The Traypak: A Versatile Tool for Water Treatment
In the field of Environmental and Water Treatment, the term "Traypak" refers to a specific type of equipment designed to remove dissolved gases, primarily oxygen, from water. This process, known as deaeration, is crucial for various applications, including:
- Power Generation: Deaerated water prevents corrosion in boilers and turbine systems.
- Industrial Processes: Many industrial processes, such as chemical manufacturing and food processing, require oxygen-free water to avoid unwanted reactions.
- Drinking Water Treatment: Removing dissolved oxygen helps improve water quality and extends the lifespan of distribution pipes.
How does a Traypak work?
Traypaks utilize a multi-stage tray design to effectively remove dissolved gases. Water is sprayed onto trays arranged in a vertical column, allowing it to cascade downwards. As the water falls, it comes into contact with a venting system, which removes the liberated gases. This process can be further enhanced by applying vacuum or introducing an inert gas, like nitrogen, to the system.
