The AIRaider series of diffused bubble aeration systems from BGC Technologies Inc. are designed for radon and VOC removal. The systems introduce the contaminated water in a predetermined method that maximizes air-to-water contact. High-pressure filtered air is propelled through special anti-fouling diffusers that equally distribute the air in each of the treatment chambers, separating the contaminants from the water. The cleaned water awaits repressurization in a quiescent chamber. The gases released through this process are vented safely to the outside air through a 2-inch vent line. BGC Technologies Inc.
