1. Available for high concentration organic wastewater

• It can be used for high influent BOD wastewater (from thousands to tens of thousands mg/L).

2. Available for high loading operation

• Compared with the loading of a conventional activated sludge system (0.2〜0.4kg-BOD/kg-SS・day), it is possible to operate by high loading (3~5 times of conventional).

3. Direct treatment of emulsified oil

• Yeast has various enzyme activities, and it is possible to remove high molecular organic matter like oil and starch rapidly.
  Particularly, a high removal performance can be achieved with emulsified oil.

4. Low excess sludge rate

• Originally, the growing speed of yeast is lower than other aerobic microorganisms, so the volume of excess sludge will become smaller.

5. No need to refill yeast sludge

• Suspended yeast type can keep the high concentration yeast sludge with the return sludge, and media yeast type can keep the yeast by rapid fixing on the surface of the media.
  ※Except the long time shut down period condition.
