Most people all over the world favour RO water purifiers. These purification systems use an RO filter. The filter uses a reverse osmosis membrane that can purify water instantly.
The average citizens in India tend to use RO-based purifiers the most. This is because these machines are cheap and easy to install and maintain. The water from these machines helps prevent diseases.
The current RO-based purifiers have several stages of working. One needs to know more about these stages. This can help them to choose the best cleaner for themselves while purchasing. One can also be able to maintain these properly.
A person can search about the purification stages in these machines on the internet. They can use keywords like water purifier service near me in Bangalore to know more. This can help one to contact the best technicians who can educate them regarding this matter. Knowing this information can also prevent dishonest individuals from tricking them with low-quality service.
Sediment Pre-Filtration Stage
This is the first stage in the RO-based purification process. The water from any external source first needs to go through these filters. The filters contain molten polypropylene chambers.
These can absorb any dirt and sediment from water. The latest designs of these can also remove rust and metallic impurities as well. These prepare the water for further purification processes.
Carbon Pre-Filtration Stage
After the sediment pre-filters, the water moves through the carbon filtration systems. These contain activated charcoal that can remove most impurities. These are more effective in removing carbon-based impurities from water.
These filters can also remove chlorine and other chemicals too. Apart from this, the latest carbon filters are capable of removing lead. All this allows the filters to improve the taste and smell of water.
Reverse Osmosis Membrane Filtration Stage
After the pre-filtration stages, the impure water moves through the reverse osmosis membrane. The membrane separates most impurities when the water moves through it. It also removes many harmful germs too.
Most purifiers use cellulose-based and thin film membranes. A combination of these two membranes can remove harmful chemicals like chlorine. These reduce the TDS levels by removing most solid impurities.
Most manufacturers connect the membranes to a drainage system. This throws out most accumulated impurities from the membrane. One can learn more about these online using keywords like RO service near me in Bangalore. This can allow them to know how the membranes work and their efficiency.
Post Carbon Filtration Stage
The last essential step in RO purification consists of the post-carbon filters. The water goes through a carbon filter for the final purification process. Here the carbon filter removes chlorine and other chemical contaminants.
The post-carbon filter further helps to improve the taste and smell of water. It also ensures that the water does not contain too many hard minerals that are not healthy.
Other Possible Stages
Most of the RO-based purifiers in the current times have multi-stage working principles. These can consist of other filters that work alongside the reverse osmosis filter. Such a machine can have an ultrafiltration stage.
In this stage, the impure water goes through another membrane after the reverse osmosis filter. The membrane again removes most contaminants and chlorine. This primarily aims to remove chlorine and other contaminants as much as possible.
After this, the water can also go through a UV filter. This filter will use ultraviolet radiation that can kill off most germs. This can render the water completely germ free.
An RO water purifier can also contain softening and ionising stages. Generally, the softening stage comes after the pre-filtration part, although this may vary from machine to machine. The softening chamber uses ionic reactions to remove complex ions from water.
This can include negative ions like calcium and magnesium. This softens the water while reducing water pressure on the membranes. The ionisation part comes after all filters have treated the water. Here, the water goes through an ionic reaction that enhances its pH and further softens it. This makes the water better suited for drinking.
A Final Note
Currently, most RO-based purifiers have multi-stage processes. These involve many filtration systems that work along with the reverse osmosis membrane. The arrangement of the stages may vary from one purifier to another.
These purifiers have pre and post-filtration systems consisting of sand and carbon filters. The arrangement of the stages generally does not affect the water quality negatively. However, one should still enquire how one can maintain such a machine based on its stages and components.
