Full Stainless Steel Double Pass RO+EDI: Advanced Water Treatment Solution
The Full Stainless Steel Double Pass RO+EDI system is designed to provide superior water quality by combining advanced filtration technologies. This system uses the power of double pass reverse osmosis (RO) combined with electrodeionization (EDI) for the highest level of purification. It is ideal for applications requiring ultrapure water, such as laboratories, pharmaceutical manufacturing, and industrial processes. With its full stainless steel construction, this system ensures durability, corrosion resistance, and long-term reliability, making it the ideal choice for demanding environments.
What is a Double Pass Reverse Osmosis (RO) System?
A double pass reverse osmosis (RO) system is an advanced water treatment process that involves passing water through two stages of reverse osmosis filtration. This two-stage filtration process provides enhanced water purity by removing contaminants that may be missed during the first pass. The first pass removes large particles, salts, and minerals, while the second pass ensures even finer removal of impurities, resulting in water that meets the strictest purity standards. When combined with electrodeionization (EDI), the system can remove even the smallest remaining ions, producing ultrapure water ideal for sensitive applications.
How Does the Double Pass RO System Work?
Stage 1: Reverse Osmosis (RO) Membrane Filtration
In the first stage, the water is forced through a semipermeable membrane under high pressure. This membrane removes dissolved salts, bacteria, and larger contaminants, providing a substantial reduction in water impurities.
Stage 2: Second Pass Reverse Osmosis Water Fiiltration System
The water that has passed through the first RO membrane undergoes a second filtration pass. The second pass removes any remaining contaminants, ensuring that the water reaches extremely high purity levels. This step is essential in applications where even trace amounts of impurities could affect the final product, such as in pharmaceutical manufacturing and laboratory experiments.
Polishing Stage: Electrodeionization (EDI) – EDI Module System
After the double pass RO filtration, the water is treated with electrodeionization (EDI) technology. EDI is a chemical-free process that uses electrical currents and ion-exchange resins to remove any remaining ions from the water, resulting in ultrapure water with extremely low conductivity and total organic carbon (TOC).
