Filtration Process: A Closer Look at RO5DX and RCC7AK
The filtration process is a critical component of any reverse osmosis water filtration system. It determines how effectively the system removes contaminants and impurities from the water, ensuring that you have clean and purified drinking water. Let’s take a closer look at the filtration processes of the Express Water RO5DX and iSpring RCC7AK to understand their capabilities and performance.
Express Water RO5DX Filtration Process:
The Express Water RO5DX utilizes a 5-stage filtration process to deliver purified water. Each stage plays a crucial role in removing different types of contaminants and improving the overall water quality.
- Sediment Filtration: The water first passes through a sediment filter, which removes larger particles such as dirt, rust, and sediment. This stage acts as a preliminary barrier, protecting the subsequent filters and enhancing their lifespan.
- Activated Carbon Block Filtration: In the second stage, the water flows through an activated carbon block filter. This filter effectively removes chlorine, volatile organic compounds (VOCs), odors, and other common chemicals that can affect the taste and smell of the water.
- Reverse Osmosis Membrane: The third stage is the heart of the RO5DX system—the reverse osmosis membrane. This high-quality membrane is capable of removing microscopic impurities such as bacteria, viruses, lead, arsenic, fluoride, and other dissolved solids. It effectively filters out contaminants, ensuring the production of clean and purified water.
- Activated Carbon Post-Filtration: After the water passes through the membrane, it undergoes an additional filtration stage with an activated carbon post-filter. This stage further enhances the taste and removes any remaining odors or residual contaminants, providing a final polish to the purified water.
- Final Polishing: The last stage involves a final polishing step, ensuring that the water is crisp, clear, and free from any remaining impurities before it reaches the dedicated faucet for consumption.
iSpring RCC7AK Filtration Process:
The iSpring RCC7AK takes filtration a step further by incorporating a comprehensive 6-stage process. In addition to the stages included in the RO5DX, it features an additional stage for remineralization.
- Sediment Filtration: Similar to the RO5DX, the RCC7AK begins with a sediment filter that removes larger particles and sediment from the water.
- Granular Activated Carbon (GAC) Filtration: The water then passes through a granular activated carbon filter, which effectively reduces chlorine, odors, and other common chemicals.
- Carbon Block Filtration: Next, the water flows through a carbon block filter, further removing chlorine, VOCs, and other contaminants that can affect the taste and smell of the water.
- Reverse Osmosis Membrane: As in the RO5DX, the RCC7AK features a high-performance reverse osmosis membrane that filters out microscopic impurities and dissolved solids, ensuring clean and purified water.
- Post-Carbon Filtration: After the water passes through the membrane, it undergoes an additional stage of filtration with a post-carbon filter. This stage helps eliminate any remaining taste and odor issues, providing a final touch to the purified water.
- Remineralization: The unique feature of the RCC7AK is its dedicated remineralization stage. In this stage, the purified water passes through a mineralization filter that adds essential minerals such as calcium, magnesium, and potassium back into the water. This not only improves the taste but also provides potential health benefits associated with these minerals.
It’s important to note that while both systems employ effective filtration processes, the inclusion of a remineralization stage in the iSpring RCC7AK sets it apart from the Express Water RO5DX. The remineralization stage in the RCC7AK adds an additional layer of benefits by restoring essential minerals that are often lost during the filtration process. This results in improved taste and potential health advantages associated with mineral-rich water.
Conclusion: express water vs ispring
In conclusion, both the Express Water RO5DX and iSpring RCC7AK are commendable reverse osmosis water filtration systems that excel in providing clean and purified drinking water for your household.
The Express Water RO5DX offers a reliable 5-stage filtration process, easy installation, and compact design, making it suitable for smaller households.
