| 11. | Mixed waste streams may be collected from materials recovery facilities or mechanical biological treatment systems.
|
| 12. | It is chaired by Dr . Montserrat Garcia Balletb? investigator of biological treatments in tissue regeneration.
|
| 13. | These facilities are called mechanical biological treatment plants.
|
| 14. | Biological treatment lagoons also use anaerobic digestion to break down solids, but at a much slower rate.
|
| 15. | Gerhard Kraft introduced it in Europe, with two significant innovations : raster scanning and biological treatment planning.
|
| 16. | In such a system, biological treatment and carbon adsorption are combined into a single, synergistic treatment step.
|
| 17. | Although towns have biological treatment equipment, as much as 50 % of such equipment is rated as ineffective.
|
| 18. | There is also the possibility of integrating with other processes such as mechanical biological treatment and anaerobic digestion.
|
| 19. | These ponds use gravity to chemical precipitation, biological treatment ( such as an activated sludge process ), and evaporation.
|
| 20. | Microbes are used to break down and convert organic substances in wastewater to microbial residue in biological treatment processes.
