Advanced wastewater treatment plants in lagoons combined with biological contactors
Keyword(s):
Full-scale investigations have demonstrated that wastewater lagoons combined with rotating biological contactors can be installed for denitrification without much effort when designed for nitrification. By recirculation of a mixture of nitrified wastewater and biological sludge from the outlet of the high loaded sedimentation tank back to the inlet of the sedimentation pond the removal efficiency was consistently high combined with a high process stability. In addition a considerable amount of enhanced biological phosphorus removal could be attained simultaneously.
