A new Trickling Filter / Solids Contact (TF/SC) process was designed, constructed, and commissioned for the City of Hayward, CA in the 2000 2010 decade. Modern design features were employed for system components that provide flexible and energy efficient process control. The design included further development of a TF biofilm predator control system that provides operators with opportunities to inhibit proliferation of snails and other nuisance organisms in the TF system. Commissioning experience provided a notable confirmation of the effect of TF organic loading on the bioflocculation performance of the coupled solids contact process.
