An aeration system is among the most energy-intensive operations in wastewater treatment systems and is responsible for between 50-90% of total energy consumption in typical municipal installations. The optimum bubble size for aeration with compressed air and no mechanical mixing typically is considered to be 1 to 2 mm in diameter. This range of bu...

Membrane Degassing to Remove Dissolved Gases

What is Degassing?

Degassing is removing dissolved gases from liquids.

Applications includes:

  • Removing biogenic hydrogen sulfide from
  • groundwater, used for drinking water
  • Removing carbon dioxide from water used
  • for regenerating ion exchange resins
  • Removal of dissolved oxygen from boiler feed water
  • Removing ammonia from wastewater

BIOLOGICAL TREATMENT OF EXHAUST GASES

Biofiltration is an effective treatment technology that has been successfully applied for treating air emissions of a wide variety of chemicals.  

Biofiltration has several advantages over thermal destruction, especially in terms of lower investment and operating costs, low energy consumption, and substantially less carbon dioxide emissions.

One of the central environmental issues is the existence of failed septic tanks that are currently polluting ground water, and surface water bodies. In 2014 there were about two million septic tanks that have failed in this country, while approximately 730,000 more new septic tanks are being installed each year. In most cases, septic system fail...
