Corporate philosophy of Aience

Aience looks at environments through water purification.

Aience looks at environments through water purification.

Aience aims to create an earth-friendly environment with cutting-edge technology.

Aience's bio-environment improvement system recovers an important environment being destroyed from a variety of causes by making use of its proprietary aeration system and natural microorganisms. From the development of this cutting-edge technology to now, we have made numerous achievements and accumulated rich expertise to realize excellent total engineering capability. As a water purification professional, we are responding to decontamination in a wide variety of fields and helping to construct a sustainable society.

The conditions for water treatment Aience advocates are...

The word "purify" is written as "浄化" in kanji, having the character "浄 (cleanse)", and this character can be further divided into two elements - "水 (water)" and "争 (battle)".


Water masses collide and fight with each in such places as the basin of a waterfall into which water runs down and the water's edge where strong waves move in. Common to these areas are an abundant amount of dissolved oxygen and the electrical effect of generating negative ions by impact, both of which have a very high purification capability. Reproducing this purification power of nature through aeration, Aience responds to purification needs for various types of contamination.


Dissolved oxygen for activating microorganisms is generated.

Microscopic bubbles are generated by a special diffusion method to increase the oxygen concentration in a tank. Oxygen is spread over to support microorganisms for aerobic respiration and maximize their metabolic and resolving capabilities.

Microorganism oxygen consumption

Microorganisms require the following amounts of oxygen.

Assuming that microorganisms and a mouse have the same weight, surprisingly, microorganisms consume the amount of oxygen 50 to 150 times the amount of oxygen a mouse consumes. For that reason, the greater load water has, more oxygen must be supplied because the amount of organic material to be resolved is greater.

Difference in metabolism and types of microorganisms

Difference in metabolism and types of microorganisms

When there is a sufficient volume of oxygen, microorganisms perform aerobic respiration metabolism like humans by breathing oxygen and releasing carbon dioxide. However, if the volume of oxygen becomes low, the process turns into anaerobic respiration metabolism due to sulfate ions, and eventually generates such a by-product as hydrogen sulfide. Moreover, when sulfate ions are consumed completely, the metabolism changes from aerobic respiration to anaerobic respiration, generating acid substances that cause rotting odors such as acetic acid and propionic acid. And, pH becomes lower for that reason.
