Drinking water plant technologies, including RO, ultrafiltration, and ozonation, treat raw water through filtration, chemical dosing, and sterilization to ensure safety and regulatory compliance. Key processes include coagulation, sedimentation, sand/carbon filtration, and, for bottled water, multi-stage RO, UV disinfection, and packaging.

Key Technologies in Drinking Water Treatment

Modern water plants utilize a combination of physical and chemical processes to remove contaminants:

Membrane Filtration (RO/UF/NF)

Reverse Osmosis (RO) removes dissolved solids, while Ultrafiltration (UF) and Nanofiltration (NF) effectively eliminate bacteria and impurities.

Pre-treatment Systems

Pressure Sand Filters (PSF) remove suspended matter and turbidity using layers of sand, gravel, and pebbles.

Activated Carbon Filtration

Removes color, odor, and organic contaminants from the water.

Disinfection Systems

Ozone generators and Ultraviolet (UV) sterilizers are used to kill pathogens.

Advanced Contaminant Removal

Technologies like AMRIT are used for removing specific contaminants such as arsenic, iron, and fluoride.
