WATER PURIFIER TECHNOLOGY

Deur water purifier uses the latest and safest methods to ensure you get safe and clean drinking water every time you feel thirsty. To keep you healthy and disease free, we use the advanced technology of Reverse Osmosis (RO). Reverse osmosis helps in removing dissolved salts as well as organics from the water.

To understand reverse osmosis better, let us tell you a little about the process of osmosis.

Osmosis is a natural and fundamental process in which a liquid is flown through a semi permeable membrane, which blocks the transfusion of salts/solutes through this membrane.

Reverse osmosis, as its name suggests is almost the opposite or reverse of osmosis. In this process, when the two volumes of any solvent or water are separated with a special grade semi permeable membrane, the normal process of osmosis starts. This means, the liquid with low solute concentration flows to the high solute concentration. Now this process is stopped or even reversed by applying pressure externally, known as osmotic pressure. In such a case, the liquid flows from the high concentrate solute to the low concentrate solute. This phenomenon is called as reverse osmosis.

During this process, a small percentage of the feed water permeates the membrane, the other portion of water (unfiltered water) moves alongside the membrane without being filtered and moves out of the system.

The stream which permeates through the membrane is called the ‘permeate’. The second stream of water is called the ‘concentrate’ because it carries the concentrated salts and other contaminants which are not able to permeate through or rejected by the membrane. Since the two streams of liquid flow side by side, this process is also called cross flow filtration. This process of water filtration ensures that the output will reject 99.9% of pyrogens, virus and bacteria.

The water that you drink from Deur water purifier passes through 5 stages of filtration and not just the process of reverse osmosis. Each stage will make your water cleaner, purer and tastier. Don’t believe us? Take a look at it yourself:



5 STAGES OF FILTRATION:

 

1st stage High-Grade 5 micron 10″ high-capacity polypropylene sediment filter – removes dust, particles, and rust. Protects and extends the life of the membrane and system
2nd Stage Premium extruded carbon block 5 micron 10″ — gets rid of unpleasant chlorine, tastes, odours, cloudiness and colours. Also removes other common chemicals from the water
3rd Stage FILMTEC (Dow Chemical) High Rejection TFC reverse osmosis membrane- removes up to 99% of total dissolved solids and contaminants such as arsenic, lead, fluoride, chromium, radium, bacteria, virus and much more
4th Stage U.V.- Provides bacterial disinfection in water
5th Stage Advanced coconut shell refining carbon 10″ — TCR (Total Contamination Removal) filter removes any possible residual taste from the tank
