Waste Water Treatment Aeration Apllications

Hakko Air Pumps original use is for waste water treatment in Japan.

In fact, Hakko Air Pumps are installed in waste water treament and sewage applications around the world. This is an application that demands the highest standards in performance and reliablity.

The function of your waste water system relies heavily on a rigorous and dependable air pump. Hakko delivers.

Aeration is a critical component of waste water treatment.

An ample oxygen supply in a wastewater pond system is the key to rapid and effective wastewater treatment. Oxygen is needed by the bacteria to allow their respiration reactions to proceed rapidly. The oxygen is combined by the bacteria with carbon to form carbon dioxide.

Moving Bed FiltrationWithout sufficient oxygen being present, bacteria are not able to quickly biodegrade the incoming organic matter.

In the absence of dissolved oxygen, degradation must occur under septic conditions which are slow, odorous and yield incomplete conversions of pollutants. Under septic conditions, some of the carbon will be react with hydrogen and sulfur to form sulfuric acid and methane.

Other carbon will be converted to organic acids that create low pH conditions in the ponds and make the water more difficult to treat.

Waster Water Treatment

For example, treated ponds designed to biodegrade wastewater pollutants without oxygen often must hold the incoming sewage for six months or longer to achieve acceptable levels of pollution removal. This is because the biodegradation of organic matter in the absence of oxygen is a very slow kinetic process.
