Waterloo Emitter Enhanced Aerobic Bioremediation - Video
As oxygen gas flows through the Waterloo Emitter tubing, a concentration gradient is formed between the gas in the Emitter tubing and groundwater. Let's zoom in and take a closer look. In accordance with Fick's Law, oxygen diffuses across the tubing from higher concentration in the tubing, to lower concentration in the groundwater. Diffusion occurs until there is an equal concentration in the tubing and the groundwater. However, groundwater constantly flows past the Emitter, and the oxygen gas supply is steadily flowing through the Emitter tubing replenishing the oxygen level, therefore equilibrium is never reached. Molecular oxygen becomes available to the aerobic microorganisms that are present in the groundwater. Oxygen is critical for encouraging growth and sustaining the population of aerobic microorganisms. The natural breakdown of chemical contaminants, BTEX for example, by the aerobic microorganisms, is stimulated. Overtime, the contaminant levels in the groundwater are reduced through enhanced aerobic bioremediation.
