An essential appliance is a water ATM. One can find these machines mostly in public areas. This enables many people to get a constant supply of drinking water.
The current versions of these machines have RO filters as their main constituents. This makes such machines much more efficient in producing drinking water. However, Indians do not know much about the application of RO filters in these machines.
Knowing these machines might be crucial for anyone. For example, a person who aims to set up such a machine in a restaurant or office should know how these machines work. One might also need to know how the use of RO filters can affect their maintenance.
One can search for such information on the internet. They can use keywords like water purifier service near me in Pune. This can also help them come in contact with reliable technicians. Such people can help them know more about these machines and their maintenance.
How Does A Water ATM Work?
Before knowing about the application of RO filters, one should know about the working principle of a water ATM. A water ATM derives water mainly from the local water supplies. These run on electricity. However, the amount of power consumed by such machines might differ based on their brand.
A person must use a prepaid card to get water from these machines. One might use coins to get water if the machine has such a feature. These also have customisable features.
One can use these features to set the temperature of the water or its pH levels. One can also set the amount of water one needs. These can also have features that allow one to control the TDS levels.
Application of RO Filters in Water ATMs
Like most water-purifying appliances, water ATMs also use RO filters to purify water. The latest designs of these machines use two types of reverse osmosis membranes. These are namely polysulfone and cellulose-based membranes.
These membranes separate most major impurities from water. The membranes can also have certain chemicals coated on them. The nature of the membrane’s constituents and the coating allows these to remove complex salts and chemicals.
Due to the efficient designs of the membranes, these are very efficient and long-lasting. These are also very durable and do not suffer from damage too quickly. A water ATM can have two or more sets of these membranes.
However, the amount of membrane sets or RO filters present in them depends on their design. The membrane sets in these machines also help to soften up the water. They achieve this by removing calcium and magnesium-based compounds. One can learn more about these online by using keywords like RO service near me in Pune.
Application of Other Purification Systems in RO Water ATMs
Most water ATMs do not use reverse osmosis filters alone. These latest designs use a combination of ultraviolet and ultrafiltration filters. The combination of these filters makes the water more purified.
The ultrafiltration and ultraviolet filters help to purify water in ways by which the RO membranes cannot. The ultrafiltration membranes can remove chemical impurities more efficiently. These are more durable and can remove chlorine and germs. Most water ATMs use reusable UF filters. These use reusable membranes that can cut down maintenance expenses a lot.
The ultraviolet membranes also help to kill as many microbes as possible. These use ultraviolet light for this purpose. Apart from these, nanofiltration, ozonisation, and ionisation processes also occur in a water ATM.
These processes happen in separate chambers within the machine. The nanofiltration chamber has a membrane that can remove most hard ions from water. These, however, do not cause essential minerals to separate from the water.
The water also has to pass through an ozonisation chamber. This chamber produces ozone that oxidises most metallic impurities from water. This lowers the TDS levels.
The ionisation chambers further remove the hardness in water. This happens through the ion exchange process in this component. This also enhances the pH levels of water, making it fit for consumption.
Benefits of RO Water ATMs
RO-based water ATMs are easy to maintain. The many components mentioned above lowers the water pressure on the RO membranes. As a result, the membrane or the filter itself does not get damaged easily.
The reverse osmosis filters also help to purify water even more. The presence of these filters helps the machine rectify the shortcomings of the other components. This results in the formation of healthy drinking water.
