Techniques

Chapter 1: Techniques

Deaeration Techniques for Water Treatment:

Deaerators are crucial for removing dissolved gases from water, protecting systems and improving efficiency. Different techniques are employed to achieve this, each with its advantages and disadvantages.

• Spray Deaeration: This technique utilizes a spray chamber where water is atomized into fine droplets, maximizing contact with air. The Spraymaster deaerator utilizes this principle, ensuring efficient gas removal even at low pressures.
• Vacuum Deaeration: This method involves lowering the pressure in a closed chamber, causing dissolved gases to escape from the water. Vacuum deaerators are suitable for high-quality water treatment but require more energy and maintenance.
• Thermal Deaeration: This technique involves heating water to a high temperature, reducing the solubility of gases. Thermal deaerators are effective for removing oxygen but can be energy-intensive.
• Chemical Deaeration: This method uses chemicals like sodium sulfite or hydrazine to react with dissolved oxygen, removing it from the water. Chemical deaerators are simpler to install and operate but introduce chemicals into the water.

Spraymaster Deaeration:

The Spraymaster deaerator utilizes the spray deaeration technique, optimized for low headroom applications. Its unique design features a spray tray, where water is sprayed through a series of nozzles, maximizing contact with air. This efficient design allows for effective deoxygenation even at low pressures, making it suitable for a variety of water treatment applications.
