Low Profile

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 build-up 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

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

Here is a list of some of the contaminants being successfully stripped by ShallowTray low profile air strippers. If you have these or any other volatile contaminants, contact North East Environmental Products.

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.
