The leader in onsite wastewater technology AIR SEAL DIFFUSER

The Only Non-Clog Diffuser You Can Buy

The heart of every extended aeration wastewater treatment facility is its air diffusion system. The diffuser introduces the large amounts of oxygen required to meet the demands of the aerobic digestion process. It also mixes that oxygen with activated sludge in the tank to provide complete treatment. But not all diffusers are the same.

Some are not more than pipe pieces with holes drilled to release air. Others use spring-loaded valves. Some are simple porous structures. No matter what they are made from or how they release oxygen into the plant, they all diffuse air upward - and that's why they all quickly clog up. During off-cycle periods when air is not being circulated, solids in the aeration chamber settle to the bottom to clog the diffuser opening. The result: air flow is reduced or completely stopped, and the plant must be shut down so the diffusion system can be cleaned.

Now consider Jet's Air Seal Diffuser: its exclusive cone-shaped design causes settling solids to slide down the sloped sides and away from an opening that faces down, not up. When the blower shuts down, the opening is immediately and securely sealed with a rubber diaphragm. A bubble of air is trapped there to prevent any liquids or floating solids from coming into any contact with the diffuser opening. Clogging is
made impossible.

How Jet Air Seal Diffusers Work

Air pumped through the piping of the plant's diffusion system must be broken into small bubbles for better oxygen transfer efficiency. Streams of air passing through JET Diffusers are first broken up when passing through the sectioned orifice. Next, the rubber diaphragm, blown aside by the force of air rushing in, continues to break up the air stream. Finally, notches at the base of the diffuser break the air into still smaller bubbles giving greater surface area for more contact with the wastewater. This greater bubble surface area transfers much more oxygen to the wastewater than large bubbles do. The end result is high oxygen transfer efficiency and a mixing action giving smooth, even, fast aeration process.

JET Diffusers installed in the diffuser bar at fixed intervals provide maximum air and thorough mixing of the tank contents.

No Clogging! No maintenance! Owners save money because they save labor and replacement parts, and the plant continues to operate at peak efficiency. They can be used on new plants or as replacement parts on existing plants. JET's AIR SEAL Diffuser is simple in design and effective in operation. It is the one truly non-clog diffuser on the market!
