What is 7 Stage Water Purification?
A 7 stage water purification system is a comprehensive filtration process that removes contaminants and impurities from water, making it safe for consumption. This method combines multiple filtration technologies to enhance water quality by eliminating particles, bacteria, chemicals, and other pollutants. Understanding the stages of this system can help you choose the right water purifier for your needs.
How Does 7 Stage Water Purification Work?
A 7 stage water purification system uses a combination of mechanical, chemical, and biological processes to ensure water safety. Each stage targets specific contaminants, providing a thorough cleansing.
1. Sediment Filtration
The first stage involves sediment filtration, which removes large particles like dirt, sand, and rust. This step protects the subsequent filters from clogging and ensures efficient operation.
2. Activated Carbon Filtration
In this stage, activated carbon filters trap organic chemicals, chlorine, and unpleasant odors, improving taste and smell. Activated carbon is effective due to its large surface area and porous structure.
3. Reverse Osmosis
Reverse osmosis (RO) is a critical component that removes dissolved solids and heavy metals like lead, arsenic, and mercury. This process uses a semi-permeable membrane to separate impurities from water molecules.
4. Ultraviolet (UV) Sterilization
UV sterilization targets microorganisms such as bacteria and viruses. By exposing water to ultraviolet light, this stage effectively deactivates pathogens, preventing them from reproducing.
5. Ultrafiltration
Ultrafiltration is a membrane filtration method that removes particles and microorganisms larger than 0.01 microns. It serves as an additional barrier against bacteria and viruses.
6. Mineralization
In the mineralization stage, essential minerals like calcium and magnesium are added back to the water. This process enhances the water’s taste and provides health benefits.
7. Post-Carbon Filtration
The final stage involves post-carbon filtration, which polishes the water by removing any remaining odors and improving taste. This step ensures the water is crisp and refreshing.
Benefits of 7 Stage Water Purification
Understanding the advantages of a 7 stage water purification system can help you make an informed decision.
