Solinst-Model 703- Waterloo Emitter?

Assist in-situ remedial biodegradation of MTBE, BTEX and other contaminants.

It enables oxygen (or hydrogen for anaerobic remediation) to diffuse through silicone or LDPE tubing in a controlled uniform manner. The simple, low-cost, patented technology has a PVC frame wrapped with tubing that can be pressurized to get the desired diffusive transfer of gas. Sized for 2", 4" and 6" (50, 100 and 150 mm) wells, the units can be stacked in a well and joined from one well to another, to allow the controlled continuous diffusion of gas into the plume.
