How a Commercial RO Plant Works

1. Raw Water Intake: The process begins by drawing raw water from an available source, such as a municipal supply, borewell, or natural water body. The raw water is first filtered through a coarse filter to remove larger particles and debris.

2. Pre-Treatment: The pre-treatment stage is crucial for ensuring the longevity of the RO membranes and efficient filtration. Water typically passes through:

   • Sediment filters to remove suspended solids like dirt and sand.
   • Activated carbon filters to eliminate chlorine, chloramine, and organic compounds that could damage the RO membranes.
   • Water softeners may also be used to remove hardness-causing minerals, such as calcium and magnesium, which can lead to scaling on the RO membranes.

3. Reverse Osmosis Filtration: The pre-treated water is pumped under high pressure through the RO membranes. The membranes allow water molecules to pass through while rejecting dissolved salts, minerals, heavy metals, bacteria, viruses, and other contaminants. The result is purified water (permeate), while the contaminants are flushed out as concentrated brine (wastewater).

4. Post-Treatment: After the RO process, the permeate may undergo additional post-treatment processes to further improve water quality:

   • UV Sterilization: A UV lamp is used to disinfect the water by eliminating any remaining pathogens.
   • Mineralization: Some systems reintroduce essential minerals to the purified water, improving its taste and quality.
   • pH Adjustment: This step ensures the water's pH is within the desired range, making it suitable for consumption or specific commercial applications.

5. Storage and Distribution: The treated water is stored in clean, sanitary tanks and can be distributed to different areas within the commercial establishment as needed. The storage tanks ensure a steady supply of clean water throughout the day.

6. Brine Disposal: The brine, which is the waste product of the RO process, must be safely disposed of. Many commercial RO systems are designed to minimize the volume of brine produced, and waste disposal is done according to local environmental regulations.
