Fayetteville, Arkansas (PRWEB) August 06, 2013
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 quantities of gas in very small quantities of water – as much as 10 times less than the competition. This smaller carrier stream translates to reduced pumping costs as well as lower capital costs since smaller diameter piping, valves, flow meters, and other required components can be used.
Whether compared with conventional gas injection diffusers or other dissolved CO2 injection systems, the CDOX stands out with accurate pH control and reduced costs.
BlueInGreen, LLC is an environmental technology company established in 2004 to develop and sell high-efficiency, dissolved gas delivery technologies for use in wastewater, drinking water, and aquatic ecosystem restoration. The Company’s high-efficiency dissolved gas delivery systems include SDOX® (Super Saturated Dissolved Oxygen) for enhancing biological treatment processes, SDOX®-CS for odor and corrosion control of gravity sewers and force mains, HyDOZ® (Hyper-concentrated Dissolved Ozone) for disinfection, and CDOX® (Carbon Dioxide) for pH adjustment, water stabilization, and remineralization. BlueInGreen is actively addressing the global clean water supply and quality crisis by providing innovative products for improving water quality at lower cost and higher efficiency.
