Waterloo Emitter: Low Cost Enhanced Biodegradation

Engineered for the Controlled Continuous Diffusive Release of:

Oxygen for aerobic bioremediation
Hydrogen for anaerobic bioremediation
CO₂ for pH adjustment
SF₆, He, Ar for tracer tests

The Waterloo Emitter™ is designed to 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 consists of a PVC frame wrapped with tubing that can be pressurized to obtain the desired diffusive transfer of gas, appropriate to site-specific needs. 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.

Waterloo Emitters used for Bioremediation Study in High Temperature and Saline Groundwater: A study was undertaken to determine the success for aerobic bioremediation of aromatic hydrocarbons (BTEX) and MTBE (methyl tert-butyl ether) in high temperature, saline groundwater conditions. The study included laboratory microcosm experiments, as well as a field trial in Saudi Arabia, in which Solinst Waterloo Emitters were used.
