Product Options


The Model 703 Waterloo Emitter is an inexpensive, simple device which is designed to assist in-situ remedial biodegradation of MTBE, BTEX and other contaminants. It allows the uniform and controlled release of oxygen, or other bioenhancing amendments, which encourages and sustains the growth of microorganisms required for in-situ bioremediation of contaminated groundwater.

With use of the patented technology, a steady, direct diffusion of oxygen into an aquifer through pressurized silicone or LDPE tubing is enabled. This continuous stream of oxygen into the tubing creates the ideal concentration gradient driving this passive system, without bubbling off excess oxygen.

The PVC frame is wrapped with tubing which can be pressurized to obtain the desired diffusive transfer of gas, appropriate to site specific needs. To allow the controlled continuous diffusion of gas into the plume, the units can be stacked in a well and joined from one well to another. They are sized for 50, 100 and 150mm (2”, 4” and 6”) wells.
