Commissioning of 21<SUP>st</SUP> Century Trickling Filter Process Design Features in a Trickling Filter / Solids Contact Process

Abstract

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.

Introduction of New Process Technology into the Wastewater Treatment Sector

“…However, the process still finds applications for carbonaceous only applications (Slezak et al, 2010) and in cases where high peak wet weather flows must be treated (Parker et al, 2005). From the point of view of the two versions of the S curves presented in the theory section, the technology is approaching maturity and is in the last region of the curve defined by Rogers.…”
