Oxygenation of wastewater

Using oxygen to increase the dissolved oxygen content of wastewater results in better system health and operability. If the current system is unable to handle increased loading or more stringent discharge requirements, oxygen can be a low-cost solution in lieu of a major capital investment. Dissolved oxygen can be impacted by our wastewater treatment solutions. The removal of excess gases from air injection can be an easy way to decrease VOC emissions. Our oxygen injection systems can also reduce the amount of BOD and COD in water treatment plants and meet even the strictest water permit limits and lower the energy consumption as well. Air Liquide can help you to collect and send ozone off gas to aeration basin to replace air for bacteria respiration thus can greatly reduce your cost both in CAPEX and OPEX and improve your performance of aerobic process meanwhile.
