Technology / Service Summary

By installing special fiber carriers, the treatment capacity can be increased, energy saving, low cost can be expected. In addition, it can also be used in temporary wastewater treatment facilities.

Purpose

Stable sewage and factory wastewater treatment

Feature

1. Hight density of microbes on the fiber media
2. Possible to deal with high density wastewater
3. Reducing the amount of excess sludge generation
4. No need to return sludge
5. Stable treated water quality
6. Easy to apply to existing water tanks
7. Reducing operating cost by the reduction of excess sludge and streamlined operation
8. Long lifespan (more than 15 years)

Effect

1. Rapid start-up of wastewater treatment facilities
2. Reducing greenhouse gas emissions from sludge incineration
3. Minimizing the energy consumption by reducing the amount of sludge
4. Upgrading the capacity of existing wastewater treatment facilities
