How it works? Water Purifier
Bilkul Bazaar | Sunday Special
Ever wondered what happens to water after you pour it into a home water purifier?
A modern purifier can use multiple stages of treatment to make water safer and improve its taste.
1. Pre-filter — The First Clean-up
The incoming water first passes through a filter that removes larger particles such as dust, sand and dirt.
2. Sediment Filter — Removing Fine Particles
A finer filter catches suspended particles that may have passed through the first stage.
3. Carbon Filter — Improving Taste and Odour
Activated carbon helps remove chlorine, unpleasant odours and some organic impurities, making the water
taste better.
4. RO Membrane — The Main Filtration
In an RO (Reverse Osmosis) purifier, water is pushed under pressure through a very fine membrane. It can remove many dissolved substances, including excess salts and certain contaminants.
This is also where the purifier produces reject water, because not all the incoming water passes through the membrane.
5. UV — Using Light Instead of Chemicals
Some purifiers add a UV (ultraviolet) stage. UV light is used to inactivate microorganisms such as bacteria and viruses.
6. Final Filter — The Last Polish
The purified water may pass through another filter before reaching the storage tank or drinking outlet. Some models also add minerals or adjust taste.
So, what is actually happening?
Water enters → filters remove particles → carbon improves taste → RO removes many dissolved contaminants → UV can inactivate microorganisms → final filtration → drinking water.
THE BUSINESS BEHIND THE PURIFIER
A water purifier isn’t just a machine sold once. It creates a continuing business through filter replacements, membranes, servicing, installation and annual maintenance contracts.
That makes the purifier industry a good example of a product + after-sales-service business model.
BILKUL SIMPLY:
We use water every day. But behind every glass of purified water is a chain of filters, membranes, technology—and a business model.
