Water is an essential component in many industrial processes, and its quality directly affects the outcome of operations and product success. One critical aspect of water treatment is the removal of dissolved gases, especially oxygen, which can lead to problems such as:
- Reducing corrosion in boilers and piping
- Improving process efficiency
- Enabling ultra-pure water for high-technology processes
- Improving beverage shelf life and taste
This is where water deoxygenation systems can be helpful.
What is Water Deoxygenation?
Water deoxygenation is the process of removing dissolved oxygen from water. Various methods are utilized, from rudimentary and less reliable approaches to more advanced and precise technologies. These processes also differ in labor needs, energy demands, and oversight requirements. Common processes include boilers, vacuum towers, sparging systems and membrane contactors.
While each method has merits, some are more effective and efficient than others.
Types of Water Deoxygenation Systems
There are various water deoxygenation systems designed to meet different needs.
- Boilers Use heat to raise the water temperature and drive off gases. They are often used in places with plenty of available energy in the form of heat, where a high water temperature is either advantageous or not of concern. This includes power plants, steel mills, etc. Boilers have a significant energy demand and can present safety hazards due to the heat and pressure they generate.
- Vacuum Towers: These systems subject water in a tower to vacuum, creating a partial pressure imbalance that transfers gases from the water to the atmospheric environment in the tower. The gases are pulled out of the tower through the vacuum pump and exhausted. These systems can reduce dissolved gases to very low levels, but they can be slow, maintenance-intensive, and relatively large.
- Sparging Systems: Sparging systems bubble inert gasses through a water reservoir to displace the oxygen. These systems can be labor intensive, require large tanks of water, and typically work in a batch process that takes hours per batch to achieve low levels of dissolved oxygen.
- Membrane Contactors: Continuously transfer molecular dissolved oxygen across a semi-permeable hollow fiber membrane. Water flows continuously across the outside of the fiber while a small amount of oxygen-free sweep gas flows through the inside under a vacuum. The partial pressure and oxygen concentration gradient across the membrane drive the transfer. This process is compact, efficient and precise. Very low level of dissolved oxygen can be attained with continuous flow within minutes of starting the system
