Forced Draft Degasifiers

Pure Aqua Forced Draft Degasifiers are used to remove unwanted gases from supply water. The degasifier removes the gases by passing the water over a packing media that helps the water form a thin film over the surface area of the tower. A counter current airflow is introduced at the bottom of the tower and travels up the stack through the descending flow of water. The gases are stripped as the air passes over the surface area of the water.

Pure Aqua has a complete line of Forced Draft Degasifiers available. The systems start at 75 gpm and go up to 1000 gpm.

Degasifiers

Degasifiers are used in demineralizer applications to strip CO₂ following a strong acid cation exchanger or softening application. They can also be used as an economical way to strip hydrogen sulfide or volatile organic compounds (VOC). Degasifiers are sized based on water service flow rate.

Operation of the System

The forced aeration of water will obtain oxidized matter from the fluid and remove gases such as methane (CH₄), carbon dioxide (CO₂), and hydrogen sulfide (H₂S). The total removal of the gases requires previous acidifying of the fluid and the use of strong oxidizing agents such as chlorine or potassium permanganate. The raw water falls from the top of the tower onto a layer of filling elements of special shapes. This is required in order to maximize the surface area with the forced upward draft. This results in the most thorough oxidation and removal of gases carried up through the tower and collected at the top.

Here at Pure Aqua, Inc., we engineer and build all of our water treatment systems in-house.

Our turn-key water treatment systems are all pre-engineered using the latest CAD technology available.

This enables our teams to build and deliver treatment systems to our customers with quick turnaround times.

Many of our customers require custom engineered systems. These are typically built around similar core systems and thus allowing for improved turnaround times, even for one-off designs.
