of people every year!
The simple solution to ensuring the purity of the water you drink is treating water with Reverse Osmosis (RO). This technology purifies water by removing large particles, ions, and molecules that are not healthy by filtering it through a semi-permeable membrane. This is one of the most reliable methods for purifying water. Today, the number of RO water vending machines in public places has increased exponentially. This makes it easier for the general public to drink purified water even when they are on the go.
However, the RO mechanism requires that the membrane and/or filters are replaced anywhere from 6 months to 24 months, depending on the system. The problem is that very few public RO water dispensers have indictors to show when it’s time to change the filter. So it is quite possible that people will be drinking water that has not been purified, if the filter is not changed on time, which would defeat the very purpose of the water purifier.
It is to solve this problem and ensure the continuing health of the population that Vee Technologies’ Information Technologies division designed a special application and screen for water dispensers which display the quality of water. The results displayed are based on testing the TDS (Total Dissolved Solids) and bacterial counts of the water in the dispenser. The results displayed are always real time results.
For increased transparency, Vee Technologies developed an Android app for the display that connects with an external camera device. This captures the live water surface images which are then displayed to the public in real time. It shows the quality of the inlet water and outlet water. The touch screen display shows information related to the TDS matrix in a way that is easily understandable to anyone. The display also has an inbuilt color coding which shows when the water is safest to drink (green), moderately safe to drink (yellow), and completely unsafe to drink (red). This alerts the public to the quality of the water. It also alerts the vending machine service staff that it is time to change the filter and membrane.
Vee Technologies’ live quality checking app for water vending kiosks will go a long way to ensure that the purity of drinking water at public places will always be safe, thereby ensuring the health of the public.
