VOCs
Avoid VOCs stripping by reduced stirring and biodegradation.
At Nippon Gases we are called “The Gas Professionals” for a reason, and it’s because we’ll be able to solve any doubt.
Oxygen for reducing WWTP odors
The formation of odors in WWTPs is generally due to the presence of anaerobic zones, or to an insufficient capacity of oxygenation during the hot months.
Sustainability
Contribute with the healthy air in the neighborhood
Temperature
Increase oxygen OTR to overcome low O2 solubility during hot periods.
Wastewater odor is especially disruptive for treatment plants located in urban or touristic areas.
Anaerobic state of water
Elimination of anaerobic state of water.
Oxidation
Oxidation of oxydisable substances (pre-biological).
Descent of sulphides
Descent of the concentration of sulphides in the biological raft, normally toxic for bacteria.
Rapid oxidation
Rapid oxidation of sulphides to sulphates.
Higher reaction rate
Higher reaction rate with oxygen than with air, and without generating stripping.
Oxygenation
Homogenisation and oxygenation without aerosol phenomenon.
