Activated Carbon Filter (ACF) |
 |
|
 |
|
| Eliminates load of total suspended solids in the raw water. |
|
Activated carbon is prepared by slowly heating coal or coconut shell. This filter removes most of the organic contamination and pesticide residuals from the water. It also controls taste and odour of water. |

| Ultraviolet Disinfection (UV) |
|
Ultra Filtration |
 |
|
 |
|
| Water is exposed to UV light of wavelength 245 nanometers (nm). A dosage of 16000 microwatt/sq.cm. at 40°C for effective disinfection. |
|
Ultra filtration is a low pressure membrane process that removes dissolved organic macro molecules, viruses, Pyrogen enzymes etc. |

| Reverse Osmosis |
|
Ozonation |
 |
|
 |
|
| A high pressure membrane process to eliminate dissolved impurities like unwanted salts and retain minerals which are essential to human body. This done by carefully selecting the membrane by a technology developed by DIL. |
|
Ozonation is the strongest oxidizer and disinfection agent which acts on broad spectrum of microbiological organisms. Oxyrich is disinfected by 0.3 ppm of ozone. Ozone is 30000 times more effective than chlorine. Use of chlorine is eco unfriendly and produces THMs (tri-halomethanes) in water, which can cause cancer. |
