A Reverse Osmosis (RO) system purifies water by removing contaminants and impurities through a multi-stage filtration process.
Here's a simplified breakdown of how it works:
How a Reverse Osmosis (RO) System Works:
A Reverse Osmosis (RO) system is a highly effective water purification method that removes contaminants through a series of filtration stages, delivering clean, safe, and great-tasting drinking water.
Pre-Filtration:
Water first passes through initial filters designed to protect the system and improve overall performance:
Sediment Filter:
Removes particles such as dirt, sand, and rust
Carbon Filter:
Reduces chlorine, chloramines, and chemicals that affect taste and odour
Reverse Osmosis Membrane:
At the core of the system is a semi-permeable membrane.
Water is pushed through this membrane under pressure, allowing only pure water molecules to pass while rejecting contaminants such as:
Heavy metals (lead, arsenic, etc.)
Nitrates and dissolved salts
Chemicals and impurities
Many bacteria and viruses
This stage provides deep purification at a molecular level, making RO one of the most advanced filtration technologies available.
Post-Filtration:
After the membrane, water passes through a post-carbon filter:
Removes any remaining taste or odour
Enhances the final water quality
Storage Tank:
The purified water is stored in a pressurised tank, ensuring a steady supply is available whenever you need it.
Final Polishing
Before dispensing, water goes through a final polishing filter, delivering clean, fresh drinking water straight from the tap.
Key Points to Understand:
Pressure Driven: The system relies on water pressure to operate effectively
Wastewater: A small portion of water is discharged to carry away rejected contaminants—this is a normal part of the process
Benefits of Reverse Osmosis:
Removes a wide range of contaminants including nitrates, heavy metals, and dissolved solids.
Improves taste, odour, and clarity.
Provides high-quality drinking water at the point of use.
Ideal for both town and rural water supplies.
A Reverse Osmosis system is a proven, reliable solution for households wanting confidence in their drinking water quality—especially where contaminants such as nitrates or chemicals are a concern.
