In the realm of environmental and water treatment, efficient removal of dissolved oxygen is crucial for various applications. This is where Deaerators, particularly those employing Jet Trays, play a vital role. One prominent manufacturer leading the charge in this field is Cochrane Inc., known for their innovative and reliable water treatment solutions.
Understanding Jet Trays and Deaeration
Deaerators are essential components in systems where dissolved oxygen can cause detrimental effects. They work by stripping dissolved oxygen from water, typically through a combination of heat, vacuum, and mechanical action. This creates an environment where dissolved oxygen can escape, thus preventing corrosion, fouling, and other problems.
Jet Trays are a key part of some Deaerator designs. They function by creating a high-velocity water stream that induces the release of dissolved oxygen. The tray's unique design ensures efficient contact between the water and the vapor phase, maximizing oxygen removal.

Deaeration, the process of removing dissolved oxygen from water, is a critical step in many industrial and environmental applications. Various techniques are employed to achieve effective oxygen removal, each with its own strengths and limitations.
This technique utilizes the physical properties of dissolved oxygen to facilitate its removal. It relies on the principle that the solubility of oxygen in water decreases with increasing temperature and decreasing pressure.
Types of Physical Deaeration:
This technique involves the use of chemicals to react with dissolved oxygen and remove it from the water.
Types of Chemical Deaeration:
This technique uses specialized membranes to selectively remove dissolved oxygen from water. These membranes have pores that allow water molecules to pass through while blocking oxygen molecules. This method is energy-efficient and can achieve very low oxygen levels.
Jet Trays, integrated within specialized deaerator designs, play a crucial role in enhancing oxygen removal efficiency. These trays utilize a unique design and high-velocity water flow to create an environment that maximizes oxygen release from the water.
