SFBS and SCVS Members! Join us at the Chef’s Experience for
our December Dinner meeting with a presentation by Lance P. Salerno on
Development and Implementation of a Stepwise Commissioning Approach for a Major
Thickening and Temperature Phased Anaerobic Digestion (TPAD) Project
José Santa Clara Regional Wastewater Facility recently completed a Digester and
Thickener Facilities upgrade (DTFU) project. The project converted and upgraded
dissolved waste activated sludge air flotation thickeners (DAFTs) to
co-thickening capability and the mesophilic digestion process to a temperature
phased (thermophilic/mesophilic) anaerobic digestion (TPAD) process.
project was still in early construction, the team modified the original
approach from starting up the entire construction contract as one massive new
system to a stepwise sequenced approach, that commissioned different process
functions and areas over about a two-year period. The objective of the stepwise
approach was to simplify the amount of startup activities that occurred at one
time and mitigate impacts to day-to-day plant operations with process
changeovers, control system integration, plant staff time for training, new
operations and maintenance activities, and it allowed engineering and
construction teams to focus efforts sequentially rather than solving problems
with the entire system at once.
commissioning approach included a series of smaller system startups that were progressed in a stepwise manner and
generally consist of: (1) New DAFT
startup and thickening of only waste activated sludge (WAS), (2) Primary sludge
screening and co-thickening WAS in the new DAFTs, (3) Co-thickening operations
with polymer in the new DAFTs, (4) New TPAD digester operations (startup initially
in a fully mesophilic arrangement), (5) TPAD digester operations using
thermophilic digestion followed by mesophilic digestion operations, (6) Fully
integrating gas systems with cogeneration, and (7) Optimization of long term
operations through post commissioning activities.
discussion will present a high-level case study of the approach used to
commission this complex project.
