BlueInGreen, LLC recently completed a full scale demonstration of its proprietary CDOX® technology at a 120 million gallon per day (MGD) drinking water facility in the Midwest and is currently demonstrating at a municipal water treatment plant in another major city in the Midwest. The CDOX system dissolves carbon dioxide (CO2) gas into a small quantity of the treatment plant’s water and then disperses the dissolved CO2 solution into the rest of the water for the purpose of precise pH adjustment and stabilization of municipal/industrial water and wastewater. Controlling the water’s pH is necessary in order to ensure desired chemical reactions occur to remove contaminants from the water.
Due to new regulations concerning disinfection by-products, an increasing number of facilities are adding processes that utilize CO2 for pH adjustment. In addition, many treatment facilities are concerned for the safety of their employees due to the use of mineral acids, such as sulfuric, and are looking for a safer alternative. Others are looking for ways to improve efficiency and control over their existing pH adjustment processes to save money and improve water quality.
Such is the case at the 120 MGD facility mentioned, where recarbonation has historically been achieved using CO2 gas delivered via fine bubble diffusers. BlueInGreen’s CDOX system provided tighter control over pH and reduced total CO2 usage by 40% on average while using process water as the side-stream source and utilizing flow rates five times less than other systems on the market. This operations cost savings translates to a 3 year return on investment.
The company’s patented CDOX technology is unique in the industry, in that it is highly efficient, delivering nearly 100% utilization of vaporized gas. Recent installations have shown that BlueInGreen’s CDOX process makes it possible to deliver large qu
