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.
