Mechanical and Biological Start-up
AQUABIOTEC offers to his customers the mechanical and electrical start-up of his delivered equipment stations based on his long-term experience.
The biological start-up of biofiltration can usually be done without inoculation, because the necessary bacteria and microorganisms are already present in wastewater. The microorganism will be feed with the wastewater into the biofilter and settle on the filter material. Therefore, the microorganisms will produce exoenzymes for fixing on the clay. This will lead to the production of foam for several days, as a normal process.
The necessary time for biological start-up without inoculation is usually in the range between 1 and 2 weeks for full BOD elimination and about 2 to 3 months for full nitrification.
Mechanical and electrical start-up
Once the full mechanical and electrical installation is finished, the mechanical and electrical start-up starts. The start-up includes the following steps:
- Visual plant check
- Comparison between P&ID/Layout plans with real plant
- Check of necessary start-up utilities (water, air, chemicals)
- Hydraulic tests
- Mechanical and electrical functional tests
- Start-up of each equipment unit
- Test run and protocol
Biological start-up
- Biological inoculation of biofiltration (if needed)
- Putting in operation of biofilter with al related settings
- Chemicals analyse of in- and outflow waters
