CO2 Carbonic Acid Feed System

DeNora TETRA-  CO2 pH Adjustment - Carbonic Acid Feed System

Carbon dioxide gas is injected into an alkaline or near neutral pH water stream. The gas reacts with the water (H2O) in the side stream of water to form carbonic acid (H2CO3). TETRApHix® pH adjustment offers an efficient carbon dioxide dosing system . Unlike other carbon dioxide dosing systems, TETRApHix®is uniquely classified by the AWWA standards as a weak acid dosing system, allowing for more optimal plant process designs with reduced contact times. Being a weak acid system, gas/water reaction basins are able to be reduced or eliminated. The use of a NanoBubble Diffuser allows for an efficiency of over 99%. Gas loss to the atmosphere as a result of degassing of the main process water is significantly reduced, lowering annual O&M cost and making this technology more environmentally friendly. It also has one of the lowest mixing contact time of all gas dosing technologies which decreases system footprints.
