SOLVOX® Oxygenation Water Treatment Solutions
oxygen is used as a feed source to an ozone generator, it can greatly increase the ozone concentration of an existing generator, or reduce the size of a new one when compared to an air feed. Water Treatment - Waste Water Treatment. In biological waste water treatment, microorganisms need oxygen for respiration. Pure oxygen is commonly used to improve aerobic activity, increase DO levels, and reduce unpleasant odors in waste water plants as compared to using air. Oxygen is used in cases... (read more)

Aerators Enhance Aerobic Digester Process
In 2003, Eden WWTP staff became aware of floating brush rotor aerators as a potential approach to providing oxygen transfer and mixing in the aerobic digester. AERATORS ENHANCE AEROBIC DIGESTION PROCESS. After installing four 20-hp aerators, the city of Eden, N.C., happy with performance, results
PTMD Scrubber Improves Odor Control at Vancouver Island Wastewater Treatment Plant
The French Creek Pollution Control Centre treats wastewater from the City of Parksville and the Town of Qualicum Beach on Vancouver Island in British Columbia. Originally, the plant used the extended aeration process with aerobic sludge digestion for wastewater treatment. From 1995 to 1997
Application of pre-acidification
tank reactor (CSTR) followed by anaerobic/aerobic series treatment. COD and TSS reductions of 34% and 80% respectively, in the acidogenic stage, resulted in effluent that responded well to the anaerobic/aerobic series treatment. The system produced final effluent in which COD and TSS had been reduced
