ShallowTray Air Strippers
what can they do...

These systems are designed to remove gases from water. They are great for VOC, radon and carbon dioxide removal. When used for carbon dioxide removal they become an excellent chemical free low maintenance corrosion control device. Models are available for maximum flows of 10-550gpm. All models can be used on lower than rated flows to increase removal efficiencies. Take a minute read this information over and contact us to size your unit. We can model removal rates and help you choose the model that best suits you needs.


Low Profile

The Model Pictured is a 2631 which is capable of handling flows from 2-115 gpm. (4'2"W X 6'2"L X 4'5"H)

The discreet size of a ShallowTray® air stripper does not advertise a contamination site. It is easily accessed for maintenance and can be installed inside a building. The system is also ideal as a trailer-mounted portable stripper for pump tests, pilot studies, short-term cleanup, or emergency response. There is no tower.

Resistant to Fouling

ShallowTray systems are resistant to fouling problems. Treatment trays have large 3/16" (4.8mm) diameter holes. In addition, the turbulent action of the froth scours the surfaces of the tray, reducing buildup of oxidized iron. If, under extreme conditions, oxidized iron accumulates or hardness begins to scale up, trays can be easily cleaned through ports using a washing wand and pressure washer. Trays can also be easily removed for a thorough inspection and cleaning.

Full Range Turndown

Not only are ShallowTray systems forgiving of “surprise” inorganics in the water, they also allow operation anywhere within the rated flow range. In fact, as the flow rate is reduced, performance increases. Also, as demands change (stricter effluent contaminant levels) so can the ShallowTray system. Its modular design allows for the addition of trays which increase the removal of contaminants.

No Disposal

ShallowTray systems have no packing or diffusers to contend with, and no costs associated with GAC breakthrough, fouling, or disposal and replacement.

Guaranteed Performance

Air is blown up through hundreds of 3/16" (4.8mm) diameter holes in the tray. The air forms a froth of bubbles approximately 6 inches (15.2cm) deep on the tray, generating a large mass transfer surface area where the contaminants are volatilized.

North East Environmental Products guarantees your system will perform as specified under the given operating conditions.
Treatment

The ShallowTray process uses forced draft, counter-current air stripping through horizontally extended trays to remove volatile organic compounds from water. Contaminated water is sprayed into the top inlet chamber through a coarse mist spray nozzle. The water flows over a distribution weir and along the tray. Clean air, blown up through 3/16" (4.8mm) diameter holes in the tray, forms a froth of bubbles generating a large mass transfer surface area where the contaminants are volatilized. The necessary contact time to reach required volatilization is achieved through model size, addition of trays, and flow rate selection.
